FEVE Aluminum Composite Panel
Click here to get more.
This kind of panel comprises a polyethylene core between two aluminum skin, the front surface is coated with FEVE paints. Its excellent weather resistance is more suitable for the building’s exterior decoration and curtain wall projects. When compared with the normal PVDF coating, this type of Aluminum composite panel can accept the order of Glossy colors.

Applications
Building exterior cladding & curtain wall projects: FEVE coated ACP for outside use, excellent weatherproof function. And recommend to use panel thickness 4mm or 5mm, Aluminum skin thickness 0.30mm or 0.40mm or 0.50mm.
Aluminum coil coating is a kind of polyester coating coil. It has the characteristics of high weather resistance, which can effectively improve the anti-ultraviolet ability and prolong the service life of outdoor use.
Painted Aluminium Coil
Painted aluminium coil is a color coating treatment on aluminum coil. Commonly fluorocarbon color coated aluminum and polyester color coated aluminum are widely used in aluminum composite panels, aluminum veneer, aluminum honeycomb panels and so on. Aluminum ceilings, roof surfaces, leftovers, cans and electronic products. Its performance is very stable and not easy to corrode. After special treatment, the surface can reach 30 years of quality assurance. The weight per unit volume is the lightest among metal materials.
painted aluminium coil is treated with various colorful paint coatings on the surface of aluminum coils after washing, chromium penetration, roller coating, baking and other processes.
Coatings applied to Painted aluminium coil and sheets serve a number of purposes, including:
- Protecting the aluminum from corrosion and other types of damage
- Improving the appearance of the aluminum by providing a uniform, smooth finish
- Enhancing the performance of the aluminum in certain applications, such as in the construction or automotive industries
There are several different types of coatings that can be applied to painted aluminium coil, including:
-
PVDF (polyvinylidene fluoride) coatings: These coatings provide excellent weathering resistance and are commonly used in architectural and construction applications.
-
Powder coatings: These coatings are made from dry, finely ground resin and are applied to the aluminum using heat. They are known for their excellent corrosion resistance and durability.
-
Anodized coatings: These coatings are formed by an electrolytic process that creates a thin, oxide layer on the surface of the aluminum. Anodized coatings are known for their excellent corrosion resistance and durability.
-
Organic coatings: These coatings are made from a variety of organic materials, such as paints, enamels, or lacquers, and are applied to the aluminum using a variety of techniques, such as roll coating or spray coating. Organic coatings are commonly used for decorative or aesthetic purposes.
In summary, painted aluminium coil is the process of applying a protective layer or coating to aluminum coils or sheets to protect the aluminum and improve its performance in certain applications. There are several different types of coatings that can be applied to aluminum, including PVDF, powder, anodized, and organic coatings.
Advantages of Painted Aluminium Coil:
1. Light texture, easier to form
2. Corrosion resistance Because its surface has a dense oxide film, it has strong adhesion, anti-oxidation, acid resistance, alkali resistance, corrosion resistance, corrosion resistance, and UV resistance.
3. Good temperature resistance, the melting point of aluminum is 660 degrees, and the general temperature does not reach its melting point
4. The board has extremely high strength and can be cut, slit, balanced, drilled, joined, fixed and compressed at the edges.
