Coated aluminum coils are made of aluminum alloy sheet that have been surface treated and painted at high temperature. Color coated aluminum coils have good corrosion resistance and decorative properties. Coated aluminum coils are widely used in building materials because of their light material, high strength, rust resistance, fire resistance, moisture resistance, mildew resistance and good decorative properties.

Structure of Coated Aluminium Coil
Process of Coil Coating
Coil coating is a continuous, automated process for coating metal before fabrication into end products. The steel or aluminum substrate is delivered in coil form from the rolling mills. The metal coil is positioned at the beginning of the coating line, and in one continuous process, the coil is unwound, pre-cleaned, pre-treated, pre-primed, and prepainted before being recoiled on the other end and packaged for shipment.
Advantages of Coated Aluminum Coil:
High Durability: Our coated aluminum coils are corrosion-resistant, ensuring a longer lifespan.
Aesthetic Appeal: The wide range of colors and finishes enhances the visual appeal of your products.
Environmental Friendly: Our products are eco-friendly and can be recycled.
Easy Maintenance: Minimal maintenance is required to keep the coils in top condition.
- Customization: We offer customized solutions to meet specific project requirements.
Applications of Coated Aluminium Coils:
We use aluminium coils with PVDF coating mostly for creating walls and buildings. The covering makes the aluminium better against different weather conditions. It stops damage caused by the outside environment.
Select high-quality aluminium with PVDF coating that is robust and provides high UV resistance to be used in roofing construction. They are ideal in outdoor applications, guarantee durable service, and assure safety and strength on built structures.
Known for creating great signs and show boards, coated aluminum coil are very unique. The paint makes them look better, blending light and strong toughness. This is what makes them special since no one can do it as well as they can do it.
In contemporary architecture, exterior curtain walls made out of coated aluminum coil are common. This guard shield offers protection to the building, maintaining the beauty it needs and hence surviving the elements and weathering.
Frequently deployed in outdoor applications, coated aluminum coil are just as apt to be applied on interior projects. They are strong and highly finished to produce lovely walls that match different home contents and architectural designs.
Aluminium finished with PE/PVDF coating are perfectly used as panels on ceilings in residential and business buildings. They have a special finish that prevents soiling and fading to keep their beauty long-lasting and with minimal maintenance.
Aluminium sheets coated with PVDF are good enough and are light to carry, and do not demand much strain. This ensures that they can be applied in the manufacture of furniture to be used either outdoors or indoors, and still be appealing to the eyes.
Due to their excellent property of corrosion protection, coated aluminum coil are widely used in the sectors of electronics and household appliances. They are practical, but good-looking, and have functionality and good looks fused.
