A588 Gr.K Weathering Steel Plate

A588 Gr.K corten steel plate is becoming more popular by roll formed product end-users. Its unique look and naturally oxidizing finish makes it especially desirable for many architectural projects. The steel has increased resistance to atmospheric corrosion when compared to other steels. It resists the corrosive effects rain, snow, ice, fog, and other meteorological conditions by forming a coating dark brown oxidation over the metal, which inhibits deeper penetration and saves the cost for painting or rust-prevention maintenance.

A588GrA steel plate application range

A588GrA, A588GrB, A588GrK are used for welding, riveting and bolting structures, but are mainly used for welded bridges and buildings that require weight reduction or extended life. This steel has significantly better atmospheric corrosion resistance than copper-containing or copper-free carbon structural steel under most environmental conditions. When fully exposed to the atmosphere, this steel is suitable for many occasions in the bare (uncoated) state.
