A588 series weathering steel,A588 GR(Grade A,Grade B,Grade C) steel

A588 series weathering steel bridge structures including A588GrA, A588GrB, A588GrC and so on. Compared with carbon-steel, A588GrA series of weathering steel in the atmosphere has better corrosion resistance.

A588 weathering steel main component is divided into the elements such as P, Cu, Cr, Mo, Nb, V, T, etc. total alloying elements accounts for only a few percent, and not as stainless steel to teens, so the price is relatively cheap.

A588 steel is suitable for many applications in the unpainted condition. The atmospheric corrosion resistance of A588 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.
