Home appliance manufacturing has strict requirements for material appearance, texture, processability, and environmental friendliness. Pre-coated color galvanized steel sheets have become the core material for the outer casings of refrigerators, air conditioners, washing machines, and other home appliances. Their coating features uniform and delicate colors, meeting the diverse appearance design needs of home appliance products. Meanwhile, the smooth surface is easy to clean, aligning with the characteristics of home appliance usage scenarios.

In terms of processability, the sheets exhibit good flexibility, enabling easy bending, stamping, and other forming processes to adapt to the complex outer shell structures of home appliances. After forming, the coating is resistant to peeling and scratching. Compared with traditional on-site painting, the pre-coating process avoids volatile pollutant emissions, better meeting environmental protection requirements. It also eliminates the need for painting equipment investment in home appliance factories, reducing production energy consumption by 15%-20%. The dual protection of the galvanized layer and coating further enhances the corrosion resistance of home appliance casings, extending product service life.
