Galvanized steel, thanks to its resistance to rust, corrosion and outstanding durability, has become an ideal material for many industrial fields.Have you fully understood the characteristics, pros and cons of galvanized steel and how the galvanizing process takes place? AG真人游戏 Steel will get deeper into this material.Galvanized steel products are widely used in various industries due to their durability and corrosion resistanceWhat is galvanized steelGalvanized steel is a material that is coated with an outer layer of zinc to protect the product from the effects of the surrounding environment such as temperature, humidity, air,... Thereby, limiting the possibility of rust , anti-oxidation and corrosion to increase strength and life span of coils.Methods of galvanizing steelCurrently, there are 3 most commonly used galvanizing methods: cold galvanizing, hot -dipping galvanizing and electro galvanizing.Cold galvanizing methodCold galvanizing is a method of coating a layer of liquid zinc on the surface of the product at room temperature and then putting it through a cold galvanizing process. Here, the mill uses compressed air to blow a liquid solution to form a beam of zinc particles that shoots onto the metal surface. In the solution, there are additives to help the coating adhere firmly to the metal surface and harden in a short time. Cold galvanizing technology helps to improve the corrosion resistance of metal, so it is the best solution for galvanizing metal materials on site.The galvanized steel melting point typically ranges from 1420掳C to 1460掳C, depending on the specific composition of the alloyHot-dip galvanizing methodHot-dip galvanizing is the most popular coating technology today, capable of effectively protecting coils from the effects of the environment. This process starts from dipping the product into a molten solution to form a strong, non-flaking base and a smooth, highly aesthetic product surface.Electrolytic galvanizing methodElectrolytic galvanizing is a method of electrocoating that forms a thin layer of metal on the surface of a coil for the purpose of preventing metal corrosion, increasing electrical conductivity, size and hardness. In fact, the electrolytic galvanizing method is used for steel products such as water pipes, railways, outdoor equipment, bearing equipment, machine parts,...Learn about standard galvanizing processThere are 3 methods of galvanizing steel, but hot-dip galvanizing is still the most commonly used method in Vietnamese factories with the following standard implementation process:Step 1: Metal surface treatmentSteel made from iron ore or recycled steel also contains many impurities, dirt and oil that reduce the ability to adhere to the coating layer. Therefore, the material needs to be soaked in the degreasing solution for 10 - 15 minutes and transferred to a solution of hydrogen chloride concentration of 8 - 15% to remove rust.The density of galvanized steel varies depending on its composition and coating thicknessStep 2: Embed Soldering fluxAfter the steel is cleaned, it is dipped into the flux for about 3 - 20 seconds at normal temperature to completely remove the oxide and iron ions on the surface of the product. This is also the step that creates a coating that protects the steel from oxidation.Step 3: Hot dipped galvanizedSteel will be completely immersed in the galvanizing bath at the melting temperature (454 - 465 degrees Celsius) to create a layer of zinc coating on the surface. After completing the hot dipping process, performing slag scraping on the surface combined with vibration to remove excess zinc, the product will be coated with a layer of chromate to protect the surface comprehensively.Step 4: Cool down and check qualityIn order for the surface of the galvanized steel to be bright and beautiful, the product is cooled by an overflow bath. Experts observe and calculate the thickness of the coating by using specialized gauges to ensure that the finished product meets the specifications and requirements of the customer.Top reasons why you must galvanized steelLow costThe production cost of galvanized steel is much lower than other surface protection coating methods, so it is the first choice for large-scale construction projects.DurableThe zinc coating protects the coil from rust, environmental corrosion and chemical reactions of the inner steel components. According to research, GI has high durability, using life up to 50 years in ideal conditions and from 20-25 years in harsh conditions such as industrial zones, coastal areas, etc.AestheticsCompared with conventional steel products, galvanized steel has a shiny, smooth surface and is easily coated with high-grade color paint to increase aesthetics.Reduce maintenance costsGalvanized steel products have high durability, long service life, so it does not cost a lot of maintenance and regular maintenance during use.The "galvanized steel meaning" encompasses the process of coating steel with a protective zinc layer to enhance its corrosion resistanceApplication of galvanized steelGalvanized steel possesses high durability, good bearing capacity and is a familiar material in common applications such as deck floors, ventilation pipes, oil pipes, purlins, vehicle parts, household appliances, furniture,... In particular, galvanized steel is an ideal material for many important industries, specifically:Wind and solar industryThe solar energy projects need to operate continuously, so maintenance must be minimized to avoid disruptions and decrease in productivity. Additionally, due to exposure to harsh environmental conditions such as sun, wind, rain,..., the project is susceptible to