🔧 Product Introduction
Stainless steel square tubes are hollow long strips of steel. Due to their square cross-section, they are called square tubes. They are widely used as pipelines for transporting fluids, such as oil, natural gas, water, gas, steam, etc. Additionally, when the bending and torsion strength are the same, they are lighter in weight, so they are also widely used in manufacturing mechanical parts and engineering structures.
