Adding boldness and warmth to any garden space, the Corten Steel Onyx planters are elegant statement planters, whilst reminiscent of an ancient form. Enhancing the ambience of modern outdoor spaces, the steel oxidises naturally developing a beautiful shade of orange brown.

Constructed from 3mm Corten steel and available in a range of sizes, the Adezz Corten Steel Onyx planters are suitable in domestic gardens, commercial properties and public spaces - ideal for long and short shrubs and trees. Delivered un-rusted, the oxidised patina develops naturally when placed outside.
