The gorgeous curves of the ONYX will add style to your garden. Its rounded shape gives it a soft look. Corten steel adds warmth 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.  

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 and makes the product long-lasting.

SPECIFICATIONS:

• 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.
