In today’s modern architecture, the use of color-coated materials has become increasingly popular. One such material that stands out is the color-coated aluminum coil. With its ability to enhance the aesthetics and durability of various applications, this coil has become a preferred choice for architects and designers alike. In this blog, we will delve into the structure of color-coated aluminum coils, explore the coating thickness involved, and discuss the advantages they offer.
What is Color-Coated Aluminum Coil?
Simply put, the color-coated aluminum coil undergoes a meticulous process involving cleaning, chrome plating, roller coating, baking, and various other techniques. This results in a surface coated with an array of vibrant paint colors, adding versatility and visual appeal to the aluminum coil. The careful application of paints ensures a long-lasting and lustrous finish.
The Structure of Color-Coated Aluminum Coil:
To create a formidable structure, the color-coated aluminum coil typically consists of various layers. Firstly, a layer of primer is applied to enhance adhesion while preventing corrosion. Next, multiple coatings of paint are applied, each contributing to the desired color, texture, and gloss. The final layer is often a protective coating that safeguards the surface against external elements. This meticulous structure ensures optimal durability and aesthetic appeal.
Coating Thickness:
The thickness of the color coating is a crucial factor that determines the lifespan and overall quality of the color-coated aluminum coil. The industry standard for coating thickness is measured in microns. Typically, the thickness of the primer layer ranges from 5-7 microns, while the topcoat layer thickness varies between 20-30 microns. Opting for a high-quality coil with appropriate coating thickness not only enhances its visual appeal but also ensures longevity and resistance to fading or chipping.
Types of Color-Coated Aluminum Coils:
Color-coated aluminum coils can be categorized based on their processing and raw material composition. Primarily, they can be divided into surface coating paint and primer. The coating paint raw materials determine the performance, appearance, and maintenance requirements of the coil. Polyester (PE) coated aluminum coils provide excellent color consistency, affordability, and versatility. Fluorocarbon (PVDF) coated aluminum coils, on the other hand, offer exceptional durability, weather resistance, and UV protection. Additionally, there are situations where one side is coated with fluorocarbon and the other side with polyester, catering to specific project demands. The presence of fluorocarbon on both sides ensures unparalleled protection and longevity.
Benefits of Color-Coated Aluminum Coils:
When it comes to architectural applications, color-coated aluminum coils offer a plethora of benefits. Firstly, their vibrant and customizable finishes expand the creative possibilities for architects and designers. The extensive range of colors and textures allows for seamless integration into various design aesthetics. Moreover, due to the advanced coating process, these coils provide exceptional weather resistance, UV protection, and corrosion resistance, making them suitable for exterior applications in diverse climates.
Conclusion:
The structure and coating thickness of color-coated aluminum coils play a vital role in determining their quality, durability, and aesthetic appeal. With the availability of various raw materials and coating technologies, these coils offer architects and designers immense creative potential. Their vibrant finishes, exceptional weather resistance, and cost-effective nature make them an ideal choice for enhancing the visual appeal and longevity of architectural projects. Embracing color-coated aluminum coils not only adds a touch of modernity to structures but also ensures sustainable and long-lasting solutions in the construction industry.
Post time: Mar-10-Color coated aluminum coil features excellent corrosion resistance, great durability, and light weight. It is widely used in public buildings, power plants, steel mills, chemical industries, and other industries. As a metal products supplier, we have prepainted aluminum coil with different aluminum alloys as the base metal. And the popular coating is PE and PVDF. The thickness available is from 0.2 mm to 2.0 mm and the max width is 1,500 mm. More than that, you can choose different colors and patterns according to your needs and preference.
It is widely used in aluminum-plastic panels, buildings, aluminum shutters, composite panels, ceilings, cans, and electronic products.
Goto Jinxinda to know more.
Construction and decoration: such as roofing panels, aluminum-plastic composite panels, interior aluminum panels, shutter doors, garage doors, ceilings, curtain walls, wall claddings, steel structures, elevators, etc.
Electronic products and household appliances: electrical shells, computer panels, lighting, solar reflectors, water heater, water tank shells;
Traffic signs and automobiles: traffic signs, vehicles interior panel, ship decoration, advertising display boards, luggage;
Furniture: metal furniture, kitchen cabinets, various countertops, partitions, pipeline insulation, etc.
As we know, color-coated aluminum coil uses aluminum as the substrate. The aluminum itself has strong corrosion resistance. The aluminum molecules combine with oxygen to form an aluminum oxide film, which covers the surface of the aluminum. It can prevent the aluminum from further oxidizing. Plus with the paint, generally PVDF or PE paint, the color coated aluminum is very durable to use.
The density of aluminum alloy is 2.73 kg/m3, which is one-third of that of steel. So it is light in weight, which greatly reduces the load on the support structure. Therefore, the color coated aluminum is widely used in airports, stations, stadiums, and other large-span construction fields.
Due to the addition of metal components such as magnesium and manganese, the strength, and rigidity of aluminum alloy are greatly enhanced. And its load-bearing performance is improved. The paint will not influence the strength. So the color coated aluminum also features high strength and good rigidity.
Color coated aluminum is easy to process and it can be bent into various roof shapes to meet customers’ needs. Different climates, wind pressure, temperature, humidity, and other factors will not cause bending, deformation, expansion, etc.
Color coated aluminum coils are available in different colors and custom patterns, such as wood grain and stone grain. The beautiful appearance can meet the different needs of architectural style and design requirements.
The paint aluminum coils are made by coating and baking at high temperatures. So it has high gloss retention and good color stability. The polyester-painted aluminum coil is guaranteed for 10 years, and the PVDF painted aluminum coil is guaranteed for more than 20 years.
According to the coatings, there are PE-coated aluminum coils and PVDF-coated aluminum coils.
The polyester (PE) coating can firmly attach to the aluminum surface through repeatedly baking and coating. It is a kind of anti-UV ultraviolet coating. Also, it has rich colors with good gloss and smoothness. The coating can protect the base metal from ultraviolet radiation, wind, rain, frost and snow. Especially, it is suitable for interior decoration and advertising boards.
PVDF coating has excellent abrasion resistance and corrosion resistance. It also has superior weather and UV resistance, especially in harsh climates and environments. Besides, it will maintain its color and luster after 20 years outdoors. Therefore, it is suitable for public buildings, indoor and outdoor decorations, commercial uses, exhibition advertisements, etc.
In addition, our color coated aluminum plates are available in a variety of aluminum grades, such as: series, / series, series.
Color-coated aluminum coil has rich colors and patterns. And you can choose matte or glossy surface, smooth or embossed finishes. So it is versatile in residential, commercial, and public buildings. we have both pre-painted aluminum sheets and coils for sale.
