U-channel Steel

Square pipe is a hollow square cross-section of light thin-wall steel pipe, also known as steel cooling curved profile. It is made of Q235 hot rolled or cold rolled strip or coil as the base material by cold bending processing and then high frequency welding made of square section shape and 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 special thick wall square pipe reach or even exceed the level of the resistance welding cold formed square pipe. Good comprehensive mechanical properties, weldability, cold and hot processing properties and corrosion resistance, with good low temperature toughness.
