ASTM A500 and A1085 HSS are cold-formed, welded carbon steel structural tubing products that offer excellent compression and torsional resistance.
ASTM A500, Grade C is the standard specification used in North America and is readily available from North American HSS producers as well as steel service centers.
ASTM A1085 HSS are higher performing and well suited for applications that demand more, such as seismic or bridge applications.

CSA G40.21 HSS are cold-formed, welded carbon steel structural tubing products produced to the Canadian steel standard. We offer Class C and Class H in accordance with this specification.
Class C HSS are cold-formed and welded similar to ASTM A500 HSS.
Class H HSS are also cold-formed and welded, but then heat-treated in a furnace to stress relieve the product. Class H can be designed to a higher axial capacity in accordance with CSA S16, which may lead to weight savings in column applications.

The largest HSS in North American can help you build bigger, wider and taller than ever before. See how Jumbo HSS are changing the structural steel game.
Not only is steel the strongest building material on Earth, it’s also the greenest. Atlas Tube structural steel includes steel made in electric arc furnaces that emit 75% less CO2 than traditional steelmaking. Each new HSS can contain up to 70% recycled content and is 100% recyclable.
