Advantages of Galvalume steel sheet (aluminized zinc steel sheet)

Galvalume steel sheet is a cold-rolled steel sheet as a base material and a galvalume steel sheet obtained by hot-dip aluminum-zinc alloy coating on both sides.

The alloy composition of the coating is 55% Al, 43.5% Zn and 1.5% Si by mass.

The physical isolation, electrochemical protection and trivalent aluminum ion doping of the aluminum-zinc coating make the aluminum-zinc steel plate have good corrosion resistance.

Under the same environment, the service life of galvanized steel sheet is 2-6 times that of ordinary galvanized steel sheet.

The corrosion resistance of galvanized zinc is 3-6 times that of hot-dip galvanizing

The good heat resistance of galvanized zinc can be used for a long time at high temperature.

The heat reflectivity is good, the reflection coefficient is twice that of the hot-dip galvanized sheet, which can reduce the indoor temperature and energy consumption
