Introduction to JIS Corten Steel
JIS Corten Steel, also known as weathering steel, is a high – strength, low – alloy steel that forms a protective rust – like appearance when exposed to the elements. It is standardized according to the Japanese Industrial Standards (JIS). This type of steel has excellent corrosion resistance, which reduces the need for painting and maintenance over time. It is widely used in various applications such as bridges, buildings, railway wagons, and outdoor sculptures. The unique patina that develops on its surface not only provides protection but also adds an aesthetically pleasing look to the structures made from it. JIS Corten Steel
