Steel retaining wall

modularfor green spacesfor public spaces

Product overview
Create structure and levels in gardens and public spaces with a folded corten steel retaining wall available in 3 or 5 mm thickness. The folded edges increase rigidity and give a precise, architectural finish. The warm rust patina of corten steel develops naturally over time, offering an aesthetic, maintenance-free solution in Danish design — suitable for private gardens, parks, and landscape architecture projects.

Assembly & delivery
All walls are made to order and shipped from byJEMA within 5–10 business days. Use the shorter sections (24.5 and 49.5 cm) for corners and terminations and longer lengths for continuous clean lines. Assembly instructions (PDF) are provided.

Maintenance
Corten steel is essentially maintenance-free: the surface forms a protective rust patina that prevents further corrosion. After installation, rinse with mild soapy water to remove the oil film. Colour progression ranges from bright orange to deep rust brown. To accelerate patination, lightly spray with saltwater.

Inspiration
A corten retaining wall is both functional and aesthetic — ideal for modern gardens, plazas and green infrastructure. Use it for terrain division, terraces and level differences. Combine corner and straight modules for harmonious compositions and pair with corten planters and raised beds.
