COR–TEN® is a weather resistant steel that is suitable to work in multiple corrosive environments. Its carefully selected chemical content as well as the production process allow it to withstand different environmental impacts. During wet and dry cycles COR–TEN® will protect itself with copper oxides which will form a patina layer on the steel’s surface. That way patina blocks or even slows further corrosion. COR–TEN® steel works very well with sulfur oxides and is not suited for submerged applications where there is no oxygen access. Typical applications for COR–TEN® steels are building facades, pipelines, chimney and ventilation shafts as well as heavy-duty transport.
