Our Corten Planters Range

Corten steel planters are a modern solution to traditional gardening containers. Unlike other materials that may crack, fade or degrade with exposure to the elements, Corten develops a protective rust patina over time. This layer not only shields the steel beneath from further corrosion but gives each planter a rich, textured finish that enhances with age.

At Buy Metal Online, our Corten steel planters include a wide selection of shapes and sizes to suit every type of space and planting scheme, including bottomless planters and planters with wheels or feet. Our collection of Corten steel planters includes:

• • Troughs
• • Cylinders
• • Bowls
• • Cubes
• • Round pots
• • Barrier planters
• • Tall planters
• • Tree planters

Whether you’re looking to add clean modern lines, define borders or enhance your garden aesthetic, there’s a Corten option to suit. Unlike wood or plastic, which can rot or become brittle, Corten steel is strong, reliable, and truly unique.

At Buy Metal Online, our Corten planters are available in a range of shapes and sizes, and we can also help with bespoke enquiries. Our planters are available individually or in sets, so whether you’re adding a single statement piece or planning a large garden layout, we’ve got you covered.

Popular Uses for Corten Planters

Corten planters are a great way to add long-lasting structure and visual interest to any outdoor space. As an alternative to timber, plastic, or concrete containers, they provide a hardwearing, frost-proof and architectural solution for planting and landscaping.

With a wide selection of shapes and sizes, you can create striking visual contrast or seamless integration with your garden layout.

Corten Steel Planters FAQs

Why choose our Corten steel planters?

Our Corten steel planters are built for durability, style, and performance. With a wide selection of options and a reliable UK-based team, Buy Metal Online makes it easy to elevate your garden design.

Are Corten steel planters good?

Yes, Corten steel planters are a great alternative to timber, plastic, or concrete containers. They are robust, weather-resistant, and add a unique visual element to your garden. Over time, Corten steel planters develop a protective patina that enhances their appearance and lifespan.

How long will a Corten steel planter last?

Corten steel planters typically last over 25 years, even in harsh climates. The natural protective layer on the outer surface prevents corrosion to the steel beneath, enhancing their appearance and lifespan. This makes them a highly durable option for outdoor planting!

Are Corten planters safe for vegetables?

Yes. Corten steel planters are a safe and popular choice for growing vegetables, herbs, and edible plants. Once the protective patina has formed, they provide a chemical-free planting environment without the need for paints or sealants. Unlike treated timber, for example, Corten steel does not leach harmful substances into the soil, making it an ideal option for food-safe gardening in raised beds and kitchen gardens.

Do Corten steel planters need to be sealed?

No sealing is needed. The weathering process naturally creates a protective barrier, eliminating the need for extra coatings.

Do Corten planters stain?

During the initial weathering stage, rust runoff from the planters may stain nearby surfaces like concrete or paving. This staining is temporary and will stop once the patina fully forms. To minimise this, avoid placing the planters on light-coloured surfaces or use protective mats underneath. Any affected areas can easily be cleaned with a chemical rust remover during the weathering process.

What is the most durable outdoor planter?

While durability varies by material, Corten steel planters are considered among the most hard-wearing. They resist rust, frost, and damage from the elements, making them a highly durable choice for all weather conditions and climates.

What are the best planters to leave outside?

Corten steel planters are an excellent choice for year-round outdoor use. They require no sealing, withstand harsh weather, and even look better with age!
