Rectangular tube is a kind of hollow square section of light thin-wall steel pipe, also known as steel cooling bent profile. It is Q235 hot rolled or cold rolled strip steel or coil as the base material after cold bending processing and then high frequency welding made of square section shape size of the section steel. In addition to the thickening of the wall, the corner size and the flatness of the edge of the hot rolled extra-thick wall square pipe reach or even exceed the level of the resistance welding cold-formed square pipe.
