ASTM A588GrA GrC weathering steel plate
Corrosion Resisting Structural Steel Products Description
A588 GrA corten material is for high strength low alloy structural steel with a minimum yield point of 345Mpa and a thickness of 100mm.
A588 GrC corten metal sheet is a high strength low alloy structural steel specification with improved atmospheric corrosion resistance for structural steel shapes such as angles, channels and beams, as well as steel plates and rebars.
A588 GrA corten sheet and A588 GrC atmospheric corrosion resistant steel are used for various types of welded, bolted and riveted structures such as steel frame structures, bridges, tanks and containers, exhaust systems, vehicles and equipment structures.
