How it works
Corten steel contains elements (copper, chromium, nickel) that make the surface rust dense and well bonded. The layer forms over a few months of alternating rain and drying, and then protects the metal underneath.
Where it works well
- Planters and garden edging.
- Decorative panels and fences.
- Façades and architectural features.
What to watch out for
- In the first months, water running off corten steel can stain the paving or stone underneath.
- It is not suitable for places that are always wet, or where de-icing salt builds up.
- The colour changes in the first year, from orange to dark brown.
The alternative: a rust-look finish
If you want the look without the stains of the first few months, there are finishes that imitate rust on protected steel. We will explain the differences and help you choose.
