Polished Multipurpose 304 Stainless Steel
Polished to either a brushed or mirror-like finish, this material is widely used to fabricate decorative enclosures and industrial workstations. The sheets, strips, bars, and adhesive-back foil are covered with a protective peel-off film. 304 stainless steel is a good all-around choice for a wide range of applications. It maintains its corrosion resistance in temperatures up to 1500° F.
Brushed #4 is often called a satin finish; it’s similar to a #3 finish, except the grain lines are finer. Rectangular and round tubes are polished on the outside.
