ASTM Tube Specification
Our HSS SuperStruct square, rectangle and custom-shaped tubes conform to the standards set out by the ASTM International's Specification A1065 - Cold Formed Electric-Fusion (Arc) Welded High Strength Low Alloy (HSLA) Structural Tubing in Shapes. For more detailed information about ASTM A1065 and standard tolerances, such as wall thickness, length, straightness, squareness of sides, twist and corner radius, please click here.
