Product overview
Create structure and warmth in your outdoor space with the CUBY planter box in 2 mm corten steel. Precisely folded edges deliver clean joints and increased rigidity so that form and function combine in a restrained, architectural expression.

Maintenance
Corten steel requires no routine maintenance and is designed for year-round outdoor exposure. The characteristic rust layer forms a protective barrier that limits further corrosion. Rinse lightly with warm soapy water after installation to remove any oil film. When placing the planter on tiles or sensitive surfaces, use the optional bottom plate or a suitable base to avoid rust marks and ensure proper drainage.
