About coated aluminum coil &pre-painted aluminum coil
Coated aluminum coil refers to the aluminum coil through coating and coloring treatment generally includes PE coated
aluminum coil and PVDF coated aluminum coil.Coated aluminum coil is widely used to manufacture aluminum composite
panel,aluminum ceiling,roofing,aluminum veneer,signboards.

Note of PE pre-painted aluminum coil:
1)Color difference maybe occurred in different production batch, so it is suggested all panels are placed
in one order for same project. And keep same direction as arrow on protective film when installing to
avoid any color difference by vision.
2)For custom' color requests, we can deal as following:
A. Supply a physical sample of custom color. A color sample on metal is preferred. If other, it is also acceptable.
But the color matching rate may be not good as color on metal.
B.New color sample is usually offered by our paint supplier in 5-7days,special color should be in 7-10 days.
C. Upon receipt of color sample, please approve in writing as soon as possible. Once you approved,
we will arrange purchasing and production.
3).For general colors, please refer to our color chart

THE PROCESS OF PE PRE-PAINTED 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).
