Colored aluminum plates, also known as pre - painted aluminum sheets, are a popular choice in various industries. They are made by coating high - grade aluminum substrates with one or more layers of organic paint, resulting in a product that combines the benefits of aluminum with the aesthetic and protective qualities of the coating.
Alloy Series | Main Characteristics | Common Applications in Colored Plates |
---|---|---|
1000 | High purity, excellent corrosion resistance, good formability | General - purpose applications, decorative items where formability is key |
3000 | Aluminum - manganese alloy, good workability, moderate strength | Construction for roofing and siding, general sheet metal work |
5000 | Aluminum - magnesium alloy, high strength, very good corrosion resistance | Marine applications, automotive parts, structures in corrosive environments |
The paint coatings used on these plates are usually either polyester (PE) or polyvinylidene fluoride (PVDF). PE - coated plates are more cost - effective and suitable for general - use applications. They offer a good range of colors based on the RAL color card. PVDF - coated plates, on the other hand, are more expensive but provide superior durability, weather resistance, and colorfastness. The paint coating thickness typically ranges from 10 - 60 μm, with coating styles like 2/1 (two - coat, one - bake) or 2/2 (two - coat, two - bake).
In the construction industry, colored aluminum plates are extremely versatile. They are used for exterior wall decoration, providing an attractive and durable finish. Their weather resistance ensures that they can withstand various climate conditions, including wind, rain, and temperature fluctuations, without bending, deforming, or fading. For example, in commercial buildings, colored aluminum curtain walls not only enhance the building's aesthetic appeal but also offer long - term protection. They are also used for roof panels, where their light weight reduces the structural load. In residential construction, they can be found in partitions, ceilings, and even as insulation boards due to their low light absorption and heat insulation properties.
Colored aluminum plates are used in the transportation sector, particularly in the interiors and exteriors of vehicles. In the automotive industry, they are used for car interiors, such as door panels and dashboard components, providing a lightweight yet durable solution. For trains and airplanes, colored aluminum sheets are used for interior trims, luggage compartments, and sometimes even for external body parts. Their corrosion resistance is especially important in marine transportation, where they are used for ship interiors and some exterior fittings.
Home appliance manufacturers often use colored aluminum plates for making appliance shells and internal components. For instance, in refrigerators and air conditioners, these plates offer a combination of light weight, corrosion resistance, and easy formability. They can be easily shaped into the required designs, and their attractive appearance enhances the overall look of the appliances.
In the packaging of food and beverages, colored aluminum plates are utilized for their good sealing and preservation properties. They protect products from external environmental factors such as moisture and oxygen, helping to extend the shelf life of the products. Additionally, their light weight makes them a cost - effective option for transportation, reducing fuel consumption.
