COR-TEN A

Atmospheric corrosion resistant plates and sheets

COR-TEN A is a strip mill product. The chemical composition of COR-TEN A has been designed to provide a relative resistance against atmospheric corrosion, in particular for urban environments. It can therefore be used even without painting; in this case a thin layer of stable oxides will be formed, thus preventing further corrosion inside.

Reference standards

COR-TEN A steel plates comply to the following standards: NF A 35‑502‑E36W, ASTM A242 and A588, EN 10155‑Fe510A1K1/DD2K1, S.E.W087, S335 POW.

Fields of application

The mechanical characteristics and the resistance against atmospheric corrosion make this steel the best product for the fabrication of agricultural vehicles and railway wagons, bridges, water pipes, fans, chimneys and boilers and outdoor sculptures.
