The TRIANGLE, as the name suggests, is a triangular planter. Thanks to its specific geometric triangle shape, it is very suitable for filling difficult spaces in the garden in various playful compositions. Or to very simply fill an internal corner.
- 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 staal 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.
- 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.
A new shape: characterised by the same angles as those of a geometric triangle. Our corten steel TRIANGLE has a warm appearance and can be beautifully combined with other corten steel elements in the garden. The TRIANGLE is for those looking for something just a little different!
The planter’s warm appearance comes from its distinctive orange-brown patina, which is the result of 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 so you can enjoy the TRIANGLE for many years.
SPECIFICATIONS:
- 5-year guarantee.
- Corten steel planters are very robust, hard-wearing, weatherproof, low-maintenance and durable.
- The planter has hidden feet (15 mm) and drainage holes, which allows it to float a little above the ground and provides optimal drainage.
- The corten steel has a standard thickness of 2 mm.
- The product can be customised. Please contact us for the possibilities.
- Products are delivered without rust. The corten steel weathering process takes about 4–5 months, depending on weather conditions. You can speed this up by using our rust accelerator.
- 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.
