What is Galvalume? GALVALUME sheet steel coating is an alloy of 55% aluminum, 1.6% silicon, and the balance of zinc by weight, this coating is approximately 80% aluminum.
Galvanneal steel includes the process of galvanizing with an added step â after the zinc coating, the steel is heated to around 1050Â° Fahrenheit. This process of extreme heating draws more of the iron out of the steel and causes it to mix with the zinc. The finished product has an alloy coating of approximately 90% zinc and 10% iron. In the realm of steel doors and frames there are three types of galvanized and galvanneal steel used â A40, A60, and G90. The differences in the three are based on the percentage of galvanneal coating per square foot and the protection they offer.
