Square tube is a hollow square section light thin-walled steel pipe, also known as steel cold bending section. It is made of Q235 hot-rolled or cold-rolled strip or coil as the base material, which is formed by cold bending and then high-frequency welding. In addition to the thickening of the wall thickness of the hot-rolled extra-thick-walled square tube, its corner size and edge straightness have reached or even exceeded the level of the resistance-welded cold-formed square tube. It has good comprehensive mechanical properties, good weldability, cold and hot working properties and corrosion resistance, and has good low temperature toughness.The uses of square tubes include construction, machinery manufacturing, steel construction and other projects, shipbuilding, solar power brackets, steel structure engineering, power engineering, power plants, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, boiler construction, highway railings, Housing construction, pressure vessels, oil storage tanks, bridges, power station equipment, lifting and transportation machinery and other welded structural parts with higher loads, etc.
