    The square tube is a hollow square cross-section light thin-walled steel tube, also known as steel refrigerated bending section. It is a section steel with a square cross-sectional shape and size 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. Except for the increased wall thickness, the corner size and edge flatness of the hot-rolled extra-thick-walled square tube reach or exceed the level of the resistance welded cold-formed square tube. Good comprehensive mechanical properties, good weldability, cold and hot workability and corrosion resistance, and good low-temperature toughness.

    The square tube is used for construction, machinery manufacturing, steel construction and other projects, shipbuilding, solar power support, steel structure engineering, power engineering, power plants, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, boiler construction, highway railings.

    There are also housing construction, pressure vessels, oil storage tanks, bridges, power station equipment, lifting and transportation machinery and other higher-load welded structural parts.
