Steel
Nola uses high-quality steel with good strength in our products. Steel rusts if left untreated and must therefore be surface treated.
Hot-dip galvanized or electrogalvanized and powder coating
Available in either only hot-dip galvanized steel or electro-galvanized and powder-coated steel.
Hot-dip galvanizing provides very strong protection against corrosion. The steel is dipped into a bath of hot liquid zinc. The zinc attaches and creates a surface coating on the steel part, which is then taken out of the bath and drained of excess zinc.
Electrogalvanizing provides corrosion protection through the sacrifice of zinc ions. It is created via a zinc coating on the steel using an electric current. 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.
