A588 Gr.B structural steel plate for welding bridges

A588 Gr.B material is a high-strength low-alloy structural steel suitable for welding, riveting or bolting. It is mainly used for welding bridges and buildings. A588 Gr.B structural steel plate is very important to reduce weight or increase durability. In most environments, the atmoSPHEric corrosion resistance of this steel is much better than that of carbon structural steel with or without copper.

Chemical composition

A588 Gr.B mechanical properties

A588GrA, A588GrB, and A588GrK structural steel plates are used for welding, riveting and bolting structures, but they are mainly used for welding bridges and buildings that require weight reduction or longer life. This kind of steel has significantly better atmospheric corrosion resistance under most environmental conditions than carbon structural steels with or without copper. When completely exposed to the atmosphere, this A588 Gr.B structural steel is suitable for many occasions in the bare (uncoated) state.
