Because of its many excellent characteristics,Prepainted Aluzinc Coated Roofing Sheet has been used in construction, light industrial, furnitrue, household appliances and so on.
1.Corrosion resistance.
The corrosion resistance of aluminized steel coils is mainly due to the protective function of aluminum and galvanized. When zinc is subjected to wear, aluminum forms a dense layer of alumina that prevents further corrosion of the corrosion resistant material.
2.Heat resistance
Al-Zn alloy steel sheet has good heat resistance, can withstand more than 300 degrees Celsius high temperature, and aluminized steel plate resistance to high temperature oxidation is very similar, often applied to A chimney, oven, illuminator, and fluorescent lampshade.
3.Thermal reflectivity
The aluzinc steel sheet has a high thermal reflectivity and is two times as much as galvanized steel. It is often used as a heat insulating material.
4.economical efficiency
Because the density of 55%AL-Zn is smaller than that of Zn, the area of galvanized steel sheet is 3% larger than that of plate under the same weight and the same thickness as the gold plating layer.
