Carbon Steel Rectangular Pipes
Rectangular tube is a hollow square cross-section lightweight thin-walled steel tube, also known as steel cold-formed profile. It is a square section steel with a square cross-section shape and size made of Q235 hot-rolled or cold-rolled strip or coil as the base material, cold bending and then high-frequency welding. In addition to the thickening of the wall thickness, the corner size and edge straightness of hot-rolled extra thick-walled square tubes reach or even exceed the level of resistance welded cold-formed square tubes.
Classification of rectangular pipes: Steel pipes are divided into seamless steel pipes and welded steel pipes (seamed pipes), hot-rolled seamless square pipes, cold-drawn seamless square pipes, extruded seamless square pipes, and welded square pipes.