deterioration and damage.Therefore, galvanized steel is widely popular in the wind and solar energy industries because of its durability, corrosion resistance and resistance to environmental factors, enduring for decades.Automobile industryGalvanized steel is an ideal material for manufacturing automobile frames and parts. Currently, about 80% of car bodies are made from galvanized steel with durability, rust resistance and many other advantages.Construction industryDurability is the top criterion in choosing construction materials. resident or commercial projects demand materials capable of bearing heavy loads, with high longevity, and minimal need for frequent maintenance. Therefore, large structural parts in buildings are often made of galvanized steel to ensure safety and sustainability.Telecommunications industryPhone lines are often in high, difficult-to-access positions, leading to irregular maintenance. Therefore, when choosing materials in the telecommunications industry, attention must be paid to sustainability and minimal maintenance requirements.The "galvanized steel meaning" encompasses the process of coating steel with a protective zinc layer to enhance its corrosion resistanceAG真人游戏 Steel: providing the benefit of importing Vietnamese galvanized steelWith investment in infrastructure, modern equipment and strictly selected raw materials, Vietnam galvanized steel mills provide product lines with thicknesses from 1.5 to 3.0mm, coating degree Z275 - Z350, strength up to G450.FDI projects especially favor these types of galvanized steel because of their durability. high quality and good resistance to environmental conditions, so the life of the works can be up to 50 years.In addition, galvanized steel also meets many international standards such as JIS G3302 of Japan, BS EN 10346 of Europe, AS 1397, ASTM A792 of the United States, conquering many difficult export markets such as the EU. , the United States, Korea and Southeast Asia,...

Purlins are one of the materials that help support the structural framework, most often below the roof. Purlins carry the roof desk load and are supported by building walls, steel beams, rafters,... Purlins are an indispensable part of every project, so choosing the perfect purlin ensures the safety of the entire building. In this article, AG真人游戏 Steel will share some tips for choosing the most suitable purlins to make the roof frame for the project.1. Choose the appropriate purlin materialPurlins combine with rafters to create a roof frame, combining the support of beam frames, walls or steel beams. When choosing the material of the purlin, importer can consider between black pipe steel, galvanized steel or high-strength steel. Each material has pros and cons in terms of strength and cost, so importers need to assess the building design to choose the most optimal material. However, to ensure the safety of the project, steel purlins must be able to withstand high loads, resist corrosion, rust and be unaffected by environmental factors.2. Choose the ideal type of purlinThis is one of the important factors when deciding which type of purlin for your project. C and Z shaped purlins are the two most popular types, have high applicability and unique characteristics as follows:C purlins are made from black or galvanized steel with a C shape and used in structural framework for factories, houses,... Importers can contact AG真人游戏 Steel for advice on the most suitable dimensions, thickness and length for their specific application.Z purlins are manufactured from hot-rolled, cold-rolled, galvanized steel, shaped like the letter Z, so it is easy to stack and connect through bolted joints. Because of this characteristic, the Z shaped purlin has a higher thickness and durability than the C shaped purlin.3. Install purlins properlyCalculating the distance to install purlins compared to the corrugated iron roof in a reasonable, economical and safe way is important in choosing purlins for the project.Firstly, safety and sustainability are the top criteria, requiring the distance between purlins and corrugated iron roofs to be standard and reasonable. Next, if the purlins are not aligned or installed too far or too close, roofing will cost a lot of time and money. Finally, if the purlin distance is not suitable, it also reduces the building's load-bearing capacity, especially making it difficult to repair and maintain periodically.4. No weld/heat cutWelding or heat cutting methods are not used when installing purlins because high temperatures can affect the durability and strength of the purlins.5. Choose a reputable supplier and manufacturerPurlins are a key part in construction projects, so factories always produce many specifications to meet all customer needs. Importers can also find cheap sources from China, India,... but for some countries with strict regulations on C/O or trade defense measures, this option is not feasible. Meanwhile, Vietnam belongs to the group of countries with a developing economy, so it enjoys many preferential duty rates and import policies to the EU, United States, Australia, Mexico, Malaysia,...Vietnam has crude steel output ranked 13th on the world steel map and the largest in Southeast Asia, ensuring abundant and high-quality supply for customers. Many of Vietnam's largest factories do not receive orders directly from importers but through intermediary support units such as AG真人游戏 Steel.AG真人游戏 Steel provides solutions for importing Vietnamese steel to more than 30 countries around the world, with a network of links with many reputable steel factories and shipping lines to promote the fastest and most optimal delivery process.

