Color coated coils are sheets made from cold-rolled steel plates, galvanized steel plates, and other substrates. After surface pretreatment, they are coated with organic coatings and then baked and cured. They are a new type of material that combines the metal properties of the substrate with the chemical advantages of the coating. They are widely used in fields such as construction, home appliances, and transportation, with outstanding core characteristics reflected in six aspects.
Firstly, it has excellent decorative properties and rich colors. Color coated rolls can be customized in various color schemes such as red, blue, gray, and white, as well as imitation textures such as matte, high gloss, wood grain, and stone grain. The coating has strong adhesion, is not easy to fade or peel, and can directly meet the appearance design needs of various scenarios without the need for secondary coating, greatly improving the product’s appearance and adaptability.
Secondly, it has outstanding anti-corrosion and anti rust properties. The substrate has undergone anti-corrosion treatments such as galvanizing and aluminum zinc plating, and the surface organic coating forms a dual protective barrier, which can effectively isolate corrosive media such as air, moisture, acid and alkali. Compared with ordinary cold-rolled and hot-rolled plates, its weather resistance and corrosion resistance have been greatly improved. Its service life can reach 15-30 years in outdoor buildings and humid environments, reducing maintenance costs in the later stage.
Thirdly, the processing performance is flexible and convenient. The color coated roll retains the good plasticity of the metal substrate and can be processed by various methods such as shearing, bending, stamping, rolling, welding, etc. according to needs. It can be made into finished products of different specifications such as roof panels, wall panels, home appliance shells, and car cabin panels. The coating is not easy to crack or peel off during the processing, making it suitable for large-scale production and personalized customization.
Fourthly, it is lightweight, high-strength, and efficient in installation. The thickness of color coated rolls is mostly between 0.15-2.0mm, which is lightweight and covers a large area with a single sheet. It can significantly reduce lifting and transportation costs in construction. The on-site installation process is simple, and the splicing is tight, which can effectively shorten the construction period and improve construction efficiency.
Fifthly, the surface is easy to clean and easy to maintain. The coating surface is smooth and dense, not easy to adsorb dust and oil stains. Daily cleaning only requires wiping with water or mild cleaning agents, without the need for special maintenance methods. It is especially suitable for scenarios that require cleanliness, such as household appliances and public building facades.
Sixth, it has high cost-effectiveness and low overall cost. Although the unit price is slightly higher than that of ordinary bare boards, it comes with protective and decorative layers at the factory, eliminating the need for subsequent painting and anti-corrosion treatment processes and costs. It also has a long service life and low maintenance frequency. From the entire life cycle of production, construction to use, the comprehensive cost is much lower than traditional boards, which is both economical and practical.
At the same time, high-quality color coated rolls also have additional characteristics such as scratch resistance, temperature resistance, and UV resistance. Color coated rolls with different coating types (such as polyester PE, fluorocarbon PVDF, and silicon modified polyester SMP) can meet the specific needs of different scenarios, and are suitable for full range applications from indoor appliances to outdoor high weather resistant buildings. They are efficient and energy-saving materials in modern industrial and construction fields.
