ASTM A588 Weathering Steel Plate

ASTM A588 Weathering Steel Plate

ASTM A588 specifies high strength low alloy weathering steel for structural purposes, it includes 4 grades: Grade A, Grade B, Grade C, Grade K. For it has protective oxide film on steel surface, compared with ASTM A36 and ASTM A572-50, it has better cossrosion resistant characteristic, use ASTM A588 steel plate instead of common carbon steel will make the structure lighter for it has higher strength. It has many application fields: outdoor sculptures, crane, bridges, rail cars, transmission towers, highway poles and shipbuilding. AGICO-ANSON specializes in weathering steel plate, with years of project experience, we supply high quality ASTM A588 steel plate with best service.
