Color Coated Aluminum Coil Complete Guide: Everthing You Need To Know about Color Coated Aluminum Coil
As one of the most common aluminum materials, color-coated coils and sheets are widely used in various industrial projects. With excellent performance and cheap price, color-coated aluminum coils are recognized as the optimal choice for most people.
What is a Color-Coated Aluminum Coil?
The color-coated aluminum coil is a new type of building material that has risen rapidly in the world in recent decades. It is refined by chemical pretreatment, initial coating, and fine coating on a continuous unit. The coating quality is more stable and ideal than the quality of single-piece spraying or intercalating on the formed metal surface. With the increasing requirements for color steel quality, high-quality color-coated coils came into being, and the market demand continued to expand. The color-coated coil is a composite material, also known as a color-coated steel plate, which is made of strip steel after continuous chemical treatment such as surface degreasing and phosphating on the production line, and then coated with organic coatings and baked. Color-coated coil is characterized by formability, weather resistance, and strong coating adhesion, and can maintain color novelty for a long time.
Coating Types of Color-Coated Aluminum Coil
Finishing Coat
Commonly used finishing coats are polyester, silicon-modified polyester, and polyvinylidene difluoride. There are some differences in hardness, flexibility, and corrosive resistance between different finishing coats. Polyester is currently the most common coating material. Although the durability is relatively average, the hardness and flexibility of polyester coating are performing very well. If you’re looking for some durable coils, coils made with silicon-modified polyester are your best choice. Polyvinylidene difluoride shows good performance in hardness and durability, but it’s not flexible and more expensive than other materials. For more details, you can consult our professional manufacturers on Bestsuppliers.
Base Coat
The commonly used base coats are epoxy and polyester. Epoxy material binds well to the substrate and is resistant to corrosion, but not as flexible as other base coats. Polyester has good adhesion to the substrate and excellent flexibility, but corrosion resistance is not as good as epoxy.
Thickness of Coating
The corrosive resistance of the color-coated coil is closely related to the coating thickness. The appropriate coating thickness should be determined according to the environment, service life, and durability.
Gloss of Coating
The coating gloss is mainly selected according to the use. For example, Household appliances with color coat coils usually choose high gloss.
Coating Hardness
Coating hardness is the ability of coating resistance to scratch, friction, collision, depression, and other mechanical effect. The scratch resistance, wear resistance, and other properties are closely related to the color-coated coil, mainly based on the use, processing mode, storage, and transportation to choose from.
Materials of Color-Coated Coil
There are various materials of color-coated coils for you to choose from. Every material has its advantages and disadvantages. You can refer to the following table.
Materials | Advantages | Disadvantages |
| PE, Polyester | Good adhesion; Easy to process | UV resistance is not ideal |
| SMP, Silicone Modified Polyester | Excellent color retention and heat resistance | Molding property is not ideal |
| PVC Plastisol | Good water resistance and chemical resistance | Relatively poor environmental properties |
| PVDF | Good corrosive resistance and color retention | Expensive |
Surface Treatment Technology of Color-Coated Coil
The improvement of surface treatment technology is one of the reasons why color-coated coils become more and more popular. There are some surface treatment processes, such as passivation treatment. In brief, the process is to put a layer of organic film on the surface, which will protect the surface away from moisture and improve the adhesion and anti-corrosion performance. Passivation treatment is mainly used in conventional galvanized coatings.
Application of Color-Coated Coils
- Color-coated coil is used in the construction industry.
In the construction industry, any board may play an important role. Colored boards like color-coated coils are also commonly used in the construction industry. Bestsuppliers has color-coated coil for sale at cheap wholesale price. Color rolls can also formulate different production standards according to the requirements of different construction industries, as well as the requirements of different construction projects for coating and color. - The color-coated coil is used in the decoration of doors and windows.
The color-coated coil is also suitable for the decoration of doors and windows, especially the rolling shutter doors or ceilings of some houses that can be decorated with the color-coated coil. Color-coated aluminum coil has a good decorative effect in the door and window industry and can make doors, windows or ceilings have a long service life. - The color-coated coil is used in the household appliance industry.
The household appliance industry is also the main industry of color-coated sheets because some refrigerators and washing machines will use color-coated sheets. More specifically, the door shells and side panels of refrigerators, doors of some freezers, and the shells of washing machines are composed of color-coated boards and other materials. - Color-coated coil is used in purification projects.
Color-coated coil, stainless steel, and other materials are used as the composite plate of the surface material. Because of its unique dustproof, antistatic, antibacterial, and other effects, it is widely used in medicine, electronics, medicine, food, biology, aerospace, precision instrument manufacturing, and scientific research. Also, it has been widely used in the field of purification engineering with high indoor environment requirements. You can contact our suppliers for high-quality color steel coils here!
How to Choose Color-Coated Coils?
A lot of people who purchase color-coated coil can not recognize what is good color-coated coil, because it’s hard to see the difference from the surface between the good one and the bad one. Here are some tips for you to choose quality color-coated aluminum coils. Firstly, Choose the inorganic pigment. This kind of paint has a better ability to heat reflection, which will extend the service life of the coating. Also, regarding the colors of the coil, light color is better than dark colors as the galvanized coils with dark color are easy to fade when exposed to ultraviolet light. For the materials of color-coated aluminum coils, you can choose according to your needs.
Conclusion
Finding suitable color-coated coils needs to consider many aspects, like coating types, materials, and colors. If you want some useful suggestions from the expert, please contact us on the Bestsuppliers platform.
