ASTM BS DIN GB JIS Low Carbon Seamless Welded Square MS Steel Pipe
Product Description
The welded square tube is a hollow square section steel square tube, also known as a hollow cold-formed steel. The utility model relates to a profiled steel of a square cross-sectional shape which is formed by hot-rolling or cold-rolling strip or coil as a blank after cold bending forming and then high-frequency welding. In addition to the thickening of the wall thickness of the seamless square tube, the corner size and the straightness of the edge meet or exceed the level of the cold-formed square tube of the electric resistance welding.
