The Quadra 40x40x40cm is a square planter made of Corten steel that fits into all types of gardens.

Corten steel is an extremely durable and timeless type of steel, and this planter is made of Class A Corten steel, which is a metal alloy consisting of iron.

Corten steel is strong, ecological, and fully recyclable.

The rusting process of Corten steel often takes more than 1 year, and the final color varies each time.

This depends on the specific atmosphere and conditions in which the product is located.

The product is delivered in a grey color, and from that moment, the product begins to discolor.

The final color can change from deep orange to dark brown.

The planter includes a drainage hole.

How long does the rusting process take?

Upon delivery, Geroba's products often do not yet have the beautiful typical orange-brown color.

The formation of the rust layer begins after 2 to 3 weeks and is only completed after approximately 1.5 years.

The alternation between wet and dry weather is important for the formation of the protective layer.

The exact duration depends heavily on the weather and the location where you place the product.
