The color-coated coil products are classified as polyester-coated aluminum coils (PE) and fluoropolymer-coated aluminum coils (PVDF). Polyester-coated aluminum coils are a type of UV-resistant coating. Polyester resin is made from high molecular polymers with ester bonds in their main chains as the monomers, with the addition of alkyd resins and UV absorbers. Depending on the glossiness, they can be divided into matte and high-gloss series.
It is particularly suitable for use in interior decoration and advertising boards. The fluorocarbon-coated aluminum coil is made by mixing fluorine vinyl acetylene as the basic monomer with fluorocarbon resin, pigments, alcohol ester solvents, and additives. After being baked at high temperature to form the film, the molecular structure of the coating is tight, and it has extremely strong weather resistance. The fluorocarbon coating can be divided into traditional fluorocarbon coating and nano-fluorocarbon coating according to the surface film formation structure. It is particularly suitable for interior and outdoor decoration in public places, commercial chains, exhibitions, and advertising displays.
The colored coated sheet is coated with 55% aluminum-zinc alloy, which has excellent anti-corrosion properties. Its service life is more than four times that of ordinary galvanized steel sheets. It is a replacement product for galvanized sheets.
Product features of the color-coated coil: It has excellent durability, with a longer lifespan compared to galvanized steel plates in terms of corrosion resistance; it has good heat resistance, less prone to discoloration at high temperatures compared to galvanized steel plates; it has good heat reflection properties; it has similar processing and spraying performance to galvanized steel plates; it has excellent welding performance.
With excellent performance-price ratio, durable performance and highly competitive prices, galvanized zinc alloy steel has been widely used by architects, engineers and manufacturers in industrial buildings, steel structures and civil facilities, such as garage doors, eaves troughs and roofs.
