THE PROCESS OF PE PRE-PAINTED ALUMINUM COIL :
the process of the coated aluminum coil

Classification of coated aluminum coil:
As per types of surface coating of paint, color coated aluminum coils can be divided into polyester (PE) coated aluminium coil,
 fluorocarbon (PVDF) coating aluminium coil and Epoxy coated aluminum coil
According to the thickness of the coating, it can be divided into single-coated aluminum coil (4-20 microns); 
double-coated aluminum coil (25 to 28 micron) and triply-coated aluminum coil (35-38 micron).
