ASTM A709 Grade 50W is a standard specification for structural steel in bridges. ASTM A709 Grade 50W steel covers high strength, low allow steel structural shapes, plates and bars. The atmospheric corrosion resistance of this steel in most environments is substantially better than carbon steel with or without copper addition. ASTM A709 Grade 50W steel shall have an atmospheric corrosion index of 6.00 or higher.
