Corten steel planters are very robust, resilient, weather-resistant, easy to maintain, and durable. They feature support feet (15 mm) or feet (90 mm) and drainage holes, ensuring the planters are slightly elevated from the ground and have optimal drainage. The standard material thickness of Corten steel is 2 mm. The products arrive without a rust layer. The rusting process to Corten steel takes about 4-5 months, depending on weather conditions. (During the rusting process, rust water may leach from the product.) Rust can be eliminated by applying Owatrol. This is a penetrating rust inhibitor that forms a protective layer against rust. Owatrol protects the planter and prevents the Corten steel from staining.
Important notes:
Products should be unpacked immediately upon receipt to prevent moisture accumulation between the packaging and the product, which can lead to uneven rust spots.
Ensure good drainage. Do not use an overflow pipe; no excess water should remain in the planter. The combination of oxygen and soil can then cause the material to rust through. Do not use hydro pellets. They retain moisture.
We advise against using Corten steel within 2 km of the coast.
Corten Steel Material Science: Corten steel is a metal alloy consisting of iron with added copper, phosphorus, silicon, nickel, and chromium. When the material is exposed outdoors, it develops a protective rust layer over time. This natural layer provides protection against further corrosion, giving the planters a long lifespan.
