1. Color Coated Galvanized Coil brief introduction
It is extensively used in many industries. Different grades and surfaces can be used in diversified
environments. Common applications of prepainted galvanized steel sheet in coils are as following
1) Architecture, construction, and building structures
2) Kitchenware, hardware, cutlery and tableware
3) Chemical, petroleum and machinery industries
4) Automotive and aerospace structures
2. Color Coated Galvanized Coil tipical features
Strict procurement process---skillful technical workers---final products inspection (resistance to
corrosion, salt spray test, exposure test, machinability, thermal resistance)---standard packing

4. Color Coated Galvanized Coil advantages
1) Excellent corrosion resistance: The zinc layer provides a good protection.
2) High heat resistance: Reflective surface of material aids in efficiently reflecting the sunlight away
3) Aesthetics: Available in plethora of patterns and multiple sizes as per the requirements
4) Versatility: Can be used in the various areas
