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:

- 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.
