The Domus corten steel planter will add boldness and warmth 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. The Domus planter has a distinctive 'floating' rim around the top. This will create a light and dynamic look in gardens and on patios. 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. 5-year guarantee. Corten steel planters are very robust, hard-wearing, weatherproof, low-maintenance and durable. The planter has hidden feet 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. Products are delivered without rust. The corten steel rusting process takes about 4-5 months, depending on weather conditions.
