Color coated aluminum coils for roofing sheets are of alloys 1050, 1060, 1100, 3003, 3004 and 3105. 
Although there are 6 candidate alloys, only 3003 and 3004 are the most popular. 
1050, 1060 and 1100 are weaker in either hardness or corrosion resistance.

They are suitable for roofing sheets expected to last only years, especially when they are coated with PE paint.
 

The color coated aluminum roofing sheet coil is featured by low weight, good corrosion resistance and outstanding processing ability. In comparison to stone and pottery roofing sheets, aluminium sheets are much lighter, which indicates convenient installation and maintenance. Good corrosion resistance is an exclusive advantage of aluminium coil over other roofing materials. What’s more, the color coated aluminium coils for roofing sheets have durable and weather resistant coating of resin paints. This extends their service life substantially. Last but not least, the coated aluminum rolls will have to be bent and perforated before being made into roofing sheets, and the sheets need to be drilled for installation. 1000 and 3000 series of aluminium coils have proper elongation and hardness, just perfect for such processing methods. That’s why aluminium roofing sheets become increasingly popular.

Applications of Color Coated Aluminum Coil:

For its lightweight, beautiful appearance, as well as good anti-correction, color coated aluminum Sheet and Coil are vastly used in Exterior and Interior applications. Color coated aluminum coil are widely used in ACP,curtain panel,honey comb panel,shutter,roofing and most of the decoration areas.

Building	Venetian blinds, rolling shutters, ceiling panels, roofing, façade, ACP Panel. Eveas etc.
Roller Shutter	Aluminium Composite Panel (ACP), Ceiling, Roofing etc
Industry	an ideal material for white appliances such as refrigerator due to it's property of electrical and thermal conductivity, and corrosion resistance
Transport	truck body, caravan, buses, insulated and refrigerated vehicle
Signs	Application in Signs requires high colour consistency and flat surface. UAL can fulfill the requirements with excellent performance.
