    Brushed #4

    Polished to either a brushed or mirror-like finish on the outside, this material is widely used to fabricate decorative enclosures and industrial workstations. 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—Often called a satin finish, it’s similar to a #3 finish, except the grain lines are finer.
    Seamless—These tubes are more corrosion resistant than welded tubes because they don’t have a seam that could potentially introduce impurities.
