Corten Steel Planter 40x40x60 cm - Without Bottom
This self-assembly Corten steel planter belongs in gardens with clean lines. The sleek double-folded edge finish gives the whole piece more substance. The Corten steel planter is also extremely useful as a partition in hospitality establishments. Please note! Bottom not included; this can be ordered separately. The Corten steel planter gives gardens a powerful and warm appearance. This is due to the orange-brown color of the material, which is formed by a natural layer of rust. Another name for Corten steel is weathering steel: weather conditions have a positive influence on this planter. Corten steel is a metal alloy consisting of iron, to which copper, phosphorus, silicon, nickel, and chromium have been added. When exposed to the outdoors, the material becomes covered with a protective layer of rust. This natural rust layer provides protection against further corrosion. This gives the planter a long lifespan. Popular dimensions of Corten steel planters: Corten steel planter 50x50x50 Corten steel planter 60x60x60 Corten steel planter 100x100x40 Corten steel Planter 40x40x60 cm Specifications: 5 years warranty. Corten steel planters are very strong, wear-resistant, weather-resistant, low-maintenance, and durable. Standard material thickness of the Corten steel is 1.5 to 2 mm. Supplied as a self-assembly product and can therefore also be placed around an already planted tree or plant. Includes bolts, nuts, and an assembly manual. Products are delivered unrusted. The rusting process of Corten steel takes approximately 4-5 months, depending on weather conditions. Rust can be fixed by applying Owatrol. This is a penetrating anti-rust agent that forms a protective layer against rust. Owatrol protects the planter and ensures that the Corten steel no longer stains. Important points to note: Products must be unpacked immediately upon receipt so that any moisture between the packaging and the product is not trapped. This can cause irregular rust stains. Ensure good drainage. Do not use hydro granules: these retain moisture. We advise against using Corten steel within a radius of 2 km from a coastline. During the rusting process, rust water may run off the product. Planting advice: Fill the planter with a layer of Ø35 mm sorting pebbles (approx. 10 cm). Lay a water-permeable weed control fabric over the pebbles. Cover the weed control fabric with soil suitable for your type of planting.
