ASTM A588 structural steel plates are low alloy high strength structural steel. ASTM A588 structural steel plates have better atmospheric corrosion resistance in most environments than carbon structural steels with or without copper addition. When properly exposed to the atmosphere, ASTM A588 structural steel plates are suitable for many applications in the bare or unpainted condition. ASTM A588 steel grades are A588 grade A, A588 grade B, A588 grade C, A588 grade K.

ASTM A588 structural steel plates are limited up to 8 in. [200
mm] inclusive in thickness. ASTM A588 structural steel plates are
mainly for welded, riveted, or bolted construction. They are
intended primarily for use in welded bridges and buildings where
savings in weight or added durability are important.
