"Hot-dip Alu-zinc anti-fingerprint in coils/sheets Galvalume is a steel sheet with a protective coating of a 55% aluminum-45% zinc alloy, which is applied through a hot-dip process and also contains a small amount of silicon. This coating provides superior corrosion resistance compared to traditional galvanized steel by combining aluminum's barrier protection with zinc's self-healing properties. Galvalume is ideal for Coberturas de metal, paredes e outras aplicações de construção, especialmente em ambientes agressivos, como zonas de furacões ou áreas costeiras.
