ASTM A588 steel plate
ASTM A588 steel plate is a high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction.The atmospheric corrosion resistance of this steel in most environments is substantially better than that of carbon structural steels with or without copper addition. When properly exposed to the atmosphere, this steel is suitable for many applications in the bare (unpainted)

Application
Compared with ASTM A36 and ASTM A572-50 carbon steel, ASTM A588 steel plate have better cossrosion resistant characteristic. Use ASTM A588 steel plate instead of common carbon steel which make the structure lighter for it has higher strength. ASTM A588 steel plate has many application fields: outdoor sculptures, crane, bridges, rail cars, transmission towers, highway poles and shipbuilding.
