Introduce
Corten steel, also known as weathering steel, corten steel is a combination of gold steels that can develop a stable rust-like appearance if exposed to weather. This tight rust appearance will prevent further corrosion of the weathering steel material.

Due to the addition of Cu, Ni, Cr and other alloying elements, weathering steel materials not only have excellent corrosion resistance, but also have advantages in ductility, molding, cutting, weldability, heat resistance, wear resistance and other aspects.
Specification
AHL CORTEN manufactures sheet, coil, tube and section weathering steel products to EN, JIS and ASTM standards. Ahl-corten steel comes in a variety of sizes and is the best choice for the pursuit of modern and rustic styles.

Here are some common grades of weathering steel plate, and some others are known for their high quality corrosion resistance and excellent appearance after corrosion. Such as TB 1979 in 09CUPcrni-a.

Services: pre-rust treatment, bending, cutting, welding, pressing, punching, on-demand design.

Why use corten steel?
1. Weathering steel with strong corrosion resistance is very suitable for outdoor environment;

2. Weathering steel has no maintenance cost, long service life and 100% recyclable;

3. The reddish brown rust layer makes the unique appearance of weathering steel perfectly blend into the space.
