What are advantages of Zn coat galvanized steel coil?

Because it is produced through applying Zn coat on both faces by hot dip process. It enjoys both the physical protective feature and the electrochemical protective property of Zn.
High reflectivity: Reflection ability of heat and light is twice as much as those of hot-dip zinc steel sheet, and its reflectivity is more than 0.70, which is an ideal construction materials of saving energy.
