Corten Steel Planters

The use of Corten steel planters isn’t just for residential areas but is equally popular in commercial real estate. Compared to the standard wooden planters that you come across in the market, the corten steel planters are long-lasting and pretty amazing in terms of design and finish.

You might think they are expensive on your initial purchase, but you need to realize that they are here to stay with you for a long time. So, it is a good investment for the future and pretty eco-friendly as well. The best part about a corten steel planter is the design. With durability, you get the promise of a long-term design.

However, we understand that being familiar with the concept of Corten steel planters can be a little complicated for beginners. If you are in the same boat, we have all the information lined up for you in this guide. 

What is Corten Steel?

Let us round up and start from the basics. Corten steel is a popular type of weathering steel that is constructed with a blend of different steel alloys. This results in a durable material that develops a layer of rust over time. Before you get alarmed, let us clarify.

The rust layer on top acts as a protective layer and adds a very vintage and rustic look to the planter. But, that’s not all; the layer also works as a protective layer that eliminates your need for painting.

What is Corten Steel

If you think that Corten Steel is a new trend, it isn’t. It has been around since the 1930s. However, the use of Corten steel started with its inclusion in railroad cars, which was later used in storage cans and is now a popular inclusion for building planters.

A first look at a Corten Steel item will make you question its credibility. After all, who wants a rusted item, right? Well, that’s the specialty of it. The corten steel items are exposed to prolonged periods of sun and wet climate conditions, which creates a rust layer on top, otherwise known as the Patina.

The layer of Patina prevents risks of damage and further impact on the material, keeping it secure in the long run. There are different varieties of the corten steel, redcor being one of them. Unlike most types of Corten steel, Redcor is cold-rolled, while Corten steel is hot-rolled. 

Are there Safety Corners with Corten Steel Planters?

As we mentioned, the concept of the Corten Steel planters is fairly new. Although the material has been around for quite some time, it is only recently that people have started creating planters out of it.

But, are they safe for growing your plants? Are there any safety concerns that you should look out for?

When you have such a high-grade level of rust growing on the exterior, it isn’t surprising that people are going to worry that the metal will leech into the food plants or the standard flowering plants that one is growing. You can put that stress to rest because that isn’t the case.

  • It does seep in a little iron from the planter but that’s about it. So technically, the planter is only fortifying your plants with some extra iron. Even high acidity levels can’t break down the rust layer that covers the side of the planter, so growing any type of plant shouldn’t be of any concern, especially in terms of health hazards.
  • Also, if you are worried about the ecological aspect, there’s no need to worry about that as well. Yes, the planters are rusted from the exterior but they aren’t rusted to an extent that will cause unnecessary pollution to the environment if that is something you are worried about.
  • The only big issue with keeping a Corten steel planter in your backyard or garden is the staining. Since it is already corroded from the exterior, there are chances that the same will stain the surface you are keeping it on. So, if you keep it on top of a concrete surface, chances are that the same will eventually end up damaging the surface exponentially.
  • If you are buying a raw Corten steel planter that hasn’t been corroded yet, we’d highly recommend that you speed up the rusting process by spraying a mixture of vinegar and water on the surface. Even using hydrogen peroxide can help in sorting out the hassle a lot. 

Besides these safety measures, another important factor to know about the corten steel planters is the fact that they need a protective coating of polyurethane on top of the planter. Since it already has a layer of oxidation on top, chances are that you won’t need an extra layer of paint to go on top of the planter, so that’s a further relief.

Also, painting the corten steel planter isn’t a necessity but if you don’t particularly enjoy the rustic brown appearance of the planter, it is always ideal for you to go ahead and get paint of your choice to cover the exterior.

Which is Better – Corten Steel Planter or Galvanized Steel Planter?

Before we pit both of them against each other, we need to realize or understand the fact that both the corten steel and galvanized steel planters are amazing. They perform amazingly, not to mention that they are one of a kind as well.

Which is Better – Corten Steel Planter or Galvanized Steel Planter

We’d recommend both of these over the plastic planters, especially due to the credibility and the durability of the product in the long run.

Now, which one is a better option between the two we have.

  • Appearance 

Starting with the Corten steel planter. This is no doubt a hit or miss among people, especially ones that don’t like the rusty look. However, if you are one of those people that genuinely enjoy the old and rustic look of a planter; you are going to enjoy this one in particular.

However, when it comes to the appearance of a galvanized steel planter, it is a lot more uniform and it offers scope for more customizations than you’d expect. Since galvanized steel planters are sprayed with protective aluzinc powder coating, they have an even and smooth appearance to them.

  • Durability

Surprisingly enough, we’d have to give this one to the galvanized steel planters. They last a lot longer than you’d anticipate. The corten steel planters are at more risk of cracking and breaking from the sites that get excess humidity or exposure to the salt spray.

Galvanized steel planter, on the other hand, is rust-resistant and doesn’t experience any kinds of damage, even after years of prolonged usage. So, all in all, we’d recommend this as a superior option in comparison.

  • Interaction

Another factor about these two planters that every landscaper should be aware of is the interaction. They will interact among themselves if you keep them side by side or close enough. That’s probably the last thing that you want to do.

Since galvanized steel planters have a zinc layer on top of them, there are chances that the corten steel planters will react with them and cause damage in the long run. That’s probably the last thing that you want to experience with these expensive planters.

To conclude, everyone has different requirements and expectations from the planters they buy. So, what you need to do is ensure that you get good-quality planters that best suit the area and the landscape that you have.

Salt spray, which is common around beaches, is another area where we wouldn’t recommend using a Corten steel planter. You will only end up wasting away at your investment.

If you live in areas where it floods easily, these planters aren’t your thing.
