ASTM A588 steel plate corrosion-resistant structural steel plate

ASTM A588 steel plate is well known for its weathering ability. When exposed to external conditions, its corrosion-resistant properties become stronger, even when unpainted. ASTM A588 steel plate has four times as much corrosion resistance as carbon steel. The ASTM A588 steel plate specification is to 50 ksi minimum yield point, with atmospheric corrosion resistance for applications where strength and durability are needed. The ASTM A588 steel plate include the Grade A, Grade B, Grade C, Grade K.
