Product Description

Stainless steel square tube is a long, hollow steel section named for its square cross-section. It is typically manufactured by cold-forming a stainless steel strip into a square shape and then welding the seam using high-frequency welding, or produced through a seamless cold-drawing process. Combining the excellent corrosion resistance and aesthetics of stainless steel with the structural strength of a square tube, it is a metal product widely used in construction, machinery manufacturing, decorative ornamentation, and other fields.

Production Process

The production process for stainless steel square tubes is mainly divided into two categories: Welded Tube Process and Seamless Tube Process. The welded process is the most common and economical method for producing square sections, while the seamless process is used for applications requiring extremely high pressure resistance and uniformity.
