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.
Stainless steel is an iron alloy with at least 10.5% chromium that often has good resistance to corrosion (rust) and other chemical attacks. A common misconception about stainless steel is that it does not rust at all; it can in fact corrode, especially in environments near the sea with high humidity.
Aluminum is a soft light metal that is silvery to gray in color. Depending on the alloy, aluminum usually has good corrosion resistance. It is common for the aluminum to be extruded into tubes or rolled into a plate in the desired material thickness.
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.
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.
