Stainless steel square tube is a hollow long steel section, named as such because its cross-section is square. It is extensively used for piping that transmits fluids such as oil, natural gas, water, coal gas, steam, etc. Additionally, it is lighter in weight while maintaining equal bending and torsional strength, making it widely employed in the manufacturing of mechanical parts and engineering structures.

Stainless Steel Square Pipe Categories: Square pipes are divided into two main types: Seamless Steel Pipes and Welded Steel Pipes (Seamed Pipes). They can also be categorized by cross-sectional shape, such as square and rectangular pipes. Circular steel pipes are widely used, but there are also various shapes like semi-circular, hexagonal, equilateral triangular, and octagonal pipes.
