• 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.
• Because this planter has no base, there’s no need for an overflow pipe.
• Do not use hydro pellets: these 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:

• Fill the bottom of the planter with a layer of gravel (Ø35 mm grading, approx. 10 cm).
• Place a permeable anti-root membrane over the gravel.
• Cover the membrane with soil suitable for your chosen plants.

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 corten steel has a standard thickness of 2 mm. It can also be supplied in other thicknesses.
• Ideal for planting large plants or trees. The bottomless planter allows for maximum root growth.
• 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.
