📋 Product Description

Stainless steel square/rectangular tube is a kind of hollow long steel, widely used as a pipeline to transport fluids such as petroleum, natural gas, water, gas, steam, etc. Additionally, due to its bending and torsion strength combined with lighter weight, it is extensively used in manufacturing mechanical parts and engineering structures.

Classification: Available as seamless steel pipe (made via piercing, hot rolling, or cold drawing) and welded steel pipe (rolled from steel plate or strip). All pipes undergo strict hydraulic testing to ensure pressure resistance and quality.
