Product Description
Customized square tree protection metal tree grate

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".
