Comparing Aluminum-Zinc Alloy to Galvanized Metal – KPS Global Nov 15, 2019 · An aluminum-zinc alloy metal is less prone to rusting than normal galvanized steel, and less likely to completely break down, even after a few decades. An aluminum-zinc alloy offers many advantages when compared to galvanized metal. Aluminum-zinc acts as a sturdy, defensive barrier that resists rust, the elements and fire. Galfan zinc-aluminium alloy coating (ZA) – SSAB Galfan (ZA) is a zinc-aluminiu...
