BARREL Cortern Steel 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:

• 5-year guarantee.

• Corten steel planters are very robust, hard-wearing, weatherproof, low-maintenance and durable.

• The planter has feet and drainage holes. These allow the planter to float a little above the ground (90 mm) and provide optimal drainage.

• The corten steel has a standard thickness of 3 mm.

• 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.

Key points of interest:

• Products should be unpacked immediately upon receipt to release any moisture trapped inside the packaging. If the product is left in its packaging, it may develop uneven rust patches.

• Ensure proper drainage.

• Do not use an overflow pipe; no excess water should remain in the corten steel planter. This can cause the metal to corrode due to the interaction of oxygen and soil.

• Do not use hydro pellets: they retain moisture.

• We do not recommend using corten steel within 2 km of a coastline.

• The guarantee expires if you drill or grind in a way that is not specified.

• The weathering process may cause rust run-off.

PLANTING ADVICE:

• Cover the bottom of the planter with a layer of gravel (approx. 10 cm, Ø35 mm grading).

• Place a permeable anti-root membrane over the gravel.

• Cover the membrane with soil suitable for your chosen plants.

• Do not use an overflow pipe; no water should remain in the corten steel planter.