Purlins are a specialized material used in frameworks and prefabricated houses to structural support and prevent rust and termites. Vietnam's increasingly developed manufacturing techniques have created many different types and standards of purlins. 1. What Is PurlinIn construction, a purlin is a horizontal bar or beam used in a roof support system. They are most commonly in buildings and are supported by the building鈥檚 rafters and its wall. Purlins are classified based on material and shape, serving different purposes. Purlins are very important in architecture and structure because without them, we cannot tile any other material on the roof.2. Types of Purlin in Steel BuildingC Shaped PurlinC shaped purlins are horizontal C-shaped bars that are light in weight, good strength and easy processing. The flat surface of the purlin is perforated to increase flexibility during assembly and construction. They are widely used in the construction of factories, houses, warehouses, shopping centers, airports,...Products commonly used for projects with column pitch <6m with common specifications are C200x50x1.8, C150x50x20x1.5,...Z Shaped PurlinZ shaped purlins are made with oval holes to easily connect the purlins together with bolts. This type is lightweight, easy to process and has better bearing capacity than C-shaped purlins. They are mainly used in projects with large areas such as factories, cold storages, commercial centers,... The most popular specifications are Z200x72x78x2.0, Z200x62x68x1.8,...Black Steel PurlinBlack steel purlins are made from hot-rolled black steel, known for its lightness, durable, heat-resistant, environmentally friendly and less deformed under strong impacts. However, black steel purlins are less widely used, especially in high-end projects because of their low aesthetic factor, low roughness and easy rust.Galvanized purlinsGalvanized purlins are black steel purlins covered with a layer of zinc plating to protect the surface. This enhances their durability, resistant to force and temperature and are especially resistant to rust and corrosion under weather conditions. High strength purlinHigh-strength purlins are manufactured by modern technology with higher quality than conventional purlins. The product has the ability to withstand high temperatures, the yield limit reaches a minimum of 350 MPa ~ 4500kg/cm2, light weight, large spans while still ensuring deflection within the standard range.3. What Purpose Do Purlins Serve In Construction?Purlins are divided into two types: roof purlins and regular purlins. In the prefabricated steel structures, builders often connect the purlins with round or V-shaped bars to firmly stabilize the purlin system.For columns of large factories with heights of 9-12m, purlins are supported by V-shaped struts to enhance the bearing capacity of the works. In addition to the role of bearing the roof load and human load, purlins are calculated and designed to bear the hanging load of wind ceilings, duct systems, electricity or decorative furniture.4. Where To Import Reputable And Quality Purlins From Vietnam?Steel purlins are one of the highly applicable products but not all purlins from every factory meet the required standards. In particular, some countries attach great importance to the issue of C/O when importing, so purlins must prove the origin of input materials.Vietnam is a country with crude steel output ranked 13th globally, advanced production technology, imported machinery systems from the most famous metallurgical brands such as Danieli, Tenova,... This has created the quality of Vietnamese steel, making Vietnam the largest steel industry in Southeast Asia.Under the escalating world economic and political situation, finding a reputable, quality steel supply source that is not in the group of embargoed countries is difficult for importers. Understanding these things, AG真人游戏 Steel is a unit specializing in providing solutions to support the import of Vietnamese steel to more than 30 countries around the world.

