Corten A steel sheet with strong corrosion resistance

Corten A steel sheet is weatherproof high strength steel that overcomes the weakness of steel corrosion through a unique way of rust and rust protection. Corten A steel sheet was exposed to the atmosphere and rusted at first as normal steel. Because of this good performance, Corten A steel sheet can be used without painting, so it can be said that Corten A steel sheet breaks through the traditional understanding that steel must be painted.

Corten A steel sheet exposed to the atmosphere, the initial rust layer, like ordinary steel, but with the extension of time the rust layer gradually becomes dense, becoming a close rust layer on the base metal (protective rust layer). The rust layer protects the base metal and inhibits the continuous corrosion of the base metal. The corrosion of Corten A steel sheet has been restrained after 3-5 years of exposure in industrial areas. The experimental results from coastal areas are analyzed.

Compared with ordinary steel, Corten A steel sheet has less corrosion, but after a long time, Corten A steel sheet corrosion is also in progress. This requires special attention when using Corten A steel sheet in coastal areas.
