How To Identify The Security Door

1. Ask the seller to show the "Testing Qualification Certificate" of the relevant department to check whether it meets the technical requirements of the national mandatory standard GB17565-1998.

2. Remove the cat's eye, doorbell box or lock handle, and check the internal structure of the door. There should be several reinforcing steel bars in the door, so that the front and rear panels of the door body are organically connected together. It is best to use materials such as asbestos with fire prevention, heat preservation and sound insulation functions as fillers in the door.

3. Check whether the lock adopts a special anti-theft lock that has been tested by the public security department, and whether there is a reinforced steel plate for protection at the installation of the lock.

4. Check the process quality of the product, whether there are welding defects, whether the door leaf and door frame are tightly matched, etc.

5. Weigh the weight of the anti-theft door, and the weight of the regular anti-theft door shall not be less than 40 kg.
