Product Description
1. Product Introduction
Color coated aluminum coil is aluminum coil after cleaning, coating, and baking. Surface of aluminum coil can be painted to any color. YOGIC color-coated aluminum coil and aluminum sheet coils mainly come from Southwest Aluminum, Nanping, Chinalco, Ruimin, etc. which are the best raw materials suppliers domestically. Our coating paints are mainly from American PPG and Swedish Becker.

2. Application field
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.
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).
DongChuan 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.
