The main difference between galvanizing and Galvalume is that galvalume is a combination of zinc, aluminum, and silicon, while galvanizing is 100% zinc. The makeup of the three elements in a Galvalume coating is just over 50% aluminum, just under 50% zinc, with trace amounts of silicon.
An advantage that Galvalume has over normal galvanized material is that it has enhanced protection abilities. Over time, Galvalume tends to perform better than galvanized steel, especially when exposed to water or other liquids that ca...
