Characteristics
The CARREZ corten steel planter will add warmth and boldness to any garden, 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.

Key points of interest:
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 weathering process may cause rust run-off.
PLANTING ADVICE:
Place a permeable anti-root membrane over the gravel.
Cover the membrane with soil suitable for your chosen plants.
