1.Prepainted Steel Iron Sheet 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 and sophisticated.
2.Prepainted Steel Iron Sheet main usage:
1) Often used as building materials(ceiling, metal roof tile)machinery parts(electrically controlled
cabinets,road maintain board, etc,
2) Mainly used in advertising industry, construction, household appliances industry, electrical
industry, furniture industry and transportation.
3.Prepainted Steel Iron Sheet quality control:
Strict procurement process---skillful technical workers---final products inspection (resistance to corrosion,salt spray test,exposure test,machinability,thermal resistance)
---standard packing

5.Prepainted Steel Iron Sheet coating types and function:
1)Polyester(PE)
Good formability and adhesion, color is rich and various, superior durability in the outdoor,
good chemical resistance and low cost.
2)Silicon modified polyester(SMP)
Good wear resistance and heat resistance, as well as good exterior durability and resistance
to pulverization, medium cost.
3)High durability polyester(HDP)
Anti-ultraviolet and excellent color retention, excellent resistance to pulverization, good
adhesion, color is rich, good cost performance.
4)Polyvinylidene fluoride(PVDF)
Strong performance of anti-ultraviolet,can stand against strong change of weather for long
time and erosion for many kinds of chemical medium, excellent solvent resistance, ,dirty
resistance, color is limited and high cost.
