Overview

Also called COR-TEN/CORTEN/Corten, this is a unique steel alloy. When exposed to the outdoor environment, this material quickly develops an orange-brown rust-colored sheen that actually protects the material underneath it. Additionally, A588 steel exhibits high strength but is 20-30% lighter than comparable alloy steels. It is weldable, formable, and easily machinable. It is frequently used in industrial applications, freight cars, and decorative applications.
