Weathering steel, best-known under the trademark COR-TEN steel and sometimes written without the hyphen as corten steel, is a group of steel alloys which were developed to eliminate the need for painting, and form a stable rust-like appearance if exposed to the weather for several years. The name is short for "corrosion resistance" and "tensile strength".

Weathering refers to the chemical composition of these steels, allowing them to exhibit increased resistance to atmospheric corrosion compared to other steels. This is because the steel forms a protective layer on its surface under the influence of the weather.

The mechanical properties of weathering steels depend on which alloy and how thick the material is.

AHL Company is professionally in supply corten steel sheets and final finished corten steel products through cutting, bending, welding and profiling. And pre-rusted treatment for the corten steel products is our unique technology, the advantages as below:

Efficiency---- taking shorter time to develop the rust layer
Pro-environment---- no rust liquid dropping and rust slag flying
