ALZU® is a premium 55% Aluminium-Zinc alloy coated and colour coated steel product, available with high quality coatings. ALZU® steel is designed and manufactured by JFE MERANTI® to be an exceptional fit for roofing, walling and accessory applications within industrial, commercial, institutional and residential projects. ALZU® steel uses its alloy coating of Aluminium and Zinc to achieve excellent corrosion resistance performance and surface appearance. The ALZU® steel coating forms an interlaced mesh structure of Aluminium and Zinc. The Zinc-rich areas are the first line of defence in protecting the steel substrate, while the Aluminium-rich layer provides the second line of defence. These two layers work together to provide superior corrosion resistance performance for roofing and walling products. Show Less
