Description

Square tube is a hollow square cross-section light thin-walled steel tube, also known as steel cold-bent profile. It is a square cross-section steel 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, the corner size and edge straightness of the hot-rolled extra-thick-walled square tube reach or even exceed the level of the resistance-welded cold-formed square tube. It has good comprehensive mechanical properties, good weldability, cold and hot processing performance and corrosion resistance, and good low-temperature toughness.

Square tube uses

Square tubes are used in projects such as construction, machinery manufacturing, steel construction, shipbuilding, solar power generation brackets, steel structure engineering, power engineering, power plants, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, boiler construction, highway railings, house construction, pressure vessels, oil storage tanks, bridges, power station equipment, lifting and transportation machinery and other high-load welded structural parts.
