Teach you to identify and buy genuine "anti-theft doors"

Having a reliable anti-theft door means that your home security is guaranteed, but what kind of door can be regarded as a genuine "anti-theft door"? How should ordinary consumers buy it? There are a lot of fame here.

Entry door is not equal to anti-theft door
In addition to anti-theft doors, there are steel entry doors, anti-pry doors, and armored doors on the market. In fact, these are not anti-theft doors.

On the surface, the metal entrance door with the same appearance is the same as the security door, but the internal quality is very different. The entrance door does not have the anti-theft function in practical applications.

Inspection certificate
The real anti-theft door must pass the test by the statutory testing agency, and have the safety technology prevention product approval certificate issued by the safety technology prevention department of the provincial public security department (bureau) where the production enterprise is located.

The “General Technical Conditions for Anti-theft Security Doors” formulated by the Ministry of Public Security clearly states that anti-theft doors refer to doors that can resist abnormal opening under certain conditions within a certain period of time, and have special locks and anti-theft devices. In other words, a door that cannot be opened using ordinary tools such as chisels, screwdrivers, crowbars, and portable electric tools such as hand-held drills within 15 minutes is considered a real "security door".

Good door with good lock
Good anti-theft doors also need to be equipped with locks. At present, the anti-theft door locks on the market are equipped with two types of anti-theft door locks: one is the A and B key anti-theft door lock, and the other is the smart door lock. The anti-theft door using the A and B keys provides convenience for the new house decoration households. The decoration workers use the A key to open the door; after the decoration, the owner only needs to insert the B key into the lock hole, and the A key is scrapped.
