High strength, low alloy, weldable structural steel - Steel that protects itself
Cor-ten is a high strength, low alloy, weldable structural steel possessing excellent weathering resistance. It may be used to advantage in painted or unpainted condition. The steel owes its weathering resistance to the formation of a protective oxide coating which seals the surface against further corrosion. The coating is of a dark brown appearance and if chipped or damaged, repairs itself to give continuity of protection and appearance.
Improved weathering properties
Cor-ten is recommended for use where high structural strength is needed and where maintenance is difficult. With mechanical properties similar to conventional steels, Cor-ten can be used to construct lighter structures utilising well-established design practices but with the advantage of improved weathering properties.
- Develops its own protective film which slows the rate of corrosion.
- Saves the cost of initial painting and the maintenance costs of repainting.
- Gives corrosion protection to unpainted areas which have been damaged. Painted areas which have been damaged will weather to form a protective film; this will extend to the edges of those areas and reduce under-paint corrosion ‘creep’.
