MATERIAL — COR-TEN® STEEL

Steel that
protects itself.

Weathering steel — officially Cor-Ten® — is a special alloy with added copper, phosphorus and chromium. When exposed to the weather, it develops a protective patina: a stabilised rust-coloured layer that prevents further corrosion.

No painting. No galvanising. The material takes care of itself and grows more beautiful over the years.

Lifespan

Longer than ordinary steel without protective coatings.

0
Maintenance

No painting, no galvanising. The material protects itself.

Weathering steel (Cor-Ten®) develops a protective patina when exposed to the atmosphere. This layer prevents corrosion and extends lifespan by 4–8× compared to ordinary steel.

The patina stabilises within 1 to 3 years. In the early phase the colour is light orange, gradually darkening to deep brown.

Weathering steel is practically maintenance-free. It needs only occasional inspection and cleaning. No painting required.

Facades, railings, gates, planters, pergolas, sculptures, bridges and industrial structures. Popular in architecture and landscape design.

Smaller projects are typically completed within 2–3 weeks. For larger projects we set the timeline together during design.

Yes — most of our projects are bespoke. Send us a sketch or your idea and we'll develop a solution together.
