Its surface initially rusts, but as a protective layer forms, the corrosion process slows down. This results in a stable, distinctive rust-brown patina that is considered a key design feature.

This protective layer prevents further corrosion, eliminating the need for additional corrosion protection. Thanks to this passivating layer, Corten steel is resistant to many environmental conditions, especially outdoor humidity.

The Corten steel grating opens up new design possibilities through its aesthetics and technical properties.

Metal oxidation is complete after one to three years. The patina of each Corten-Stahlgitterrostes is unique at the end of this process!

The rust-coloured look combined with high weather resistance makes this grating a popular feature in Architecture, Urban Furniture, landscaping, construction and art – above all for outdoor sculptures.
