💡 Tip: Combine the corners with straight retaining wall sections to create strong, aesthetic constructions with a uniform finish.
Corten steel requires no maintenance.
Over time, the surface develops a natural, protective rust patina, ensuring long service life and a warm, lively appearance.
🧽 Lightly wash with mild soapy water after installation to remove the oil film.
🌦️ The patina develops from light orange to deep rust-brown over the first months.
💡 To speed up patination, lightly spray with a mild saltwater solution.
An inside 45° corner makes it easy to create cohesion and precision in your retaining wall designs.
It ensures stability and a refined result – whether you are working with level changes, terraces, or planting zones.

Why is 5 mm steel used for the tallest models?
