In the field of home appliance appearance decoration, the reasons why coated steel plates are more popular than color-coated plates can be summarized as follows:
1. Appearance diversity and aesthetics
– Rich design options: By covering the surface of the steel plate with a polymer film (such as PET, PVC), the coated steel plate can easily achieve complex patterns such as wood grain, stone grain, metal brushing, and even high gloss or matte effects, meeting the personalized needs of modern home appliances.
– Color stability: The printing process of the film avoids the color difference problem that may occur in the spraying of color-coated plates, and it is not easy to fade after long-term use.
2. Excellent surface properties
– Scratch resistance and wear resistance: The thickness and hardness of the coating layer are usually better than the color coating, which can effectively resist scratches and wear in daily use.
– Corrosion resistance: The film layer isolates corrosive substances such as moisture, acid and alkali, protects the substrate, and prolongs the service life. If the coating of the color-coated plate is damaged, it is easy to cause rust.
3. Processing convenience and cost-effectiveness
– Forming adaptability: During stamping, bending and other processing of coated steel plates, the flexibility of the film can reduce the risk of surface cracking and reduce the scrap rate; the coating is prone to cracks during color-coated plates processing and requires additional treatment.
– High production efficiency: The lamination process is mostly completed by one-time lamination, while color coating requires multiple coating and drying processes, which consumes more energy and time.
4. Easy to clean and maintain
– Smooth surface: The surface of the coated steel plate is dense and non-porous, and it is not easy to adhere to oil stains and fingerprints, which is easy to clean; if the surface of the color-coated plate is matte or textured, it may be more prone to dust accumulation.
