Corten Steel Retaining Walls: A Durable Landscaping Solution

Retaining walls are one of the most useful tools in landscaping, and they serve both practical and aesthetic purposes. With a retaining wall, you are able to segment your landscape into different areas while creating a raised bed that can be used for gardening. When it comes to retaining wall materials, Corten steel is one of the best options available on the market. In this post, we take a closer look at some of the advantages of Corten steel retaining walls to help you make a more well-informed decision when it comes to your landscape.

What is Corten Steel?

Corten steel is a type of steel alloy that contains copper, chromium and several other metals. This unique combination of materials gives the steel a unique characteristic in that it develops a protective rust-like layer on its outer surface over time when exposed to the elements. Unlike rust, this protective layer is not harmful to the steel and also does not reduce its longevity. Instead, it helps to keep the rest of the steel underneath protected from further corrosion from the elements and gives the steel a unique look.

Advantages of Corten Steel Retaining Walls

Because of its properties, Corten steel is a great material for outdoor applications, including retaining walls. Some of the advantages of Corten steel retaining walls include:


The protective outer layer that forms on Corten steel helps to enhance its durability by ensuring that the underlying steel is not subjected to corrosion. This means that Corten steel retaining walls are often able to last for a long time without needing repairs or replacement.

Aesthetic Appeal

The unique aesthetic of Corten steel can be appealing to certain homeowners who prefer a rustic and weathered design style. The natural patina added by Corten steel can also give it a unique texture, making the material truly one of a kind.

Low Maintenance

Corten steel is relatively low-maintenance and does not require frequent upkeep to ensure that it is in good working order. This is unlike some other materials, such as timber, which will require regular inspection to ensure that it has not been affected by insects or rot.


Like other types of steel alloys, Corten steel is also extremely strong and able to withstand significant pressure. This means that a Corten steel retaining wall will be less likely to warp under the weight or pressure exerted by the soil that it is holding back.
