Can anyone tell me how to choose a security door?

Look at the indicators on the Internet in detail, and understand that my 3 will not fool people.

Choose an anti-theft door to look at three indicators.

1.Brand: Panpan, Wang Li, Meixin, Buyang, etc.

2.Anti-theft door grade: A, B, C, D, grade A is the best. The regular grade mark is on the door frame inside the door, and it is best to have a qualified code (the one on the door leaf is fake), and the grade describes the thickness of the steel plate of the anti-theft door and door frame.

3.The level of the door lock: A B ultra B.

Ultra B is the best. Personally, I think that super B-level locks are necessary, and the national standard anti-technical opening of B-level locks (key indicators of lock anti-prie) is "5 minutes", and the "super B-level anti-technical opening time" is 180 minutes. It's like the difference between Audi and Alto.

I personally recommend Wang Li, the only company that makes doors and locks, and the quality of door locks is good. All doors are ultra-B locked.

If you are strong, you can take a look at Panpan's Jingjing (Panpan is a B-level lock, you must recognize it), and Jingjing is also super B-level, but the price is too high, and the door is still very good.

Don't choose a lock structure that is too simple and too complex, these security features are not good. This is what the lock seller said.
