This guide covers standard specification for round, square, rectangular, and special shape, electric-resistance-
welded mechanical tubing, either zinc-coated (galvanized) after welding or produced from aluminum-coated, zinc-coated (galvanized), zinc-iron alloy-coated (galvannealed), or aluminum-zinc alloy-coated steel sheet. Low-carbon steels and other carbon steels shall conform to the required chemical composition for carbon, manganese, phosphorus, and sulfur. The steels shall conform to elemental tolerances for product analysis. Wall thickness tolerances for premetallic coated as-welded tubing and diameter tolerances for metallic-coated round tubing shall be provided.
