A588 Alloy Structural Steel Plate
ASTM A588 steel is a high-strength low-alloy structural steel section, steel plate and bar used for welded, riveted or bolted structures. These steels are mainly used in welded bridges and buildings where weight reduction or increased durability is required. In most environments, the atmospheric corrosion resistance of this steel is significantly better than that of carbon structural steel with or without the addition of copper.
