What is color color-coated aluminum coil?
Color-coated aluminum coils are also called colored aluminum coils. Color-coated aluminum sheets are produced by cutting color-coated aluminum coils with shearing equipment, or by spraying plain aluminum sheets. Color-coated aluminum strips are produced by slitting color-coated aluminum coils with slitting equipment.
Color-coated aluminum coils are aluminum coils that are coated with paint coatings of various colors on the surface after cleaning, chromating, roller coating, baking, and other processing techniques.
Color-coated aluminum coils and sheets are used in the construction industry, interior decoration, electronic product casings, road signs, and other fields.

PE(polyester) color coated aluminum coil and sheet
After the surface of the aluminum coil is baked and painted multiple times, the polyester-coated aluminum coil formed on the surface of the aluminum coil is called a polyester color-coated aluminum coil.
PE (Polyester) is an anti-UV coating that not only has protective and decorative properties but also has good gloss and smoothness, which increases the corrosion resistance and durability of items. It is especially suitable for interior decoration and advertising boards.
PVDF(fluorocarbon) color coated aluminum coil and sheet
Fluorocarbon coating refers to PVDF resin, which generally refers to coatings made from homopolymers of vinylidene fluoride or copolymers of vinylidene fluoride and different small amounts of fluorinated vinyl monomers.
Fluorocarbon color-coated aluminum coils have good gloss, wear resistance, weather resistance, and no color difference. In harsh climates and environments, they have longer-lasting fading resistance and UV resistance than PE-coated aluminum coils. The service life reaches more than 20 years.
Fluorocarbon coatings can be divided into two categories based on their floor film-forming structures: ordinary fluorocarbon coatings and nano-fluorocarbon coatings.
Fluorocarbon color-coated aluminum coils are particularly suitable for indoor and outdoor decoration in public places, decoration and display of chain enterprises, exhibitions, etc., such as roof corrugated panels, fireproof veneer panels, aluminum ceilings, blinds, rolling shutters, garage doors, lighting, furniture, electronic appliances, and other different places.

HDPE color coated aluminum coil
HDPE is the abbreviation of High-Density Polyethylene. The coating of HDPE color-coated aluminum coils uses high-density polyethylene resin as the base material. It is processed by a professional coating process to form a uniform and smooth coating.
This coating has good weather resistance and can resist the erosion of ultraviolet rays, oxidation, rain, and other external environmental factors, maintaining the long-term beauty of the aluminum coil.
Imitation stone coated aluminum coil
The imitation stone grain roller-coated aluminum sheet is light in weight. For the same area, the mass of the aluminum veneer is about 1/10 - 1/12 of that of brick wall painting, and 1/15 of the quality of dry-hanging marble and granite curtain walls. It is 15-1/7 that of concrete siding.
The imitation stone grain roller-coated aluminum sheet is a new decorative material based on the aluminum veneer, which is processed through a special roller coating or spraying process to give the aluminum veneer a strong stone three-dimensional effect, which is extremely realistic.
Common stone grain aluminum coils include marble grain aluminum coils and sheets, granite grain aluminum coils and sheets
Wood grain aluminum coil
The wood grain aluminum sheet is coated with a wood grain decorative coating on the surface of the aluminum sheet through spraying, heat transfer, or roller coating. The wood grain on the surface has clear filamentous fine lines or rough simulated wood grain texture. It is rich in color and natural and is an excellent building decoration material.
Imitation wood grain aluminum veneer does not contain formaldehyde, is non-toxic, and does not release harmful gases, so you no longer have to worry about the odor and physical harm caused by paint and glue substances after decoration.
Mirror color coated aluminum coil
The color-coated mirror aluminum coils use 1100, 3003, 3105, and other series of high-purity aluminum-based coils to ensure that the aluminum purity is above 99.8%, the mirror reflectivity is above 85%, and the clarity is above 94%.

PVDF coating vs Polyester coating
The paint preparation and processing cycle of PVDF coating is longer than that of PE coating, so the delivery time of PVDF-coated aluminum coil is later than that of PE-coated aluminum coil.
A detailed comparison between PVDF coatings and polyester coatings, highlighting their differences in chemical composition, durability, color and gloss retention, environmental impact, application, cost, and maintenance.
| Feature | PVDF Coating | Polyester Coating |
|---|---|---|
| Chemical Composition | Contains PVDF resin, known for its exceptional chemical resistance and durability | Contains polyester resin, which is less chemically resistant and durable compared to PVDF |
| Durability | Highly durable, with excellent resistance to UV radiation, chemicals, and weathering | Moderately durable, with good UV resistance but less resistant to chemicals and weathering |
| Color Retention | Excellent color retention, maintains vibrant colors for an extended period | Good color retention, but may fade or chalk over time, particularly in harsh conditions |
| Gloss Retention | Maintains high gloss and sheen over time, making it suitable for architectural aesthetics | May experience gloss reduction over time, particularly in harsh outdoor environments |
| Environmental Impact | Generally more environmentally friendly due to longer lifespan and reduced maintenance | May require more frequent repainting or refinishing, resulting in a greater environmental impact |
| Applications | Widely used in architectural cladding, metal roofing, curtain walls, and high-end outdoor applications | Suitable for general-purpose applications such as appliances, automotive parts, and indoor equipment |
| Cost | Typically higher initial cost due to superior durability and performance | Lower initial cost but may require more maintenance and repainting over time, leading to higher long-term costs |
| Maintenance | Requires minimal maintenance and offers long-term cost savings | May require more frequent repainting or refinishing, leading to higher maintenance costs |
Coating process
Color coating pre-treatment
Before the color-coated aluminum coils and sheets are colored, the plain aluminum coils need to be further processed to make the aluminum coils have better coloring effects.
- Hot water cleaning
- Hot alkali degreasing
- Passivation treatment
Roller coating vs. spray coating
The coating processes for color-coated aluminum coils and aluminum sheets include roller coating and spray coating.
Roller coating refers to the continuous and uninterrupted degreasing, chemical pretreatment, and color coating of aluminum substrates.
Spraying uses the negative pressure generated by compressed air at the spray gun nozzle to spray the paint in the paint container from the paint nozzle to paint the aluminum sheet.
| Feature | Roller coating | Spray coating |
|---|---|---|
| Number of layers that can be coated | Front coating, color display coating | Front coating |
| Primer, the coating between the front coating and the aluminum sheet | ||
| Back coating, anti-corrosion coating on the back of aluminum sheet | ||
| Bake | Twice baked | Bake once |
| Coating film thickness | Uniform thickness | Relatively uneven |
| Color difference | Basically no color difference | Easy to age and appear color difference |
| Supportable experiments | Impact test, cross-hatch test, T value test, solvent resistance test, aging resistance test | Impact test, etc. |
