The ONYX is a welcome addition to our collection. This planter has a beautifully balanced organic form, giving it an absolutely unique appearance.
The gorgeous curves of the ONYX will add style to your garden. Its rounded shape gives it a soft look. Corten steel adds warmth 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 and makes the product long-lasting.
SPECIFICATIONS:
- 5-year guarantee.
- Corten steel planters are very robust, hard-wearing, weatherproof, low-maintenance and durable.
- The corten steel has a standard thickness of 2 mm.
- 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 corten steel to rust through 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 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.
Warning! Do not use an overflow pipe: no water should remain in the corten steel planter.
