ASTM – A500 grade B and C is the standard specification for cold-formed carbon steel welded tube. Specifically, it’s hot rolled steel tubing with electric resistance weld (HREW). Commonly called H.S.S Tubes (Hollow Structural Steel).

Thanks to its high physical capacities and a very large variety of sizes, ASTM – A500 grade B and C H.S.S. tubes are used for structural purposes by our manufacturing customers in various fields of activity.

Available Dimensions

  • Round tubes of 0.840 ” to 20 ” outside diameter
  • Square tubes with external dimensions from
    0.500 ” x 0.500 ” to 22 ” x 22 ”
  • Rectangular tubes with external dimensions from 1.5 ” x 0.75 ” to 24 ” x 12 ”
  • Available thickness ranges from 0.100 ” to 0.750 ” depending on size
