What Is Corten Steel?

The Corten steel brand (also known as Cor-Ten steel for the trademarked brand) was created with the intention of creating a weathered, rust-like appearance over time with exposure to the elements. This type of steel is also known as weathering steel and does not require you to paint or treat your raised beds with anything. It is expected that the material will develop a rusted patina on the surface, but it will never rust through.

In choosing materials for raised beds that will be used in a kitchen garden, we try to prioritize those that are natural, beautiful, durable, sustainable, as well as affordable for use in an edible garden. Despite the fact that corten steel isn’t the most affordable option on the market, you can’t find a much more durable option than steel, which can quite literally last a lifetime if properly looked after.

There has been a rapid increase in the popularity of corten steel, and many of our Rooted Garden customers choose corten steel for the beauty of the weathered appearance it offers. (In case you prefer a more sleek, modern look, you might want to consider powder coated metal, which has a smooth finish and is equally as durable.)

While the corten bed itself can be a bit expensive, you’ll save a lot of money in the long run by not having to replace rotted materials and ensure you’re able to make the most of your gardening space for a long period of time.

Let’s take a look at the benefits of using steel in your kitchen garden and why you should consider it.
