Maintenance of doors and fans: Clean soft cloth is often used to wipe the dirt on the doors and fans against theft. Attention should be paid to ensure that the doors are dry and avoid sunshine and rain. Replastic sheet products should protect the plastic film to avoid scratching; sprayed sheet products to avoid water or other difficult to remove dirt or corrosive substances, in order to prolong the service life of anti-theft doors.

It is suggested that a protective film should be installed on the plastic plate after finishing, or a layer of film will be covered on the sprayed sheet.
