💡 Tip: Combine outside and inside corners with straight retaining wall modules to create a harmonious and uniform look in your garden.
Corten steel requires no maintenance.
Over time, the surface develops a natural, protective rust patina that makes the steel extremely resistant to wind and weather.
🧽 Wash with mild soapy water after installation to remove the oil film.
🌦️ The patina develops from light orange to warm rust tones during the first months.
💡 To speed up the patination process, lightly spray the surface with a mild saltwater solution.
An outside 45° corner adds flexibility and finesse to your retaining wall design.
It creates fluid, cohesive lines and elegant transitions, whether used for level changes, planting areas, or flower beds.
🌿 Combine with inside corners and straight sections for a complete system

Why is 5 mm steel used for the tallest models?

Can corten steel stain the surface beneath?
