What is the difference between galvanized gi steel plate and aluminium-zinc gl plate?

1. Aluminized zinc plate is composed of 55 percent aluminum, 43.5 percent zinc and a small amount of other elements.Galvanized sheet is only the surface of the steel plate plated with a layer of zinc, the main component or iron.
2. As long as there is corrosion in one point, it will slowly spread to other places.And galvanized sheet appears a certain point of corrosion, it will not spread.

3. On the surface of the aluminized zinc plate, there are many honeycomb structures. The nests made of aluminum are covered with zinc, which acts as an anode protection.Galvanized sheet is just a smooth layer of zinc, for the steel plate to resist external damage, slow corrosion.
