Essentials for Using Non-paint Doors
     Post Date：2009-12-30     
        Avoid hanging heavy things on the door or damaging or scratching the door. To prevent any damages, do not open or shut the door very hard or open the door leaf to an excessive angle when opening or closing the door.
 
 

　　To prevent the lock from changing color, do not unlock the door with hands wetted with water or other solutions.When unlocking the door or turning the lock handle, avoid any great strength that shortens the service life of the door. Tighten the hardware including the hinges and lock once they become loose. When the lock turns uneasily, a proper amount of pencil lead power can be fed into the keyhole.
