Corten steel

Corten steel is a material that evolves over time, with its transformation process varying according to environmental conditions. It is prized for its ability to naturally patinate, giving it great resistance to weathering. Color variations observed may result from exposure to light and humidity. We supply unoxidized or partially oxidized products, and full maturity or passivation may not be achieved initially. These variations in appearance are particularly visible on parts that have undergone bending or welding, where patina formation is accelerated. Thus, significant color differences may be observed between products from the same batch or different surfaces of the same product.

02

Corten transformation factors

The formation, adhesion and porosity of patina on Corten steel are influenced by its composition as well as various local climatic factors, such as temperature, humidity, wind, precipitation and initial exposure time.

03

Oxidation

During the patina process, an essential step is the removal of oxides generated by corrosion. This removal is aided by rainwater runoff, which dissolves some of these oxides, creating streaks that can stain porous surfaces. It is therefore recommended to avoid placing items on light-colored floors or to opt for suitable protection.
