A588 grade B steel sheet is suitable for many applications in the unpainted condition. A588 grade B steel sheet is substantially better than that of carbon steels such as A36 and A572-50 with or without copper addition when properly exposed to the atmosphere.
A588 grade B steel sheet is a copper chromium alloy steel – this alloy displays a greater level of resistance to atmospheric weathering when compared to other unalloyed steels. Its chemical composition promotes the early formation of an adhering protective layer of rust when exposed to the elements.
