as a rule any rectangular tubing wider than 3" is structural tubing. Structural tubing conforms to astm a500 grade b. An electric resistance welded tube produced from a structural grade of steel. Offers a high strength-to-weight ratio, yet is easily welded, formed, punched, and drilled. All sizes have the od flash removed, with the id flash-in. Minimum mechanical properties: Tensile strength = 58,000 psi, yield strength = 46,000 psi, % elongation in 2" = 23%
tubing 3" and smaller is mechanical tubing and conforms to astm a513 type 1 (awhr) or type 2 (awcr). Mechanical tubing is an electric resistance welded tubing produced from low carbon steel. Offers good surface finish and forming characteristics. All sizes have the od flash removed, with the id flash-in. Generally available in wall thickness lighter than 11ga.
