Next, let's learn about hot rolled steel vs cold rolled steel.What is hot rolled steel?Hot rolled steel is a type of steel produced through a hot rolling process at high temperatures, often exceeding 1000掳C. This process can change the material and shape of the metal. Hot rolled steel products are often dark green, less shiny and lack aesthetics.Hot rolled steel are usually produced at high temperaturesWhat is cold rolled steel?Cold rolled steel is essentially a hot rolled steel that has been cooled and re-rolled at room temperature. After going through the process of gradually reducing the length of the cold rolled steel, it has appropriate dimensions and smooth surface quality. Because it goes through many processing processes, cold rolled steel often has a higher price than hot rolled steel, so product quality as well as aesthetics are also highly appreciated compared to hot rolled steel.Cold rolled steel has a smoother surface than hot rolled steelDifference between Hot-rolled and Cold-rolled steelTo distinguish between hot rolled and cold rolled steel, in addition to learning about the nature through the definition of each type of steel coil mentioned above, we need to differentiate through factors such as the normal thickness, price of each type, surface, and edge of the steel coil.

Steel is one of the most common materials in the world as it appears everywhere from skyscrapers to a presence in consumer goods daily. There have been some questions about whether the depletion of steel raw materials will occur, in fact, steel has an endless recycling capacity and manufacturers took advantage of 鈥渟teel recycling鈥� method to produce steel for a long time.The position of steel recycling in the eco-friendly manufacturing trendingEnvironmental protection has always been a top concerned topic when the climate is clearly changing, which has seriously affected the ecosystem. In addition to some measures preventing environmental waste such as limiting the use of plastic and not littering, the application of steel recycling is a solution that brings optimized cost along with saving resources.Steel recycling brings endless value to the economy because it is conservation and is a radical solution to wasting resources. Because steel has metallurgical properties, meaning that it can be melted and solidified later. Let's think about how millions of tons of scrap steel each year, instead of being discharged into the environment, are melted down to continue to be used for the manufacturing industry. According to statistics, steel is the most recycled building material in the world with about 40% of total steel production based on scrap recycling.The benefits that steel recycling brings to eco-friendly economySteel recycling creates an endless ring An interesting fact about steel is that they can be recycled consecutively without losing their inherent durable properties. The iron elements in steel cannot be destroyed, so the manufacturer will proceed to melt the steel and add some other alloying elements to create new steel products. Just like that, the life cycle of steel repeats continuously and helps many businesses optimize costs in exploiting materials for production.Saving energy & natural resourcesRecycling steel allows people to better protect natural resources as the energy used in recycled steel will be much less than making steel by blast furnace production. For each ton of recycled steel, 1 ton of iron ore and 600 kg of coal are saved. Moreover, the energy saved from steel recycling can be used for more than 18 million households in 1 year.Reduce wasteThanks to recycled steel, the area for landfill has been significantly reduced because scrap collection is the first process to be able to recycle steel. Every year, the world produces an average of 1 billion tons of steel and without recycling methods, the world's waste will have no place to be.Decreasing emissionsAccording to research, every 1 ton of steel produced from ore is equivalent to releasing 100 kg of dust and 10,000m3 of emissions to the environment because producing steel from ore requires a lot of coal and the ore itself contains only 50% of iron. Meanwhile, scrap steel contains up to 97% of iron, so recycling through scrap steel can significantly reduce emissions to the environment and help businesses save costs of input coal.Create more jobs and income for people: the steel recycling industry has been creating jobs for hundreds of thousands of people around the world by collecting scraps or conducting sorting in recycling plants .Thanks to that, the number of unemployed people will be reduced and social evils will be limited.Currently, Vietnam is also one of the countries that have policies on greening in production and more Vietnamese businesses have begun to pay attention to the promotion of recycling. For example, Hoa Phat has built a blast furnace slag recycling plant to produce cement, they also invested in a heat-to-electricity conversion line to prolong the added value chain, reduce waste treatment costs and protect the environment.Recycling steel is now considered a very viable option for the economy because it helps to conserve energy, supports businesses in proactively having available input materials when there is no need to exploit natural materials.

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.

