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.

What is galvanized steel pipe used for? Let's explore these applications in agriculture, solar energy, oil industry, construction and more with AG真人游戏 Steel!Galvanized steel pipe has been coated with zinc to protect the steel from corrosion. GI is most commonly used for outdoor construction such as fencing, handrails and interior plumbing applications (plumbing, fire fighting systems,鈥�). AG真人游戏 Steel will dive deeper into the issue of 鈥渨hat is galvanized steel pipe used for鈥�.What is galvanized steel pipe used for? Explore now with AG真人游戏 SteelWhat is galvanized steel pipeGalvanized steel pipes are hollow, thin-walled steel structures with good load-bearing capacity and minimal impact from environmental factors. The addition of an external zinc coating further enhances their resistance to rust formation, oxidation and environmental influences such as climate, temperature, humidity,...Galvanized steel is divided into hot-dip galvanizing and electroplating with different characteristics and pros and cons:Hot dipped galvanized steel pipeHot-dip galvanizing is the traditional method of coating steel pipes with a protective layer. Surface-treated steel pipes are dipped into a tank of molten zinc. The zinc layer is evenly coated on both sides, with good rust resistance, adhesion and long life expectancy. GI's zinc coating is usually about 50 micrometers thick on average.Electrolytic galvanized steel pipeElectrolytic galvanizing, also known as cold galvanizing, only uses a very small amount of zinc, about 10-50g/m2 to coat the outer surface of various products. Electrolytic plating technology creates a precipitate on the metal layer, so the corrosion resistance is much worse than that of hot-dip galvanized steel. Products cold-plated have low cost, high adhesion, and low deformation at high temperatures.Galvanized steel pipes offer strength, rust resistance and versatility for construction needsGalvanized steel pipe classificationRound steel pipes: mainly used for water pipes, lamp posts, railings, stair handrails, ultrasonic piles,...Square and rectangular steel pipe: depending on the thickness of the steel pipe, it will be used as a roof frame, scaffolding or in the manufacture of furniture, motor vehicle parts, ...Oval steel pipe: this type of galvanized steel pipe is widely used in the field of furniture, frames鈥檚 car, motorcycles, bicycles,...What is galvanized steel pipe used for?Galvanized steel pipes have many outstanding features such as high aesthetics, comprehensive protection, good life expectancy, ... when applied to projects and fields of life.Applications in solar energySolar panels have a large mass of 20-24kg to ensure that the system is not affected by the effects of storms or high winds. Therefore, the support frame needs to be strong, capable of withstanding large loads and wind levels of 10, level 12 in stormy weather. In addition, the frames that support the solar system are placed outside and are often affected by the weather, so they must resist corrosion.In almost all materials, galvanized steel can meet all of the above requirements thanks to its stable, solid, high-strength, load-bearing and good-bearing structure. The zinc coating on the outside of the steel pipes has a comprehensive protection effect, increasing the long term use of the frame system. Therefore, galvanized steel, especially pipe steel, box steel, V-shaped steel,..., are often chosen as frames for solar power systems.Galvanized steel ensures durable and corrosion-resistant frames for solar power systemsApplication in agricultureGalvanized steel pipe has good rust resistance, variety of sizes, easy to shape and install, so it is widely used in irrigation systems.Black steel pipes, hot-dip galvanized steel pipes are also widely used in animal husbandry.
