Textured Multipurpose 304 Stainless Steel Round Tubes

The textured surface hides fingerprints and dents. This material is widely used in decorative applications, such as partitions and handrails. 304 stainless steel is a good all-around choice that maintains its corrosion resistance in temperatures up to 1500° F.

Welded—These tubes are more economical than seamless tubes.