Steel melting is a complex process, many stages and requires many advanced technologies to create finished products of outstanding quality, meeting the stiff demands in construction. The process has 3 main steps: iron ore treatment, blast furnace molten iron smelting and impurity treatment to form billets and finished products. In this article, AG真人游戏 Steel will describe in detail the steel melting process to help you better understand the nature of this metal.1. What is iron ore steel melting?The process of making steel from scrap steel is relatively simple because the raw material only needs to go through an electric arc furnace (EAF) or an induction furnace (IF) to smelt into square billets and roll out the final product. Meanwhile, steel made from iron ore has to go through a long process with many different complicated stages. Iron ores are rocks containing metallic minerals that are mined and processed to produce steel. Different types of iron ore contain different proportions of iron, divided into 3 basic types:Magnetite: The chemical formula of this ore is Fe3O4 containing 72.41% iron. In nature, the amount of magnetite iron ore is very rare because they possess the highest iron contentHematite: This is an iron ore with 70% iron content, after magnetite, the chemical formula is Fe2O3. In Greek, hematite ore means blood because of their characteristic red color, easily found in Asia, Australia, and Brazil.Pyrit: The chemical formula is FeS2 containing iron content up to 46.67% with metallic, golden copper color. It is the most common of the sulfide minerals.2. What is the process of making steel from iron ore?Step 1: Iron ore processingIron ore with the main components being iron oxides Fe2O3 and Fe3O4 in raw form, with different contents and sizes, processed, mixed according to the required ratio, combined with coke coal, lime and dolomite to put into the furnace to produce liquid cast iron. The product is an alloy of Fe and C with a Carbon content of more than 1.7%. Carbon is an important element affecting the hardness, ductility and toughness of steel. When %C is in the range of 0.8-1%, the steel has the best strength and hardness, but if the ratio exceeds 1%, they begin to decrease. Therefore, the manufacturer reduces C in cast iron and some other harmful impurities (Cu, Ni, Cr) to less than 0.03%. Liquid cast iron water, after being transferred to an oxygen furnace, helps to melt iron ore and reduce the level of impurities such as sulfur, phosphorus,...Step 2: Create a liquid of molten steelFrom the molten cast iron in stage 1, it will continue to be led to the basic furnace or electric arc furnace to treat impurities and combine some other metals such as manganese, chromium, nickel, aluminum, copper, ... to enhance the technical properties of the steel and create the grade required by the market.Step 3: Roll billet, finished steelWhen step 2 has been completed, the liquid metal is put into casting machine systems to form billets or finished construction steel products such as rebar, coil, hot rolled steel,....There are 3 main types of bar stock, slab and bloom, which are cast in two different states: hot casting and cold casting. For bar stock with cross section of 100x100, 125x125 and 150x150, length 6.9m or 12m  for use as coil and rebar. Slabs are often used to make hot rolled coils, cold rolled coils or V-C-U-H sections, while bloom can completely replace both bar stock and slabs.3. Vietnam's modern steelmaking technologyThanks to the closed steel melting process, advanced technology lines imported directly from G7 countries such as Tenova group, Danieli - the leading corporation in Europe and the world in metallurgical and steel rolling equipment, has turned ore into high quality products without impurities. Products after steel melting have impurities below 0.03%, lower than the standards of many fastidious import markets in the world.The process of smelting steel from ore removes many harmful impurities such as S, P, so the finished steel has strength and longer life expectancy. Steel made from iron ore possesses superior physical and mechanical properties and can be rolled into products with a higher diameter and grade of steel such as D55 construction steel, tensile strength reaching over 600N/m2, suitable for construction projects, bridges, ports, skyscrapers,鈥teelmaking is a complex production process, requiring many modern technologies and lines to ensure product quality and not cause pollution to the environment. Vietnam is one of the countries with the leading steel melting capacity in the world.

