Corten steel requires no maintenance.
The surface develops a natural, protective rust patina that ensures long durability and a warm, vibrant look.
🧽 Lightly wash with soapy water after installation to remove the oil film
🌦️ The patina develops from light orange to deep rust brown over the first months
💡 For faster patination, lightly spray with salt water
Rounded joints give the retaining wall a more fluid and harmonious appearance.
The soft transitions create visual calm and make it easy to work with organic shapes, terrain and level changes – without compromising strength and stability.
