Pre-painted aluminum coil is aluminum coil painted with color. Commonly used are PVDF painted aluminum coil and PE painted aluminum coil. PE painted aluminum coil is made of monomers containing ester bonds in the main chain as monomers, and there are matt surface and bright surface. Pre-painted aluminum coil can endure outdoor ultraviolet radiation, wind and rain, and is quite durable. PVDF pre-painted aluminum coil is combined with fluorine / carbon bonding, and the performance is more stable, the product has extraordinary abrasion resistance and impact resistance, especially in extreme weather and severe weather. It can resist long-term fading and ultraviolet radiation.

Color coated aluminum coils is a popular new type of material. The commonly used grades of pre-painted aluminum coil is 1060/1100/3003/3004/5052. The size range is 0.25 ～ 2.50mm thickness and 1600mm width. It is widely used in aluminum-plastic panels, aluminum veneers, aluminum honeycomb panels, aluminum ceilings, roof surfaces, cans, electronics, interior decoration, road signs, etc. Its performance is very stable and not easy to be corroded. The surface layer can be guaranteed for a lifetime of 30 years if after special treatment.

What factors determine the price fluctuations of pre-painted aluminum coils? The price is mainly composed of the price of aluminum ingots and processing fees. The price of aluminum ingots is based on the daily published price, and for processing fees, even for the same product, different manufacturers’ quotes will vary. The main factors that determine processing costs are alloy series, paint thickness, and paint quality. Different alloy series, different paint thicknesses, and quality of paint all affect the processing costs of color coated aluminum coils.
