PE Or PVDF 0.1mm - 2.5mm Pre Painted Aluminium Used For Household Appliances
Description:
Color coated aluminum (prepainted aluminum),which is produced with aluminum sheet or coil and processed by coating with color or pattern.
In common sense, here are two kinds of coating PVDF and PE.Compared with other section steel prepainted aluminum coil is the more popular material, because of its excellent property. Firstly the property is very stable so the surface is erosion resistant, warranty could up to 30 years long after special treatment. Then,the density is the lowest among metal material when volume is fixed.

Appliance of prepainted aluminium coil :
As per types of surface coating of paint, color coated aluminum coils can be divided into polyester (PE) coated aluminum coil, fluorocarbon (PVDF) coating aluminum coil and Epoxy coated aluminum coil.
Color coated aluminum coil is widely used in the roofing and cladding system, ceiling system, curtain wall plate, shutter, gutter, composite panel, can, home appliances board and embossed aluminum coil.
