10 Leading GB Corten Steel Plate Suppliers in China 2026

Introduction to GB Corten Steel Plate

GB Corten Steel Plate, also known as weathering steel plate, is a type of high – strength low – alloy steel in line with Chinese national standards (GB). It offers excellent atmospheric corrosion resistance due to the formation of a dense and adherent rust layer on its surface when exposed to the environment. This rust layer acts as a protective barrier, significantly reducing the rate of further corrosion compared to ordinary carbon steels. GB Corten Steel Plate is widely used in various industries such as construction, bridge building, and container manufacturing, where long – term durability and resistance to harsh weather conditions are required.
