What is A588 Gr C Weather Resistant Steel?

ASTM A588 Gr.C is a high-strength, low-alloy structural steel grade with enhanced atmospheric corrosion resistance. It is used for structural steel shapes such as angles, channels, and beams, as well as steel plates and bars. A588 Gr.C is primarily intended for welded bridges and other structures where weight reduction, increased durability, and an extended life cycle are important due to its corrosion-resistant properties.

A588 Gr C Steel Application

The atmospheric corrosion resistance of A588 Gr. C steel in most environments is substantially better than that of carbon structural steels with or without copper addition. When properly exposed to the atmosphere, A588 Gr.C steel is suitable for many applications in the bare (unpainted) condition.ASTM A588 Gr.C Atmospheric Corrosion Resistant Steel is used for various types of welded, bolted and riveted constructions e.g. steel frame structures, bridges, tanks and containers, exhaust systems, vehicles and equipment constructions.