Galvalume is considered a special imported product because the process of finding out information about the item is always complicated. Galvalume steel coil specifications always come with a series of dense data in terms of width, hardness, and thickness that importers need to learn carefully before conducting a transaction.Technical Galvalume Steel Coil SpecificationsThe technical specifications are the evidence demonstrating the strength, toughness and mechanical properties of products. If you are an importer and do not know the basic specifications below before proceeding to trade the item, it is very easy to meet the situation of receiving the finished product not as expected.ThicknessThe thickness is one of the important galvalume steel coils specifications in the information description table. The thickness will certainly affect the selling price, depending on a coil of steel thickness or thin that the factory will calculate a suitable price for the buyer. Sometimes importers require oversized thicknesses, which will make it difficult to find source because not all factories can meet the special requirement of thickness in production.Currently, for Galvalume coils, the ideal thickness is usually in the range of 0.25 to 1.2 mm. The reason why is called the ideal thickness because this is the thickness range that most factories can produce and it is often widely applied in many fields.Coating thickness symbolGalvalume steel coil has 3 layers including base steel layer, aluminum zinc coating layer and color coating layer. Therefore, when viewing coating symbols, importers need to keep in mind a few definitions. There are 3 common coating thickness symbols in galvalume steel coils specifications used by steel manufacturers including BMT, TCT and APT.BMT: reflects the thickness of the base steel layer, which is the inner steel core that has not undergone aluminum galvanizing processes. Therefore, if the galvalume coil is printed with BMT, the importer should understand this as the thickness symbol of the cold rolled coil.TCT: The full name of TCT is Total Coating Thickness, which means that the thickness of the product will now include the base steel layer along with the galvanized layer.APT: APT is the only symbol for prepainted galvalume steel coil products because APT stands for After Painting Thickness, the thickness of the steel product after color plating.Width Besides the thickness, the width gauge size also plays an important role among galvalume steel coils specifications, the manufacturer will rely on these two parameters to calculate the weight of the steel coil. The common formula for calculating the weight of coiled steel applied by many factories today ism (kg) = T (mm) x W (mm) x L (mm) x 7.85Where T is the symbol for the steel thickness, W represents the width and L is the length of the coil. The number 7.85 is the density of iron in mathematics.Grade (Hardness)If thickness was a reflection of the steel's appearance, then hardness would be a measure of the strength for galvalume steel coils. High hardness means that the strength of steel is extremely good and it also shows durability. However, higher hardness also makes the steel become more difficult to handle in machining and design applications. People usually will rely on 3 criteria to evaluate the hardness of steel including: Tensile, Yield Strength and Elongation.Yield StrengthThe manufacturer will put the steel in a specialized machine and start pulling at the 2 heads of the steel, at a certain force when the steel begins to deform, the manufacturer will rely on that to record the Yield Strength of the product.Tensile If Yield Strength reflects the time to deform of steel, then Tensile will be the proof of the maximum strength of a steel product. When the tension between the two heads reaches a large enough to make the steel break at this point, it is called Tensile. Currently, the unit of measure applied to both Yield Strength and Tensile is MPA (N/m2).ElongationElongation is a measure of the distance between the beginning deformed position to the point of failure, it is calculated based on the ratio between Yield Strength and Tensile. If the percentage of Elon is large, it shows that the steel is ductile and easy to form up. Whereas the percentage of Elon is low, it means that the steel is hard and brittle, the steel structure is extremely solid but it will interfere with shaping.In addition, the steel hardness parameters shown on the information table are usually calculated based on the minimum force impact. More specifically, if the Yield Strength parameter is G300, when testing the steel standard, the manufacturer will have to use a minimum force of 300 Newtons to deform the steel.Color IDOne color tone will have many different color shades, so learning the color code before implementing trade will help importers avoid the risk of receiving wrong colors. During the negotiation process between the two parties, the manufacturer will often send to customers a RAL color system with certain symbols on them. When the customer reports the color code, the manufacturer will base on the customer's color requirements to mix the paint color.Commodity classification in galvalume steel coil specificationHS CodeHS is a commodity classification code that is applied to all countries, so when conducting commercial transactions between two countries, understanding the HS Code is the necessary action in determining the category of goods.Conventional iron and steel products refer to the first 2 digits as 72, the following numbers will classify in more detail the width as well as the thickness of the steel coil. The most common HS Code of galvalume coils today is denoted by 8 digits 72107013.Country of origin & Brand NameOne of the last galvalume steel coil specifications that importers need to pay attention to is information about the origin of the product. Possessing a certificate of origin will make the goods easier to clear and the importer can rely on it to distinguish whether it is an authentic product or a floating product on the market.Find out the good partner in removing barriers when importing Galvalume steel The expanding global economy as a trend has led to the development of cross-border commercial cooperation relationships. Unlike domestic trading, import-export trade, especially steel products, always hinders foreign importers about the diversity in price segment and the choice of Vietnamese reputable factories.Due to many years of experience and working in the steel industry, AG真人游戏 Steel is ready to accompany you in solving commercial transaction problems.

