💡 Tip: Combine the corners with straight retaining wall sections to create stable and uniform constructions with a professional finish.
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 over the first few months.
💡 To speed up the patination process, lightly spray the surface with a mild saltwater solution.
An inside 90° corner makes it easy to design precise and stable corner solutions in your retaining walls.
Create structure and cohesion in your garden with a consistent and architectural expression.
🌿 Ideal for edging, beds, and raised planters
