ASTM A513 is electric resistance welded and is made from 1010-1020 low carbon strip.
Relatively low in cost, structural tubing has a high strength-to-weight ratio and is easily welded, formed, punched and drilled. Its hollow shape protects and conceals wires, pipes, moving parts, etc.; and can be left exposed. This tubing can be subjected to most of the usual fabricating operations. Ductibility is good. Bends well, flattens, cuts, punches, flares, flanges and welds easily.
Light Structural Tubing is electric resistance welded, and is made from low carbon 1020 strip. The homogenous weld is as strong as the parent metal. Outside welding flash is removed on all sizes. Inside welding flash is controlled on all sizes under 2”. This economical tubing is readily formed, bent or swagged. It is excellent for applications where outside finish is important — for example when surface suitable for high gloss painting is needed.
