Corten Steel
Corten Steel Architectural Solutions
Weathering steel facades, screens, planters and custom metalwork designed to develop a rich, natural rust finish over time.
Built to Weather, Designed to Stand Out
Corten — weathering steel — forms a stable, protective oxide layer on its surface that deepens and enriches over time. The result is exceptional durability outdoors, low maintenance, and a distinctive architectural character that pairs beautifully with glass, stone, and landscape.
Why Choose Corten Steel?
- Natural evolving finish
- Strong architectural character
- Suitable for outdoor applications
- Low-maintenance surface
- Custom fabrication options
- Works with modern and industrial designs

Planning for Corten Steel
- Run-off during early weathering may cause temporary staining on adjacent surfaces — plan drainage and detailing accordingly.
- Proper drainage, drip edges and separation from porous materials are essential.
- Indoor or fully sheltered applications may require controlled treatment or protective coating.
- Natural variation in patina tone and texture is characteristic of weathering steel.
- Coastal or high-pollution environments may need additional assessment and maintenance planning.
Frequently Asked Questions
What is Corten steel?
Corten is a group of weathering steel alloys that form a stable rust-like appearance after exposure to weather. The surface oxide layer protects the steel beneath, reducing maintenance compared to conventional painted steel.
How does Corten continue to rust?
Exposure to moisture and air triggers oxidation. Over weeks and months the surface develops a protective patina that slows further corrosion while deepening in colour.
Can Corten be used indoors?
Yes, with proper specification. Sheltered or indoor installations often benefit from controlled pre-weathering or a clear protective coating to manage dusting and run-off.
How long does the rust finish take to develop?
Initial oxidation can appear within days to weeks. A mature, stable patina typically develops over several months depending on climate, orientation and exposure.
Will it stain flooring or walls?
During early weathering, runoff can stain porous surfaces. We recommend appropriate detailing, drip trays, drainage gaps and — where needed — temporary protection during the stabilisation period.
Can custom patterns be created?
Absolutely. We CNC laser-cut custom patterns for screens, panels and signage from your drawings or our in-house design team.
Is maintenance required?
Once the patina has stabilised, maintenance is minimal. Periodic rinsing may be advised in coastal areas. Indoor pieces may need occasional inspection if coated.
