S235JR, S275JR, and S355JR are all structural steel grades in the European standard (EN10025). After being galvanized into steel pipes, they have the characteristics of structural steel itself and the anti-corrosion advantages brought by the galvanized layer.
A500 Grade B, C, D Galvanized Steel Pipe is a high-quality square tube produced according to the American Standards Association (ASTM) A500 standard and is widely used in building structures, machinery manufacturing and other fields.
Hot dipped zinc steel pipe tube is a specially treated steel pipe with a uniform zinc layer on its surface. This treatment method usually involves immersing the steel pipe in molten zinc liquid, allowing the zinc liquid to penetrate the surface of the steel pipe and form a strong bonding layer. This process not only improves the corrosion resistance of the steel pipe, but also enhances its aesthetics and durability. Hot-dip galvanized steel pipe is widely used in various industrial fields, such as construction, oil, gas, chemical industry, etc.
Hot-dip galvanized steel pipe is a product that immerses the processed steel pipe into molten zinc liquid to attach a layer of zinc to the surface of the steel pipe. In terms of appearance, the surface of the steel pipe presents a uniform silver metallic luster, and the zinc layer is tightly combined with the steel pipe matrix. According to different usage requirements, the specifications of steel pipes are diverse, including different outer diameters, wall thicknesses and lengths. For example, common specifications include an outer diameter of 48.3mm. In terms of material, carbon steel and other materials are usually used as the basic pipe, and after hot-dip galvanizing, its performance is further improved.
There are many pipe diameters to choose from, such as 4 inches (about 101.6mm), 3 inches (about 76.2mm), etc., and the outer diameter ranges from 6 to 1240mm. The thickness is generally between 1 and 200mm, and different thicknesses can meet different usage requirements. Common lengths include 3m, etc., and the length can also be customized according to specific circumstances.
These steel pipes theoretically inherit the characteristics of steel under the ASTM A500 standard, can withstand high impact, have good compressive resistance, and ensure safety in various harsh environments and high load conditions. They have excellent durability, are made of solid metal, and use processes such as hot rolling or cold drawing to ensure their long service life and long-term stable use.
