Color Coated Aluminum Coil
Color Coated Aluminum Coil
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 1.2 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.
Uses of Color Coated Aluminum Coil
It is widely used in aluminum-plastic panels, buildings, aluminum shutters, composite panels, ceilings, cans, and electronic products.
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.
Features of Color Coated Aluminum Coil
High Durability
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.
Light Weight
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.
High Strength
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.
Good Plasticity
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.
Great Decorative Effect
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.
Excellent Weather Resistance
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.
Types of Colored Aluminum Sheet
According to the coatings, there are PE-coated aluminum coils and PVDF-coated aluminum coils.
PE-coated aluminum coil
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 Painted Aluminum Coil
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.
Besides, color aluminum is available in a wide range of aluminum sheets, including the 1000 series, 3000 series, 5000 series, etc.
Conclusion
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. At Wanzhi Group, we have both pre-painted aluminum sheets and coils for sale. We also offer value-added services, such as cutting, slitting, profiling, etc. Welcome to contact us for more details.

What Are Features of PVDF Coated Aluminum Coil
Compared with polyester color-coated aluminum coil, PVDF coated aluminum coil is of a longer service life. Generally, the service life of PVDF coated aluminum coil and aluminum plate can reach more than 20 years while the service life of polyester color-coated aluminum coil is usually around 10 years.
It also has strong corrosion resistance and can be generally used in different places such as roof corrugated panels, fireproof veneers, aluminum ceilings, shutters, roller shutters, garage doors, lighting, furniture, electronic appliances, etc.
Fluorocarbon color-coated aluminum coil is a product that uses high-quality fluorocarbon paint to coat the surface of aluminum coil. Fluorocarbon paint has good weather resistance and long service life. It is the first choice for color-coated aluminum coils for outdoor products. Haomei Aluminum chooses quality paints such as Nippon and PPG, which can better ensure the service life of color-coated aluminum coils.
The history of fluorocarbon coatings is relatively short, but it has developed rapidly. The basic component of fluorocarbon coating is fluororesin, which has excellent chemical stability, heat resistance, acid and alkali resistance, flame retardant/fire resistance, aging resistance and self-lubrication.
The PVDF coated aluminum coils is produced by roller coating process. Roller coating is to apply the paint evenly on the aluminum coil through the friction and pressure of the roller. The coating particles are arranged horizontally on the surface of the aluminum coil, which can make the surface of the color-coated aluminum coil smooth and not easy to collect dust.
Another coating method is spraying. Compared with roller coating, spraying sprays the paint on the surface of the aluminum coil through the nozzle, so that the paint particles are arranged vertically on the surface of the aluminum coil, which will make the surface of the pre-painted aluminum coil relatively rough and easy to collect dust.
Roller-coated PVDF coating aluminum coils also have some advantages, such as small surface color difference, easy cleaning and strong scratch resistance. Although the price is relatively high, the cost performance is very high. Especially in harsh climates and environments, it shows long-term resistance to fading and UV resistance.
Quality requirements of PVDF color coated coil
The 60° gloss value of the fluorocarbon coating should be consistent with the contract, and the allowable deviation is ±5 gloss units. As for the dry film harness, it should be ≥1H when it undergoes the pencil scratch test. The dry, wet and boiling water adhesion of the coating should reach grade 0.
After the impact test on the front of the coating, there should be no cracking or falling off, but fine wrinkles are allowed around the depression. After the falling sand test, the abrasion coefficient should be ≥1.6 L/µm. After the coating is tested by hydrochloric acid, there should be no bubbles and other obvious changes on the surface.
