1. Prepainted Zincalume Steel Coil simple introduction
Printing or baking paints onto the surface of these materials above, pre-coated metal features
a wide range of colors and patterns, also has good corrosion resistance, which are commonly
used to make the exterior of buildings look more polished ans sophisticated
2. Prepainted Zincalume Steel Coil main usage
Often used as building materials(ceiling, metal roof tile) machinery parts(electrically controlled
cabinets,road maintain board, etc
3. Prepainted Zincalume Steel Coil quality control
Strict procurement process---skillful technical workers---final products inspection (resistance to corrosion,salt spray test,exposure test,machinability,thermal resistance)---standard

5. Prepainted Zincalume Steel Coil coating types and function
1) Polyester(PE)
Good formability and adhesion, color is rich and various, superior durability in the outdoor
2)Silicon modified polyester(SMP)
Good heat resistance, as well as good exterior durability and resistance to pulverization
3)High durability polyester(HDP)
Anti-ultraviolet and excellent color retention,excellent resistance to pulverization,good adhesion
4)Polyvinylidene fluoride(PVDF)
Strong performance of anti-ultraviolet, standing against strong change of weather for long time
