Why choose this corten steel planter?
The elongated shape creates a powerful and balanced look in your garden or on your patio. The natural rust color develops gradually, giving your outdoor space a warm, timeless look that suits both modern and classic garden styles.
Made for long-term outdoor use
High-quality corten steel class A
This planter is made of corten steel class A. This material is known for its exceptional strength and weather resistance. You can leave the planter outside all year round, without worrying about frost, rain, or UV rays. The natural rusting process forms a protective layer that inhibits further corrosion, something that is often lacking in thinner or inferior types.
Belgian production with a focus on quality
This model is produced in Belgium. This means short lines, controlled production, and attention to detail. No mass production where tolerances and welds vary from piece to piece, but consistent quality that you can see and feel. You'll especially notice that difference after a few years of use.
With or without a base: here's how to make the right choice
You choose a corten steel planter without a base when you place it directly on the ground. Roots can then grow freely, and excess water drains away naturally. This is ideal for borders and gardens where plants are given the space to develop naturally.
A version with base is the right choice for patios, paved areas, and roof terraces. Thanks to the integrated drainage holes, water drains away in a controlled manner, protecting the substrate. This prevents moisture problems that often only become apparent later with less well-designed constructions.
Models with legs: flexible and practical
Certain models are available with legs. These are especially practical because they are easier to move. Especially in commercial and public environments where planters are used temporarily, for example, as a natural partition or visual barrier.
Sophisticated construction for stability
The top edge is folded 50 mm for extra strength and a sleek finish. Reinforcing ribs on the inside ensure structural stability, even with heavy plantings or larger dimensions. This prevents warping and sagging, which is common with other corten steel planters.
Natural rusting process with minimal aftercare
The planter is delivered unrusted and will develop its characteristic rust color within 6 to 12 months. If you want to accelerate this process, you can use a rust accelerator. Once the desired color is achieved, a rust fixer is recommended to limit rust water and keep the surrounding area tidy. (See smart combinations for the rust accelerator and rust fixer)
Planting advice per version
Without base
Place the corten steel planter directly on the open ground. Add a layer of gravel approximately 10 cm thick and cover it with a moisture-permeable anti-root cloth, extending at least 10 cm up the edges. Fill the corten steel planter with a loose soil mixture. Excess water can drain freely; tamping is not necessary.
With base
Place a drainage layer of approximately 10 cm of pebbles on the base and cover it with an anti-root cloth that extends up the edges. Fill the rust planter with an airy substrate. The drainage holes ensure controlled drainage and prevent water retention.
Confidence with your purchase
You receive a 2-year warranty and a 90-day return policy. This means you are consciously choosing a corten steel planter that is not only aesthetically pleasing but also technically sound and designed for years of trouble-free use.
