Because the density of 55% Al-Zn is lower than that of Zn, the area of aluminized zinc sheet is more than 3% larger than that of galvanized steel sheet under the condition of the same weight and the same thickness of gold plating.
Corrosion resistant
Zinc has active chemical properties. In the air at room temperature, a thin and dense alkaline zinc carbonate film is formed on the surface, which can prevent further oxidation, while aluminum can form an insoluble oxide layer in the air, which plays a protective barrier function.
Heat resistant
Aluminized zinc sheet can be used in high temperature environment up to 315 degrees.
Reflective
Aluminized zinc sheet has high reflectivity, its thermal reflectivity is almost 2 times of galvanized steel, very suitable for steel structure metal roof, can achieve energy saving effect.
Easy to paint on
The aluminized zinc sheet has excellent adhesion to the paint and can be painted without pretreatment and weathering.
