1. Avoid contacting the door surface with corrosive materials such as acids or alkalis, as this can damage the protective coating and lead to discoloration or peeling of the paint. 2. The lock is a critical component of the door, and its smooth operation directly affects how easily the door opens and closes. Never hang heavy objects on the handle, as this may cause unnecessary stress or damage. 3. During rainy weather, make sure to remove any water that accumulates under the door’s threshold promptly. Prolonged exposure to rainwater—especially acidic rain—can damage the protective film, leading to rust and deterioration of the door's structure. 4. For doors with painted or powder-coated surfaces, it's important to avoid scratching or damaging the outer layer. Any damage to the protective coating can expose the underlying material to moisture and corrosion, reducing the door's lifespan and performance. 5. Regular maintenance of the door hinges is essential for smooth and consistent operation. Apply lubricant periodically to ensure the hinges remain flexible and free from sticking or noise. 6. If the door hinge becomes misaligned or sags, check the evenness of the hinge and adjust it if necessary. Proper alignment ensures the door functions correctly and prevents long-term wear and tear. By following these simple guidelines, you can significantly extend the life of your door and maintain its appearance and functionality over time. Always inspect your door regularly and address any issues early to avoid more serious problems down the line. Micro Flowrate Mechanical Diaphragm Dosing Pump
