Shanghai square tube plant, Shanghai Hao iron square tube 250 * 250 * 4 low-alloy square tube

Shanghai square tube plant, Shanghai 250 * 250 * 4 low-alloy square tube square iron Holdfound Tubing As the name suggests, it is a kind of square shape of the tube, a variety of material substance can form a square tube, it is the medium in, what for , used in any place, most of the pipe to steel pipe for the majority, after unpacking, smooth, curl, tube welding is formed, and then cut to the desired length and then rolled into the square from the round tube. Square tube is a thin-walled hollow square cross-section of light pipe, also known as cold-formed steel profiles. It is a square cross-sectional shape and size Q235 steel hot-rolled or cold-rolled strip or coil of the base material after the cold bending molding made by high-frequency welding. Hot-rolled special thick-walled square tube wall thickness thickening of the outer case except that the corner sizing and edge flatness meet or exceed the resistance welding cold forming square tube level. Good mechanical properties, weldability, cold, heat processing performance and corrosion resistance are good, with good low temperature toughness. Square tube uses include construction, machinery manufacturing, iron and steel construction projects, shipbuilding, solar stent, steel structure engineering, electrical engineering, power plants, agricultural and chemical machinery, glass walls, car chassis, airports, boiler construction, highway railings, Housing construction, pressure vessels, oil storage tanks, bridges, power station equipment, material handling equipment and other welded structure of high load and so on. Professional management of high precision large diameter square tube rectangular tube (straight seam, seamless), size 100 x100-500x500 wall thickness of 3 mm-25 mm, material: Q235B, Q345D, 20 steel, 16Mn stainless steel. Mainly used in machinery manufacturing, steel, shipbuilding, military products.
