Cor-Ten Steel

Cor-Ten steel is a high tensile strength, corrosion resistant steel alloy which contains copper, chromium and phosphorous. The name Cor-Ten reflects the special properties of this alloy: corrosion resistance (Cor) and high tensile strength (Ten). These properties make Cor-Ten steel particularly suitable for use in any environment.

Transformation Process
The large rolls of Cor-Ten steel are cut to the required width and rolled to the specific profile section. Upon exposure to air, the patina process begins which creates a protective layer of rust over the surface. Left untreated, the rust will create an ever changing appearance. A surface wax treatment can be applied which will stop the continued rusting and will provide a protective barrier against the elements.

Cor Ten steel has a unique distinctive appearance. The intense richness of its finish bestows a warm, natural, yet at the same time extremely elegant look. Its attractive appearance is a result of an oxidation process which forms a protective patina that remains unchanged over the years. A hand applied wax treatment can be administered to achieve a smooth look.
