Tips for identifying good and bad security doors

The easiest way is to knock on the security door with your hand, the sound sounds solid, which can indicate that the thickness of the steel plate is enough, and the filling is real. If the sound sounds "poof", it means that the thickness of the steel plate is not enough. Locks are mostly just a façade.

2. Whether the deadbolt is extended or not, the main lock should be able to be divided into 3 gears (1 gear, small tongue out; 2nd gear, main tongue out; 3 gears, the main tongue is locked, and the auxiliary locks are all extended).

3. How many auxiliary locks are there, and whether they are automatically interlocked (the good ones should be able to extend from the upper and bottom parts of the door).

Most doors also have rubber seals embedded in the door frame, which makes a screeching metal crash sound when the door is closed.
