Aluminum Coil is a flat rolled product in an unprocessed state, usually rolled into a coil shape for easy handling and transportation. Coated Aluminum Coil refers to a product that is sprayed on the surface of the aluminum coil, also known as color coated aluminum coil or color coated aluminum coil. After color coating, the aluminum coil can improve the application performance and aesthetics of the aluminum coil in many fields.
Color coated aluminum coil is a deep processed product of aluminum coil.

Although bobine d'aluminium enduit de couleur and ordinary aluminum coil are the same type of products, there are some differences in their characteristics.

Surface treatment

Aluminum coil: Usually in its natural state without any additional surface treatment.
Coated aluminum coil: The surface is coated with an additional coating such as paint, polyester or PVDF (polyvinylidene fluoride).

Résistance à la corrosion

Aluminum coil: Due to the formation of an oxide layer, it naturally has a certain degree of corrosion resistance, but this may be limited by the environment.
Coated aluminum coil: Due to the protective coating, the corrosion resistance is enhanced and it is more suitable for harsh environments.

Appearance

Aluminum coil: Usually has a plain metal appearance.
Coated Aluminum Coil: Available in a variety of colors and finishes, including matte, glossy, and textured, providing aesthetic versatility for different applications.

Durabilité

Aluminum Coil: Durable, but susceptible to scratches and dents.
Coated Aluminum Coil: Coatings can provide additional protection against physical damage, making them more durable in certain applications.

Cost

Aluminum Coil: Typically less expensive due to the absence of an additional coating process.
Coated Aluminum Coil: Typically more expensive due to the additional processing and materials involved in the coating.

Applications

Aluminum Coil: Typically used in industries where additional surface protection or aesthetics are not important, such as general engineering, transport, and construction.
Coated Aluminum Coil: Utilisé dans les applications où l'apparence, résistance à la corrosion, et la durabilité sont importantes, comme les façades de bâtiments, toiture, et design d'intérieur.

Similitudes entre la bobine d'aluminium revêtue et la bobine d'aluminium

1. Substrat: Les deux produits utilisent de l'aluminium comme substrat, garantir les avantages de l’aluminium, comme le poids léger, force, et flexibilité.

2. Processus de fabrication: Le processus de fabrication initial des deux produits, y compris le laminage et le formage, est similaire jusqu'à ce que le revêtement soit appliqué sur la bobine d'aluminium revêtue.

3. Recyclabilité: Les deux produits sont recyclables, thus maintaining the advantage of aluminum as an environmentally friendly material.

4. Poids léger: Both types of coils retain the lightweight characteristics that are unique to aluminum, making them easy to handle and install.

5. Electrical conductivity: Both products retain the excellent thermal and electrical conductivity properties of aluminum, although the coating on coated aluminum coils may slightly affect surface conductivity.

Aluminum coils are widely used in various industries due to their excellent properties, comme le poids léger, durability, and a certain degree of corrosion resistance.
Coated aluminum coils start out as ordinary aluminum coils, but go through an additional process to coat them with a layer of protective material. A variety of colors and finishes are available to enhance visual appeal, and they also increase the coil’s resistance to environmental factors such as UV radiation, moisture, and chemical exposure. Coated aluminum coils are particularly popular in architectural applications, such as curtain walls, roofing systems, and cladding, où l'esthétique et la durabilité sont essentielles.
