Otherwise known as weathering steel, Corten steel is an excellent insulator. This means that the soil in your planters will warm up much faster than it would in other types of planters or garden beds – Such as those framed with wood – Thus allowing you to get planting earlier on in the Spring.

Corten Steel is a unique material that offers a variety of benefits for both residential and commercial applications. Its long-term durability makes it a perfect choice for planters and climates that need to withstand the elements.
Increased longevity
Corten Steel is designed to withstand the elements and atmospheric corrosion, and as a result, it has a much longer lifespan than traditional steel. This increased longevity means it requires less maintenance and can be left in its natural state for extended periods. It's one of the many reasons why we use Corten Steel in planter design. Once you buy one planter, you'll likely have it for life!
Attractive appearance
Another advantage of Corten Steel is its unique aesthetics. As it weathers, the patina develops on the surface of the planter, giving it a distinctive look that many architects and designers find appealing.
Superior corrosion resistance
As we know, Corten has exceptionally high resistance to corrosion because it is a copper chromium alloy steel. Compared to other unalloyed steels, this alloy exhibits superior resistance to atmospheric oxidation. Protective coatings form on the steel's surface and prevent further rusting when exposed to the elements and potentially harsh weather conditions.
Natural oxidization
When exposed to air, the natural oxidization process forms a protective oxide layer on iron, making it less likely to rust over time. This patina is also known for giving metal objects an antique charm as the warm brown hue changes in tone with the passing years and its external environment.
Enhanced durability
One of the most essential advantages of Corten Steel is its durability. Corten Steel is more durable than traditional steel (e.g., carbon steel). It is resistant to both abrasion and impact, meaning it will not easily dent, ding, or scratch. Corten is suitable for building solid structures, and Corten Steel in planter design is becoming an increasingly popular option among garden enthusiasts and landscape designers.
Reduced maintenance costs
Because Corten Steel is so durable, it requires less maintenance than traditional steel. This lower maintenance is a benefit of Corten Steel and can result in substantial cost savings over the life of a Corten Steel structure.
Sustainability
Corten Steel is also a more sustainable choice than traditional steel. Because it is so durable, Corten Steel can be reused or recycled at the end of its lifespan without losing any of its strength or durability.It can be recycled almost 100% by returning to the foundry after the project's lifespan.
Cost-effective
Yes, Corten Steel Planters are cost-effective. The initial investment might be higher than other materials, but the long-term savings on maintenance and replacement costs make them a wise choice. The durability and minimal maintenance required contribute to significant cost savings over time, making it another one of the benefits of Corten weathering steel.
Are Corten Steel Planters Safe
Gardeners may wonder about Corten steel planter boxes and whether or not they're safe for growing food and for the ecosystem. These concerns can be laid to rest! A Corten steel planter box doesn't leach any dangerous materials into the ground, only a little iron. When high acidity can't break down the protective coating prematurely, adding a little more iron into your planter box or raised bed promotes the development of chlorophyll in plants.
The same goes for the ecosystem around your Corten planters. There isn't enough corrosion happening to be worried about pollution. One thing to consider, however, is that Corten planter boxes can stain hardscapes. Gardeners should lay down a tarp, matting, or some other material that will prevent unwanted staining on concrete or decking. Combine it with gravel to highlight the hue of the nice planter boxes!
It takes a little time for your raised bed's natural, protective patina to develop. To speed up its development on Corten steel planter boxes, we recommend combining 2 oz of vinegar, ½ teaspoon of salt, and 16 ounces of hydrogen peroxide in a spray bottle. Shake the bottle vigorously to combine the ingredients. With gloves and goggles on, spray the entire surface of the planter box. Wipe it with a towel if the spray texture on the planter needs smoothing. This speeds the development of the patina, and a protective coating forms on the oxidized metal. Repeat the process over time, allowing it to dry between treatments until you achieve the desired look on your metal planter. Pretty easy!
Once the oxidized patina is fully developed to suit your preferences, you've got a great protective coating of oxidation that stabilizes your planters. You can even lock in the color with a coat of polyurethane paint after the patina is completely formed. Before painting the entire metal planter box, ensure the Corten steel planter box is the color you want it to be, and test a small area as the polyurethane coating may make it look darker in appearance. You don't have to coat the planter if you don't want to; it will still be a nice planter visually with or without that extra coating!

How to Use Corten Steel Planters in Your Garden Design
Commercial gardens
Bold entrances
As mentioned in the small gardens section, corten steel planters can make an impressive entrance to a building, so why not use this to give a welcome to the customers visiting your commercial premises? A pair of large planters, one either side of an entrance, could be quite a statement. It can either be filled with a changeable seasonal display, clipped topiary, or lower maintenance plants such as evergreen shrubs or grasses.
Public seating areas
Public spaces can often be uninspiring places that collect litter and municipal or commercial planters are often full of weeds. Instead, go for a set of good-sized corten steel planters, filled with low upkeep plants or seasonal bedding displays. The planters themselves are long-lasting so should be a good investment requiring minimal maintenance.
Branding
The sides of corten steel planters can easily be branded to help your business stand out. When planted with a gorgeous display it surely has to be better to look at than an ordinary billboard!
Rooftop gardens
Windbreaks
Corten planters can be positioned on rooftop gardens to provide protection from weather or prevailing winds. They are durable and long-lasting so should stand up well to the elements, not cracking in frosts like terracotta pots, rotting in wet weather like wood, or cracking in strong sunlight, like some plastics.
Aesthetic consistency
As mentioned before, the use of a distinctive material like corten steel can really help to knit a design together. You may have different areas to your rooftop space – maybe a sun terrace, outdoor kitchen, or eating area but by using corten steel throughout this can help to bring the whole rooftop garden together without compromising the individuality of each different space.
How to Use Corten Steel Planters in Your Garden Design




Placement
As explained above, the rust-like layer that forms on the surface of your Corten steel is absolutely essential to its longevity. Corten steel is designed to develop its protective oxide layer upon exposure to oxygen and humidity in the air. Therefore, any steel placed below the ground will corrode at a different rate to Corten steel placed above the surface. This means that the lifespan of our Corten planters and garden edging products will depend on placement.
Patina
The patina that Corten steel develops is also completely unique to local conditions, with soil and atmosphere also impacting the natural corrosive process. There have even been some instances in which Corten steel structures have had to be taken down because the local climate simply wasn't conducive to a protective layer developing, even after many years. Take the Omni Coliseum in Atlanta, for example, which failed to rust even after 25 years. Luckily, with the UK climate, this needn't be a concern, as the most favourable conditions consist of alternating wet and dry weather – something we're by no means short of!
Thickness
Most of our Corten steel planters are made from structural-grade Corten steel measuring 2 mm in thickness, meaning they should remain fit-for-purpose for an extremely long time. Indeed, many companies report that their 2 mm Corten steel can last for up to 25 years. Moreover, most material loss will actually occur in the first few years and is so negligible that you will barely notice it.
