These Corten Steel Inside Curve retaining walls are the perfect solution for separating lawns, borders and paths. The options are endless including using the walls to create raised beds.
The Corten Steel Inside Curve retaining walls will create a strong structural impact in the garden or other outdoor spaces.
The pre-fabricated, modular system makes it easy to invisibly join retaining wall elements together. Inspiration, ideas and easy ordering for your retaining walls can be found on our Retaining Walls page.
The walls are available in 2 materials:
Corten and Aluminium.
The walls are available in the following shapes and each in 4 heights:
Straight Edge . Inside Curve (looking from the finished side, the ends of the piece curve towards you). Outside Curve (looking from the finished side, the ends of the piece curve away from you). Inside Corner (looking from the finished side corner the ends of the piece are nearest to you). Outside Corner (looking from the finished side corner the end of the piece are further away from you).
Please Note: If you are creating anything other than a straight wall then curves and/or corner pieces will be required. You cannot join two straight edges other than in line.
If you wish to create a less angular shape such as circle, oval or S shape then use curved edges, either on their own or in conjunction with the straight walls.
If you require other bespoke sizes please contact us by email or on 0345 6052505.
Details on how to design and build your retaining raised beds can be found here.
Corten steel is a metal alloy made by adding copper, phosphorus, silicon, nickel and chromium to iron. When exposed to air, the material forms a protective layer of rust. This natural coating prevents further corrosion, extending the life of the retaining wall.
The orange-brown patina of the metal contributes to the bold, warm look of this retaining wall. The colour is the result of a natural layer of rust. Another name for corten steel is weathering steel, with weather conditions having a positive effect on this material.

Includes stainless-steel fasteners. Products are delivered unrusted. The corten steel rusting process takes about 4-5 months, depending on weather conditions. Products should be unpacked immediately upon receipt to release any moisture trapped inside the packaging. If the product is left in its packaging, it may develop uneven rust patches. Corten steel should not be used in conditions that are continuously wet or damp. We do not recommend using corten steel within 2 km of a coastline. The weathering process may cause rust run-off. 5-year guarantee. The guarantee is invalid if you drill or grind the product in a way that is not specified.
The rust can be fixed by applying a Corten Varnish such as Owatrol. This is a penetrating rust inhibitor that forms a protective anti-rust coating. The Corten varnish can be applied to corten steel products to stop the weathering process and prevents rust on corten steel flaking off.
