ASTM A283 is a carbon steel coil used for general structural purposes. The steel has low and medium tensile strength. The ASTM A283 steel specification covers four structural quality grades of mild steel, grades A, B, C, and D, for general application.

ASTM A572 carbon steel low-alloy steel is widely used as bridge panels, support plates, mechanical mounting plates, etc. for construction equipment, transmission towers, racks and other equipment.

ASTM A633 steel includes four grades: A, C, D, and E, of which the thickness of grade C can reach 4 inches and the thickness of grade E can reach 6 inches. ASTM A633 steel specification is based on the standard specification for standardized high-strength low-alloy structural steel plate, which requires high notch toughness under low temperature conditions.
