This article reviews four of the best corten steel raised beds in the market today. It also provides you with a guide for choosing one that best suits your needs.

Before that, let’s look into why corten steel makes a better garden bed than wooden material.

Why Corten Steel Garden Beds Are Better Than Wooden Beds

One of the reasons corten steel garden beds are a better option is that they are resistant to weathering.

Their rusting does not eat away at the metal and instead insulates the plants and protects them against harsh external conditions.

On the other hand, wooden garden beds wear down after a while and have to be replaced often. To resist degradation, wood is usually treated with chemicals that end up getting soaked in the soil where food is growing, something that you would not have to do with corten steel.

The only type of wood that is known to last a long time is cedar. However, it is super expensive, and eventually, you would have to replace it as it is not entirely immune to degradation.

In the long run, getting a corten steel garden bed is way cheaper.

Moreover, you do not have to coat or paint corten steel. After a while, a beautiful stable rusty look forms and resists corrosion.

Therefore, you would not have to worry about it getting ruined by harsh conditions like humidity, rain, snow, or frost. On the other hand, you would have to apply a coating on wood so that it lasts longer.
