ASTM A500 is a standard specification published by the ASTM standard for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. It is commonly specified in the USA for hollow structural sections. ASTM A500 defines four grades of carbon steel based primarily on mechanical property. Our tubing can meet both spec grade B and C.

Hollow Structural Sections (HSS) are manufactured hollow steel sections, typically of circular, rectangular, or square cross-section. In the United States, HSS sections conform to either the ASTM Specification A500 or A1085.
The use of HSS is growing with popularity all around the world in the building industry and in the United States accounts for approximately 18% of the structural steel market. Popular uses include architecturally exposed structural steel, staggered truss and conventional truss structures, and basic column or vertical bracing elements.
In 2013 a new ASTM specification for HSS was released, ASTM A1085. The new specification provides improved performance that makes HSS design easier and potentially more effective for the client. A quick comparison between A500 and A1085 can be found in the summary flyer.
