Aluzinc steel, also known as galvalume or zincalume steel, is a premium cold rolled galvanized steel featuring a unique metal coating composed of 55% aluminum, 43% zinc, and 1.6% silicon. This composition offers a powerful combination of aluminum's physical protection and durability, along with zinc's electrochemical protection. As a result, aluzinc steel coils provide superior performance in various demanding applications.
