Corten Steel Planter 300 x 100 x 80 cm
This planter with straight angles belongs in gardens with clean lines. The sleek double-folded edge finish gives the whole piece more substance. This corten steel planter is also extremely useful as a partition in hospitality establishments. Corten Steel Planter Features This corten steel planter gives gardens a powerful and warm appearance. This is due to the orange-brown color of the material, which forms through 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. As a result, the planter has a long lifespan. Corten Steel Planter Specifications: 5-year warranty. Corten steel planters are very strong, wear-resistant, weather-resistant, low-maintenance, and durable. Includes feet and drainage holes. This ensures that the planter floats slightly above the ground (15 mm) and has optimal drainage. Standard material thickness of the Corten steel is 2 mm. Other material thicknesses are also possible. Customization is possible. 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 proper drainage. Do not use an overflow pipe; no excess water should remain in the Corten steel planter. The material can then rust through due to a combination of oxygen and soil. 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. The warranty is void if you drill or grind in a manner that is not prescribed. PLANTING ADVICE: Provide the soil with a layer of Ø35 mm sorting pebbles (approx. 10 cm). Lay a water-permeable root barrier fabric over the pebbles. Cover the root barrier fabric with soil suitable for your type of planting. Do not use an overflow pipe; No water should be allowed to remain in the Corten steel planter.

What are good 300 cm Corten steel planters?
Good 300 cm Corten steel planters are characterized by their structural strength. For a length of 3 meters, a minimum steel thickness of 2 mm (often even 3 mm for extra stability) is essential to prevent the walls from shifting under the enormous pressure of the soil filling. High-quality models are equipped on the inside with strategically placed tie rods or reinforcing ribs that keep the side walls perfectly in line. Additionally, you can recognize a good large planter by the sleekly finished, double-folded top edges. This not only provides a luxurious appearance but also ensures the necessary rigidity along the entire three-meter length.
Why choose a 300 cm Corten steel planter?
Choosing a 300 cm Corten steel planter is ideal for those who want to bring structure and tranquility to their garden. With a length of 3 meters, this planter functions perfectly as a natural room divider on a large terrace or as a robust border along a driveway. Moreover, Corten steel is virtually indestructible; the characteristic rust layer protects the underlying metal from rusting through. This makes an XL planter a sustainable investment that will last for decades. The warm, orange-brown patina forms a stunning contrast with long rows of ornamental grasses or a sleek hedge, instantly giving your garden a professionally designed look.How do you install 300 cm Corten steel planters?
Due to the weight and length, installing 300 cm Corten steel planters requires proper preparation. A 100% flat and stable surface is necessary to prevent tension on the welds. Follow these steps for optimal results:
- Foundation: Place the planter on a sturdy patio or a strip foundation of concrete curbs to prevent subsidence.
- Spirit level: Use a long spirit level to check that the planter stands straight over the full 3 meters.
- Installation space: Take the turning radius into account upon delivery; A planter of this size is often delivered by large transport and cannot easily pass through a narrow gate.
How do you fill a 300 cm Corten steel planter?
Filling a 300 cm Corten steel planter requires significant amounts of material. Start with a layer of hydro granules of approximately 10 to 15 cm for good drainage. Place a high-quality root barrier fabric over this to prevent the potting soil from washing between the granules. Because a 3-meter planter catches a lot of sunlight, the steel can get hot. It is therefore advisable to line the inside with EPS insulation boards or bubble wrap. This protects the roots against temperature fluctuations and prevents the soil from drying out too quickly. Fill the rest with high-quality garden soil, specifically tailored to the plants you choose.
Maintaining a 300 cm Corten steel planter
Maintaining a large 300 cm Corten steel planter is surprisingly simple. The material is designed to stay outdoors and requires no paint or stain. The rust layer is self-healing; any scratches will disappear on their own through oxidation. However, it is advisable to rinse the planter occasionally with tap water to remove atmospheric pollution or leaf buildup, especially on the underside of the edges. Never use abrasive agents or a high-pressure cleaner, as this can damage the natural protective layer. This way, your 3-meter long planter will remain a radiant centerpiece in your garden design for years to come.

Frequently asked questions about the 300 cm Corten steel planter
How much soil fits in a 300 cm planter?
The capacity of a 300 cm Corten steel planter depends on the width and height. For a standard size of 300x50x50 cm, approximately 750 liters of filling is required. We advise always calculating the capacity generously, including the layer of hydro granules for healthy water management.
Can a 3-meter planter warp?
No, provided the planter is of good quality. Our Corten steel planters are equipped with internal reinforcements (strips or tie rods). These ensure that the walls of the planter are not pushed outwards by the weight of the wet soil, keeping the planter straight along the full 3 meters.
Is a 300 cm Corten steel planter delivered in one piece?
Yes, at Planten247 we opt for maximum quality, and every 300 cm planter is delivered as one fully welded object. The planter is therefore ready for immediate use and requires no assembly. Before purchasing, be sure to check carefully whether the route to the final spot in the garden is wide enough for this impressive 3-meter size.
Does a 3-meter Corten steel planter produce a lot of rust stains?
During the rusting process in the first few months, any Corten steel planter can release rust water. With a 300 cm planter, the surface area is large, meaning that a significant amount of water runs down the walls during rain. We recommend placing the planter on a surface that is easy to clean or where stains are not a nuisance.