Besides the usual steels, today manufacturers have continuously innovated and released many improved steel alloys to serve diversified industries. Chromoly steel is known as a steel alloy that is lighter in weight than any other steel, but it also ensures good durability and load capacity.What is Chromoly steel and its important specificationsChromoly steel is a low-alloy heat-resistant steel formed by a combination of "chromium" and "molybdenum", of which the chromium content is 10%. The role of alloying elements will make the product have superior features to ordinary carbon steels because it helps increase durability after undergoing heat treatment.The Chromoly steel grades are conventionally identified by the first two digits of 41, to indicate that this is the designation of chromium and molybdenum steels. An example of the most common type of Chromoly steel can be mentioned as AISI 4130 steel which is currently being used a lot in the oil and gas, aerospace,...CHEMICAL ANALYSISC%Carbon 0.28 鈥� 0.33Mn%Manganese 0.40 鈥� 0.60P%Phosphorus 0.035 maxS%Sulfur 0.040 maxSi%Silicon 0.20 鈥� 0.35Cr%Chromium 0.80 鈥� 1.10Mo%Molybdenum 0.15 鈥� 0.25Some remarkable properties of chromoly steel Limitation in metal corrosionChromium is known as a metal with very high hardness, it also has amazing corrosion resistance. When chromium meets oxygen, it will form a compound Cr2O3, which is the strongest compound of chromium in anti-oxidation. So if Chromium is added to steel, it will create a more protective layer for the steel core, the more chromium content, the higher the steel's ability to resist rust.Outstanding hardnessSimilar to chromium material, when adding the molybdenum to the structure of steel, it will provide superior strength as it increases the hardness of steel and of course, the tensile strength of steel will be greatly improved. A chromium molybdenum steel plate can be designed to withstand a load force of up to 760 MPa.Thanks to this ideal hardness, Chromoly steel helps to maintain the stability of the structure, increase the load-carrying capacity, and minimize the product's warping or distortion when subjected to long-term loads.Good heat resistanceBeyond the feature of increasing hardness, chromoly steel also possesses good heat resistance properties because molybdenum compound allows the steel to survive well under temperatures up to 5800C. Molypden is a heat resistant substance in nature, when combined with chromium, this link will significantly reduce the damage of steel structures in high pressure environments.Long-term cost savingsChromoly steel will cost more than standard steel grades, but in terms of its useful applications in the long-term, this steel will provide the amount of cost-effectiveness for plan. If you are looking for a material that is stronger and lighter than steel but not as expensive as titanium, chromoly steel will be the best choice for you.List of common Chromoly steel's applications Basically, Chromoly steel has some similar features to standard carbon steel, but thanks to the addition of a chromium layer, the steel has enhanced strength and resistance to oxidation, the molybdenum content in the steel also increases toughness. Because of these superior features, the Chromoly steel line becomes useful and is being applied to many industries.Aerospace industryIn the past, steel and aluminum were the popular materials in the aviation industry, but in recent decades, chromium steels are gradually being applied and replacing traditional materials. Thanks to its thermomechanical properties, chromoly steel is often used to support jet engines and landing systems.Manufacture of vehicles and bicyclesDue to the versatile combination of durability properties as well as good load bearing, Chromoly steel is often used to make car chassis. Moreover, based on the advantages of anti-corrosion and high hardness, manufacturers often use them to make gears and automobile crankshafts.Chromoly steel is considered the best material for bicycles. Although Chromoly is known for its hardness beyond standard, it also possesses surprisingly good ductility. Thanks to this factor, manufacturers can freely shape and weld metal parts together to create trendy chassis models that still ensure good durability and bearing capacity.Chemical industriesMany studies have proved that Chromoly steel can suffer from extreme environmental temperature conditions up to 5800C for a long time. Therefore, this steel is widely used in high pressure industries such as oil filtration and chemicals.Depending on the numerous advantages that Chromoly steel brings, it is not difficult to imagine that Chromoly steel will become a standard material for many applications of the field in the future. Therefore, preparing a plan to add Chromoly steel as the main sources for your projects will be a perfect decision for future sustainable development.If you are in need of sourcing reputable Chromoly steel as well as learning more about price segments in the Vietnamese steel market, please contact AG真人游戏 Steel via Whatsapp +84 76 911 2358 or email [email protected]. 

