First, the use of high-quality substrates is becoming increasingly important. The surface quality, plate shape, and dimensional accuracy of these substrates are now subject to stricter requirements. For outdoor applications, products like small zinc flower hot-dip galvanized steel coils, zinc-free flat hot-dip galvanized steel coils, and zinc alloy hot-dip coils have seen a rise in demand. On the other hand, for indoor use, electro-galvanized steel coils, foil cold-rolled sheets, and aluminum coils are widely utilized. Second, the pretreatment process and the pretreatment liquids have been continuously improved. The equipment used is more compact, cost-effective, and efficient. The mainstream processes are being refined, leading to better stability, corrosion resistance, and environmental performance of the pretreatment solutions. Third, there is a growing focus on developing new types of coatings. Improvements have been made to general polyester, polyvinylidene fluoride (PVDF), and plastisol coatings, resulting in enhanced color reproducibility, UV resistance, and sulfur dioxide resistance. Additionally, coatings with pollution-resistant, heat-absorbing, and functional properties are being developed to meet diverse needs. Fourth, the production equipment has become more advanced and complete. New welding machines, roller coating systems, full curing ovens, and state-of-the-art automation tools are now commonly used in the industry, improving efficiency and product consistency. Fifth, cold embossing technology is gaining popularity due to its lower cost compared to hot embossing. It offers aesthetic appeal, three-dimensional effects, and high strength, making it a promising trend in modern manufacturing processes. Sixth, there is a strong emphasis on product diversification, functionality, and premium quality. Innovations such as deep-drawing color-coated panels, "Pomelo peel" color-coated panels, anti-static color-coated panels, pollution-resistant color-coated panels, and high-heat-absorption color-coated panels are now being developed to cater to different market demands.
