Product Category
Color coated aluminum coil is a high-quality, pre-painted aluminum product that is produced through a continuous coating process. This process involves applying one or more layers of organic paint to aluminum coils, which are then baked and cured to form a durable, colorful, and protective coating. This type of aluminum coil is widely used in various industries due to its aesthetic appeal, lightweight, and excellent corrosion resistance.
These color coated coils are primarily used in the construction industry for applications such as building roofs, walls, and steel structure plants. They are also widely employed in the manufacturing of home appliances, purification and clean plants, and other industrial fields. The product’s versatility makes it suitable for a variety of uses, ensuring both aesthetic appeal and functional durability.
Commonly used specifications for color coated sheet coils range in thickness from 0.2mm to 1.0mm. The typical domestic widths are 1000mm and 1200mm, while the main export dimensions include 940mm, 1200mm, 1219mm, and 1250mm. These variations in size cater to different market needs and application requirements, providing flexibility for diverse project specifications.
Coating Types
1. Polyester (PE): Known for good adhesion, rich colors, and moderate cost, it offers decent formability and outdoor durability with medium chemical resistance.
2. Silicon Modified Polyester (SMP): Offers enhanced film hardness, abrasion and heat resistance, and good exterior durability. It has medium cost and general flexibility.
3. High Durability Polyester (HDP): Provides excellent color retention, UV resistance, and exterior durability. It has good film adhesion and offers excellent cost performance.
4. Polyvinylidene Fluoride (PVDF): Known for exceptional color retention, UV resistance, and outdoor durability. It also offers excellent solvent resistance and dirt resistance, though it comes at a higher cost and limited color range.
