The planters are made from rust-resistant sheet steel powder-coated.
The biggest planter 750 l is blasted, galvanized and painted.
Nola uses high-quality steel with good strength in our products. Steel rusts if left untreated and must therefore be surface treated. This is done through electro-galvanization and powder coating, hot-dip galvanizing, or application of a zinc powder primer.
Powder coating is a coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint, powder coating is usually applied electrostatically and then cured under heat or with ultraviolet light. The result is an even, hard-wearing coloured surface with the desired gloss level.
Electrogalvanizing (also known as zinc plating) provides corrosion protection through the sacrifice of zinc ions. It is created via a zinc coating on the steel using an electric current.
