Square tube is a hollow square section warp shaped thin-walled steel tube, also known as steel profile. It is a section steel with square section shape and size, which is made of Q235 hot milk or cold milk strip steel or coil plate as the base material, cold bending and forming, and then high-frequency welding. In addition to the thickening of the coil thickness, the corner size and edge flatness of the hot milk to be thick square tube reach or even exceed the level of resistance welding cold formed square tube. It has good comprehensive mechanical properties, weldability, cold and hot workability and corrosion resistance, and has good low-temperature shear resistance.

Used in automobile manufacturing, refrigeration box, construction industry, ventilation and heating facilities, furniture manufacturing and other fields. Zinc plating has become an important anti-corrosion method for iron and steel, not only because zinc can form a dense protective layer on the surface of iron and steel, but also because zinc has cathodic protection effect. When the galvanized layer is damaged, it can still prevent the corrosion of iron base material through cathodic protection.
