Colour coated aluminum coils, as the name suggests, are painted on the surface of aluminum substrates. Commonly seen are fluorocarbon coated aluminum coil and polyester coil coated aluminium. They are usually used to manufacture building materials such as roofs, cladding and exterior walls. Widely used in aluminum-plastic panels, industrial factory roofs and walls, aluminum louvers, composite panels, aluminum ceilings, cans, and electronic products. Coated to protect against corrosion, UV rays and other environmental factors while also enhancing the material's aesthetics. Aluminum trim coils are available in a variety of colors and finishes, making them a versatile and popular choice for construction and decorative purposes.

Key Notes: Data range: The data in the table are typical values. The actual performance is affected by material thickness, production process (such as cold rolling rate) and test standards, and the specific warranty shall prevail.

State code:

--O state: annealed state, softest, best plasticity.

--H3x: Partial annealing after work hardening (such as H32, H34), the larger the number, the higher the strength (H34 > H32).

Strength ranking (H34 state reference):

5052 > 3004 > 3003 > 1100

Elongation (plasticity) ranking (O state reference):

1100 > 3003 > 3004 > 5052

Application scenarios:

--1100: conductive/thermal conductive parts, food packaging.

--3003: general sheet metal, architectural decoration.

--3004: beverage cans, high-strength building panels.

--5052: Ships, automobiles, corrosion-resistant structural parts.
