Cold Rolled DX51D Z100 zinc coated galvanized steel gi coil for roofing

What are advantages of galvanized steel?
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.
>>Machinability: It can satisfy the processing requirements of rolling, coiling and others processes alike.
>>Thermal resistance: Common HDG steel plate normally works under 230℃, and has its color changed at 250℃, however, Galvanized steel plate can sustain the environment at 315℃ for long time.
>>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.

Applications of Cold Rolled DX51D Z100 zinc coated galvanized steel gi coil for roofing:

construction, automobile,container,transpotation, and household appliances and other files.
