Aluzinc steel, a special type of cold-rolled galvanized steel, boasts a metal coating made up of 55% aluminum, 43% zinc, and 1.6% silicon. This unique composition provides superior long-term corrosion resistance, which is 2 to 6 times better than traditional galvanized coatings. Additionally, because aluminum is less dense than zinc, aluzinc steel sheets offer a coverage area that is 3% larger than that of galvanized steel sheets with the same weight and thickness.
