Stockist & Producers of Weathering Steel A / EN S355 JOWP / ASTM A 242 TYPE 1
Weathering steel, best-known under the trademark Corten Steel A steel and sometimes written without the hyphen as "Corten steel", is a group of steel alloys which were developed to obviate
the need for painting, and form a stable rust-like appearance if exposed to the weather for several years. United States Steel Corporation (USS) holds the registered trademark on the name Weathering Steel A.
Although USS sold its discrete plate business to International Steel Group (now Arcelor-Mittal) in 2003, it still sells Weathering Steel A branded material in strip-mill plate and sheet forms. The original Corten
Steel A received the standard designation ASTM A 242 TYPE-1("Corten Steel A*") from the ASTM International standards group. Newer ASTM grades are A 588 ("Corten Steel A*") and A 606 for thin sheet. All alloys
are in common production and use.
