Detailed Description

Coated aluminum coil refers to aluminum product that has been treated with a protective or decorative coating. This coating can serve various purposes, including enhancing the material's appearance, providing corrosion resistance, improving durability, and increasing its resistance to wear and environmental factors.

After high-temperature baking, the paint on the surface of coil coated aluminum has high grain, high gloss retention, good color stability and minimal color difference.

Features of Coated Coil:

1. Small Density: The density of aluminum is only about one-third of steel. In the case of same thickness, calculate the final price on square meter basis, they are almost same.

2. Excellent Processability: Due to moderate structural strength of aluminum, it's easy for processing and convenient to installation, which can reduce construction cost.

3. Nice Decoration: Use aluminum for external insulation decoration, it have bright overall visual. With the addition of paint coating process, that make architectural appearance much more colorful and lively.

4. Long Period Of Validity: Because of the outstanding corrosion resistance, the period of validity can reach above 25 years under normal conditions.

5. High Recovery: The recovery rate can reach 85%.

Application of Coil Coated Aluminum:

Coated aluminum coil is used in a wide range of applications, including:

- Building and Construction: Used for facades, roofing, window frames, and doors.

- Automotive Industry: Employed for body panels, trims, and decorative elements.

- Consumer Products: Found in appliances, furniture, and electronic devices.

- Signage: Used for outdoor and indoor signs due to its weather resistance and vibrant colors.

Production process of Aluminum Coated Coil:

The production process of coated aluminum coil mainly includes the following steps:

- Raw material coil input: The unwinder continuously unwinds the coil to ensure that the coil is continuously and stably input into the production line.

- Surface cleaning and chemical treatment: Clean the upper and lower surfaces of the aluminum coil and perform chemical pretreatment to ensure that the paint can adhere firmly.

- Painting: Use a roller coater for painting, including at least two layers of topcoat and primer.

- Paint layer curing: The newly coated coil should be fixed before contacting the next roller to avoid mutual adhesion and damage.

- Finished product output: Ensure that the production line speed is synchronized with the transfer of the finished product coil to complete the finished product output.
