(1) Installation of anti-theft doors should be conducted according to the type of door used, utilizing the appropriate installation method.

(2) The door frame of a burglar-proof door can be secured to the wall with expansion bolts, or iron components can be pre-buried in the opening during wall construction, and then welded firmly to the connecting parts of the door frame during installation.

(3) Regardless of the connection method between door frames and walls, there should be no fewer than 3 anchor points on each side, and they should be securely connected.

When installing a burglar-proof door, first ensure it is plumb and level. After measuring the dimensions and finding they are suitable, temporarily secure the door and proceed with alignment and adjustment. Only after verifying there are no errors should you proceed with the anchoring connection.

(5) The sliding doors should be installed with smooth sliding; the swing doors should open easily and close tightly and securely.

(6) Anti-theft devices should be installed between the door frame and door leaf, or at other locations.

(7) All hardware components such as handles, locks, and peepholes on the security door must be complete; for multi-functional security doors, devices like password protection locks, electronic alarm password systems, and doorbell intercoms must be effectively and perfectly installed.
