Rectangular tube is a hollow square section of light thin-walled steel pipe, also known as steel refrigeration bending profile. It is Q235 hot-rolled or cold-rolled strip or coil as the base material by cold bending process forming and then high-frequency welding made of square cross-sectional shape size of the section. In the same flexural and torsional strength, lighter weight, so it is widely used in the manufacture of mechanical parts and engineering structures.
