Moisture and rust prevention: Although copper doors have good corrosion resistance, attention should still be paid to moisture and rust prevention. In humid environments, desiccants can be placed at the bottom and around the door to prevent moisture accumulation.

Lock maintenance: Regularly check the flexibility of the lock, add an appropriate amount of lubricating oil, and ensure the normal operation of the lock. If any problems are found with the lock, it should be replaced or repaired in a timely manner to ensure the safety of the door.

Avoid collision: During use, avoid collisions between the door and hard objects to prevent deformation or damage to the door. If the door is slightly bumped, it should be repaired in a timely manner to prevent the damage from expanding.