K Span is known as a new anti-leak solution for buildings thanks to the steel material PPGI/PPGL in the K Span roofing system helps eliminate the risk of water leakage for the building. Moreover, the durability in them also supports the system becoming sustainable to inclement weather as well as providing flexibility in disassembly and relocation.Definition K Span system and its applicationK Span is the typical name for the dome structure in construction, these domes are manufactured by the forming equipment that makes them reach their full curvature and then the manufacturer will deliver them to the construction site. The entire K Span is a combination of individual pieces of corrugated iron that are connected together by a specialized jointing system, so that the pieces are tightly linked without the need for screws. Normally, the main raw material for making up corrugated iron pieces in K Span is galvanized steel or pre-painted galvanized/galvalume steel (PPGI/PPGL).The K Span system is used a lot in the field of construction, many businesses often apply them to make roofs for civil buildings, houses, barns in agriculture, in addition they can be installed as a hangar or entertainment infrastructure,...Important effects of PPGI/PPGL in the K Span roofing systemAesthetics and durability are one of the outstanding advantages of pre-painted galvanized/galvalume steel. Therefore, the application of PPGI/PPGL in the K Span roofing system has brought a series of beneficial values to the project.Simple construction for contractorSimilar to pre-engineered steel buildings, K Span owns a simple construction structure when they are an overall combination of PPGI/PPGL pieces linked through a joint system. The K Span foundation is built on an extended concrete strip surrounding the building, so the contractor will not need to drive fixed piles or beams during construction.In addition, the main structural components of K Span come from PPGI/PPGI steel, which significantly reduces the weight of the construction compared to traditional brick materials. Thanks to its light weight as well as the simplicity in installing, a K Span system can be set up in almost all soil conditions while still ensuring good stability.Flexibility in design with PPGI/PPGL in the K Span roofing systemThe K Span dome is a combination of a series of coated steel linked together and they are divided according to each span. Thanks to this flexibility, the contractor can arbitrarily change the length of the roofing as desired as they can be dismantled in individual spans. If the building is built with traditional bricks, when the contractor wants to shorten or dismantle it, it will affect the entire structure.Shorten the time for completing projectK Span is considered a system to help improve the construction process quickly because the main structural components are steel and often steel will be produced directly at the factory. After the factory has done the material as required, these parts are moved directly to the construction site, which inadvertently saves the contractor a lot of time during the building process.According to average statistics, a construction team with a number of 10 - 20 people can complete a whole installation of 500m2 per day for a K Span system by assembling the parts together accordingly. Compared with traditional construction methods, construction crews often have to spend more time in mixing mortar and disposing cement.Eliminate the risk of water leakageIn the past, traditional roofs made of mortar or bricks would be prone to leaks because of long standing water absorption. It can be seen that steel is a material that helps to resolve this situation because steel is metal in nature, so it will not absorb liquids. Possessing a K Span dome system will help users feel more secure about waterproofing.In addition, during the production process, the PPGI/PPGL in the K Span roofing system don't create any holes in the surface, there is no chance for rainwater to enter. Tthe curvature of the dome is a great design that provides good drainage when it rains or in snowy environments.High tolerance in the inclement weatherThe applications of steel in construction, especially the PPGI/PPGL in K Span roofing system is often added with galvanized layers to resist scratches as well as increase durability, prevent oxidizing agents due to chemical reaction by zinc. A project with the K Span system will require less frequent maintenance, thereby making conditions for contractors to save on periodic maintenance costs as well as limiting unwanted cost in repair during the process of using.Eco-friendly recyclingConstruction steel is considered a useful material when it can be recycled and reused consecutively throughout its life cycle without being affected by the internal structure. After a long time of use, the contractor can choose to disassemble the pieces of PPGI/PPGL in the K Span roofing system to manufacture other applications.Choose a reputable company to provide PPGI/PPGL in K Span roofing systemClimate change is becoming more obviously forthcoming such as abnormal sunshine and rain as well as high humidity, which directly affects construction works. Therefore, choosing a quality material for your construction project will be the right choice to gain long-term efficiency to the contractors.Understanding the needs of customers, AG真人游戏 Steel is here to help you find solutions in choosing quality PPGI/PPGL steel materials that come directly from large manufacturers in Vietnam.

