ASTM International’s committee on steel, stainless steel, and related alloys (A01) is creating a specification for a new kind of high-grade, lightweight steel tubes used in construction of bridges, buildings, and more.

Specifically, the standard is for cold-formed welded high-strength carbon steel or low-alloy steel hollow structural sections (HSS). These can be used for welded, riveted, or bolted construction.

HSS includes higher grades of steel that are lighter in weight as well as stronger and more durable, according to ASTM International member Julie Childress, marketing manager at Bull Moose Industries.

This standard (WK41589) provides technical information and tolerance requirements for these newer grades of steel. This standard contains Grade 70, Grade 80, Grade 90, Grade 100, and Grade 110. Yield strengths that are not found in any current ASTM standard for hollow structural sections (HSS).

ASTM welcomes participation in the development of its standards. Become a member at The next meeting of the committee on steel, stainless steel, and related alloys is on November 5-8 at the Washington Hilton in Washington, D.C., (USA).
