The stainless steel square tube is a hollow, long strip of steel, which is called a square tube because of its square cross-section. Pipes that transport fluids, such as petroleum, natural gas, water, gas, steam, etc., are used in large quantities. In addition, they are lighter when they have the same bending and torsion strength, so they are also widely used in the manufacture of mechanical parts and engineering structures.

Applications includes trailers, barriers, bike racks, home construction and many more.
