Corten Steel: The Beauty of Noble Rust
Corten is a self-patinating steel that develops a protective rust layer on its surface. This unique ochre-orange colour deepens over time, enhancing its aesthetic appeal.
Steel That Grows More Beautiful with Age
Corten (CORrosion TENsile) is an alloy of steel, chromium, and phosphorus that oxidises on its surface to form a stable oxide layer. This natural patina protects the steel from atmospheric corrosion, eliminating the need for painting. Used in architecture since the 1960s, it is now a star material in contemporary design.
Recommended Uses for Corten Steel
- — Gates and Wicket Gates
- — Planters and Edging
- — Facades and Cladding
- — Privacy Screens and Louvers
- — Fire Pits and Outdoor Fireplaces
Important Considerations
Corten can stain contacting surfaces (e.g., light-coloured stone, wood). If installing on a terrace, plan for a zinc drip edge or geotextile. The full maturation of the patina takes 18 to 36 months.
