Weathering Steel (CORTEN)

Weathering Steel, often referred to as Cor-ten or A588/606, is a unique material popular for its distinctive rust patina. This natural yet stable protective coating acts as a defense against further corrosion. Weathering steel arrives unrusted and develops a rust-like appearance once exposed to the elements for a period of time.
