Anti-theft door with anti-theft lock is playing a key role, can resist abnormal opening in a certain period of time, with security protection and corresponding anti-theft security level of the door.
Second, what is the difference between fire doors and security doors?
1, the main function of fire doors is used for fire protection, so the fire resistance is very strong, so the material used to be highly resistant to burning, high temperature, but also will not release toxic gases, but can prevent the entry of toxic gases. Normally, the exterior appearance of the fire door is very smooth and flat, giving a very generous and flexible feeling, and it is durable, easy to use, safe and reliable.

Security doors are generally resistant to tools such as chisels, screwdrivers, and crowbars that cannot be opened within 15 minutes, and a 615 square millimeter opening in the door leaf, or a 38 square millimeter opening in a 150 square millimeter semicircle at the locking point. In line with the "General Technical Conditions for Anti-theft Security Doors".
