Aluzinc®

Aluzinc® sheet is a high-performance coated flat steel product manufactured by continuously hot-dip coating the steel surface with an aluminum-zinc-silicon alloy (AZ coating; approximately 55% aluminum, 43.4% zinc, and 1.6% silicon). The aluminum content provides excellent barrier protection as well as high heat and light reflectivity, while the zinc content provides cathodic protection to the steel, helping prevent corrosion at cut edges and scratched areas.
Compared with conventional galvanized steel sheets, Aluzinc® sheets offer significantly higher atmospheric corrosion resistance and a longer service life. They are widely and reliably used in roofing, façade cladding, sandwich panels, HVAC systems, household appliances, and general engineering applications. In addition to their distinctive metallic spangle finish, their recyclable and environmentally friendly structure makes them an economical solution for sustainable projects.