Galvanized steel is one of the materials that are resistant to corrosion and good aesthetics should be used in many different industries and construction. One of the most popular types of galvanized steel is the Z350, featuring an outer protective layer providing a 'fence' against environmental factors. 1. What is Z350 galvanized steel?Galvanized steel is a type of steel coated with a layer of hot-dip zinc to enhance its outer surface. They are produced by hot-dip galvanizing at a temperature of 500oC or electroplating so that it corresponds to the desired thickness to increase the durability and aesthetics of the material.Z350 steel corresponds to a zinc coating with a mass of 350 grams/m2 on both sides of the steel. Its corrosion resistance and high durability make it suitable for construction, household appliances, transportation and various industries.2. Characteristics of Z350 galvanized steelThe construction industry and light industry account for about 30% of the need for galvanized demand, so you can easily see applications from Z350 steel in life. Why are they so popular and widely utilized?Corrosion resistanceGalvanization is one of the most effective and economical steel protection methods for preventing rust. Currently, half of the world's zinc production is used for this process. Zinc not only provides a thick protective layer on the steel surface but also protects the steel through cathodic protection. If using products under normal conditions, the lifespan of Z350 steel structures can exceed 50 years and in corrosive environments or near the sea, it can still last around 20-25 years or more.High hardnessThe outstanding hardness of Z350 steel provides outstanding load-bearing capacity. Even in transportation with impacts, it does not compromise the quality, structure or lifespan of the galvanized steel.Fast production process, easy inspection The process of producing Z350 steel is simple, easy to control quality, allowing factories to fulfill orders promptly.Cost optimizationThe cost of producing galvanized steel is quite optimal thanks to the cheap zinc coating, short galvanizing time, high durability, easy storage, ... resulting in long-term cost savings.3.

The barn is used for many purposes like protecting livestock, storing animal feed, agricultural products or machinery against the environmental elements. Currently, farm owners tend to use PPGI as a barn instead of wood or concrete because of many outstanding advantages.1. Characteristics of barns in agricultureIn the field of agriculture, warehouses are usually designed with 2 floors, the first floor is a shelter for animals or storage of production machinery and equipment. The 2nd floor area is used to store animal feed, agricultural products or other utensils.The barns are named according to the purpose of use, such as tobacco barn, dairy barn, farm barn, tractor barn. The most principal type in the United States is the multipurpose barn, used for housing horses, cows, calves, sheep or storing hay and grain.Wood is the main material in traditional barns, but since World War II, pre-painted galvanized is more increasingly used, especially in large farms because of the advantages of aesthetics, durability and costs.2. Building barn with PPGIWhen building a barn, the roof, door and insulation are essential components that are first considered. The materials that make up these parts of the warehouse will greatly affect the effectiveness of protecting livestock, agricultural products and machinery from the effects of the environment and weather.2.1. RoofThe roof is one of the most important components of the barn because of its role of creating shade, shading the sun and rain and keeping the interior temperature. Most roofs today are constructed from PPGI sheets. With a high-grade coating that does not peel, is durable over time, has the ability to block heat to help keep the interior space cool and temperature stable. Compared to shingles that need to be re-glued every 12-15 years or the wood is prone to rotting, pre-painted galvanized sheets have a long life expectancy, are extremely water and corrosion resistant.2.2. Barn doorThe barn door should be easy to open and to secure. When the weather is favorable, the doors can be fully opened to ventilate the interior space, enhancing the exchange of fresh air for the animals to breathe. The PPGI barn door is very light, easily slides on the rail, saving you time and effort when opening and closing the door.2.3. Thermal and soundproof partition wallsWood, concrete and brick are good insulators but have poor sound insulation. Animals such as horses, cows, sheep,... are very sensitive to sounds, easily panic and lose control in noisy environments. Therefore, ranchers are gradually turning to PPGI to make soundproof walls for different types of barns.3. Advantages of PPGI barn 3.1. Moisture ResistanceHumidity and severe weather can affect the structural integrity of the barn. Wood is porous, absorbent and prone to decay over time while galvanized steel is more resistant to water, rust and corrosion.3.2. Longer lifespanWith wooden barns easily damaged by insects and birds, causing termites or nesting on the rafters. Steel buildings can limit these problems as well as avoid degradation due to burrowing insects.3.3. Fire ResistanceThe surface of PPGI is covered with special fireproof layers to help steel frame buildings have high fire resistance, slow down the spread of fire. Types of barns in foreign countries need to pay insurance levels in case of fire and explosion. Therefore, although wooden warehouses are lower in cost, in the long run, steel buildings have better insurance costs which helps to optimize overall costs.3.4. Strength and durabilityPPGI sheets are durable, withstand heavy loads but are lighter than many other building materials. The barns made from steel are 30-50% lighter than wood. This helps the construction of steel frames and building details save more time and manpower than traditional materials.4.
