Why does A588 Grade A steel plate have corrosion resistance?

These A588 Grade A steel plate is designed primarily for unpainted applications to reduce maintenance costs, such as painting. Since its development, A588 Grade A steel plate has been widely used in bridges, railway vehicles, cranes, transmission towers, highway poles, chemical plants, factories and real medical shipbuilding and other fields.

A588 Grade A steel plate is resistant to atmospheric corrosion. Due to the formation of a protective oxide film on the metal surface, which slows down further corrosion, A588 Grade A steel plate has better corrosion resistance than ordinary carbon steel. At the same time, A588 Grade A steel plate is also a high-strength low alloy weathering steel with a minimum yield strength of 50000, which can reduce the cost by designing the lighter part into a structure.