Thanks to astute foreign policies and a favorable geographical location, Vietnam has reaped benefits in trade agreements. Among the prominently advantaged industries, the steel sector consistently ranks among the highest annual export volumes in the country. Therefore, importing steel from Vietnam not only provides cost advantages but also ensures product quality for importers.Geographical location creates favorable conditions for importing steel from VietnamIn terms of its maritime geographical location, Vietnam holds the advantage of being situated in the South Sea, which is considered a vital maritime route connecting the Pacific and Indian Oceans. Additionally, its strategic location amidst key markets such as China, Japan, South Korea, Singapore, India, and various other ASEAN countries positions Vietnam as a hub for maritime and trade activities. This not only opens up numerous opportunities for the import and export of various goods but also actively involves Vietnam in the global steel supply chain.Continuous investment in logisticsOver the years, the Vietnamese government has consistently invested in and upgraded seaports to facilitate import and export activities, aiming to reduce transportation times and alleviate bottlenecks in the flow of goods. As a result, the transportation duration of steel has significantly shortened, creating favorable conditions for steel brands originating from Vietnam to become more prevalent in various regions.Specifically, the average transportation time for goods to the Southeast Asia region has now been reduced to 5-10 days, and the shipping time from Vietnamese ports to Australia takes only 15-20 days. While Europe is considered a large market with a relatively distant geographical distance from Vietnam, significant improvements in logistics have reduced the average transportation time to just 30 days.In contrast, the geographical distance to the Americas is considerable, requiring a longer transit time, typically ranging from 45 to 60 days for steel products to reach their destination. Although geographical distance poses a challenge, in certain special cases, delivery time can become a crucial tool in pricing strategies, especially during periods of fluctuation in the domestic steel market. Specifically, during periods of high domestic steel prices, the decision for importing steel from Vietnam can bring significant benefits to importers in the Americas, providing them with a steel supply at a competitive price compared to competing counterparts and thereby reducing cost pressures.Importing steel from Vietnam brings tariff advantages via FTA agreementsAs of now, Vietnam has 19 FTA partners, including 15 active FTAs, such as the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP). This allows Vietnamese steel products to enjoy a 0% import tariff within the customs framework of the 11 participating countries. Moreover, Vietnam successfully signed the EU-Vietnam Free Trade Agreement (EVFTA). The EVFTA stands out from other trade agreements Vietnam has signed, granting nearly 100% tariff reductions for import and export transactions with 27 EU member countries.In addition to these agreements, Vietnam has established various trade agreements and comprehensive economic partnerships with countries and regions such as the Economic Cooperation Organization, the United Kingdom, South Korea, Japan, Chile,... These agreements not only provide tariff advantages for Vietnamese steel but also create opportunities for price competition, benefiting both sellers and buyers by ensuring reasonable product prices.Flexible strategy in response to anti-dumping investigationsThe steel industry is considered a key industrial sector for many countries and numerous markets have sought to protect domestic steel products through various protective measures such as tariff barriers and anti-dumping duties. Vietnam, as one of the fastest-growing steel markets globally, has attracted attention from other countries, leading to anti-dumping investigations. However, most anti-dumping cases related to Vietnamese steel products are currently in the form of investigations due to suspicions regarding the origin of raw materials originating from China.Through flexibility and timely adjustments in export strategies, Vietnam has maintained its status as an ideal destination for steel importers. Diversifying markets and adapting quickly to international trade regulations have helped minimize risks associated with dependency on a specific market and legal issues, providing favorable conditions for positioning Vietnamese steel on the international market.Large-capacity factories equipped with modern production linesThe Vietnamese steel market has witnessed the emergence of many large-capacity manufacturing plants with substantial investments in advanced technology from the world's leading Danieli-Tenova technology. These plants not only meet domestic demand but also have the capacity to export to international markets. Notable examples include Hoa Sen, Hoa Phat, Nam Kim, Ton Dong A, T么n Ph瓢啤ng Nam - SSSC, SMC, Vina One Steel,...Hoa Sen Group leads in coated steel in Vietnam with a pickling capacity of 1.9 million tons per year and a NOF line capacity of 2.2 million tons per year.
