Stainless steel rectangular tube/square tube is a kind of hollow long steel,which is widely used as pipelines for conveying fluids, such as oil, natural gas, water, gas, steam, etc. In addition, when the bending and torsion strength are the same, the weight is relatively low. It is light, so it is also widely used in the manufacture of mechanical parts and engineering structures.
