The composition of the aluminum-zinc alloy used in 55% Al-Zn coatings has been proven to outlast galvanized steel by two to four times, depending on the environment. Building panels fabricated from 55% Al-Zn alloy-coated steel sheet will provide many years of trouble-free service when properly designed, installed and maintained. AZ30 Aluzinc Raw Material of prepainted steel coil for Aluzinc coating is 55% Al-zinc content, Galvanized coil is pure zinc. Aluzinc coil can have better anti corrosive ability, based on research. 2.
The improved corrosion resistance of 55% Al-Zn Alloy Coated Steel Coils are derived from the unique combination of the barrier protection of Aluminum and the sacrificial protection of Zinc. The formation of an insoluble Aluminum oxide layer provides the barrier protection while Zinc provides a sacrificial protection at cut edges, scratches and areas of coating damage.

MESCO STEEL,The biggest coating steel supplier in northest China,was founded in 2007, in past 13 Years,MESCO STEEL already exported 55 Countries and more than 450 clients,there is no Hot-Dip Zn-5% Al Alloy-coated Steel Sheets JFE a 100% chromate-free process for its 55% Al-Zn-coated steel sheet JFE Galvalume, which is widely used in building material applications. Based on these trends, JFE Galvanizing & Coat-ing, jointly with JFE Steel, developed a chromate-free conversion-treated Zn-5% Al alloy-coated steel sheet
The aluzinc steel coil with the cold rolled steel of different strength and thickness as substrate, it is produced through applying Al-Zn coat on both faces by hot dip process. In this coating, Al accounts for about 55%, Si 1.5%, Zn 43.5%. It enjoys both the physical protective property of Zn.
