The CIRCUM planter is characterised by its round shape. It's available in corten steel, aluminium and fibreglass. This cylindrical planter brings gardens to life even more!
The CIRCUM corten steel planter gives gardens a bold, stylish and warm look, thanks to the orange-brown patina on the metal. This patina is formed by a natural layer of rust. Another name for corten steel is weathering steel: weather conditions have a positive effect on this planter.
Corten steel is a metal alloy made by adding copper, phosphorus, silicon, nickel and chromium to iron. When exposed to air, the material forms a protective layer of rust. This natural coating prevents further corrosion, extending the planter's life.
SPECIFICATIONS:
- 5-year guarantee.
- Corten steel planters are very robust, hard-wearing, weatherproof, low-maintenance and durable.
- The planter has feet and drainage holes. These allow the planter to float a little above the ground (90 mm) and provide optimal drainage.
- Because this planter has feet, it's easy to move, for example, with a pallet truck or forklift.
- The corten steel has a standard thickness of 2 mm. It can also be supplied in other thicknesses.
- The planter can be customised.
- Products are delivered without rust. The corten steel rusting process takes about 4-5 months, depending on weather conditions.
- The rust can be fixed by applying Owatrol. This is a penetrating rust inhibitor that forms a protective anti-rust coating. Owatrol protects the planter and stops the rust on corten steel flaking off.
- Products should be unpacked immediately upon receipt to release any moisture trapped inside the packaging. If the product is left in its packaging, it may develop uneven rust patches.
- Ensure proper drainage.
- Do not use an overflow pipe; no excess water should remain in the corten steel planter. This can cause the metal to corrode due to the interaction of oxygen and soil.
- Do not use hydro pellets: they retain moisture.
- We do not recommend using corten steel within 2 km of a coastline.
- The guarantee expires if you drill or grind in a way that is not specified.
- The weathering process may cause rust run-off.
PLANTING ADVICE:
- Cover the bottom of the planter with a layer of gravel (approx. 10 cm, Ø35 mm grading).
- Place a permeable anti-root membrane over the gravel.
- Cover the membrane with soil suitable for your chosen plants.
- Do not use an overflow pipe; no water should remain in the corten steel planter.
