1.What are the advantages of using color coated coils outdoors?
Coating protection: The organic coating on the surface of the color-coated coil (such as polyester PE, fluorocarbon PVDF) has excellent UV resistance and can maintain bright colors for a long time (anti-fading), and the coating is tightly attached to the substrate, which can isolate moisture, oxygen and pollutants, and prevent the substrate (mostly galvanized steel plate) from rusting and corrosion (especially suitable for rainy, coastal and other high-humidity areas).
Substrate support: The substrate is mostly galvanized steel plate or galvanized aluminum-magnesium alloy plate, which has a certain anti-rust ability, and forms a "double protection" with the coating, which greatly extends the service life of the billboard (usually up to 10-15 years, much higher than the 3-5 years of ordinary painted steel plate).
2.What are the advantages of the color characteristics of color coated coils?
Multiple colors available: The coating can be customized into various pure colors such as red, yellow, blue, black, and white, or the visual impact can be enhanced through matte, high gloss, metallic and other processes (such as high saturation red for warning billboards, and metallic silver to enhance the sense of technology).
High color stability: The color difference of high-quality color-coated coils (such as fluorocarbon coatings) is strictly controlled, and it is not easy to fade or change color after long-term use, ensuring that the billboard maintains a unified visual image for many years (avoiding the influence of mottled colors on brand display).
3.How does the processing performance of color coated coils adapt to billboards?
Easy to cut, bend, and punch: The base of the color-coated coil is a low-carbon steel plate with good plasticity. It can be cut by a shearing machine, formed by a bending machine, and pressed into waves or three-dimensional patterns by a tile press, and quickly processed into various complex shapes (such as billboard frames, three-dimensional letters, and curved panels).
Suitable for mass production: Color-coated coils are mostly supplied in coils, with a length of up to tens of meters. They can be efficiently produced through continuous processing equipment (such as rolling machines and laminating machines), reducing the processing cost of each piece, and are especially suitable for the production of unified billboards for chain brands.
4.What is the comprehensive cost of color coated coils?
Low cost of raw materials: Color-coated coils use ordinary steel plates as substrates, and the coating cost is much lower than that of all stainless steel or aluminum plates. The unit price is only 1/3-1/2 of that of stainless steel plates, which greatly reduces the material investment of large billboards.
Low maintenance cost: The anti-corrosion and anti-aging properties of the coating reduce the frequency of later rust removal and repainting, especially in outdoor environments, and almost no frequent maintenance is required (compared to ordinary steel plates that need to be painted once a year, color-coated coils can last for 5-10 years without obvious damage).
5.What additional functions does color coated steel coil have when used as a billboard?
Graffiti: Some color-coated coils can be coated with special coatings (such as anti-graffiti coatings) to facilitate the cleaning of graffiti on the advertising surface, which is suitable for urban street billboards.
Heat insulation, flame retardant: By selecting color-coated coils with flame retardant coatings or composite insulation layers, they can be used in scenes with high temperature or high fire protection requirements (such as gas station billboards).
