Security doors are now widely used in most homes, known for their sturdiness and effective security features. Below, the editor introduces how to choose the right security door and whether they truly provide防盗 capabilities.

How to Choose a Security Door?
1. Brands: Pan Pan, Wang Li, Meixin, Buyang, and the likes. 2. Security Door Grades: A, B, C, D, with Grade A being the best. The official grade markings are placed on the door frame inside the door, and a valid code (false if marked on the door leaf) indicates the grade. The grade describes the thickness of the steel plate for the security door and door frame. 3. Lock Grades: A/B/Over B. Over B is preferable. Personally, I believe Over B grade locks are essential, as the National Standard for Grade B locks' anti-picking technology takes more than 5 minutes, while Over B locks take more than 180 minutes. It's like the difference between Audi and Ollantay. I recommend Wang Li, a company that produces both doors and locks, as their door locks are of good quality. All doors come with Over B locks. Those with substantial resources might consider Pan Pan's Jing Jing (Pan Pan has B-grade locks, be aware), which is also Over B grade, although it's quite expensive. The door itself is still excellent.

Can a security door really prevent theft?
As an entry door, security must be the top priority, with aesthetics coming second. Anti-theft measures have evolved from the primitive act of holding the door handle with a single stick to the multiple locking points we have today, significantly enhancing safety performance. However, we must understand that there is no door that cannot be opened; the anti-theft coefficient merely refers to extending the time it takes to breach the door.

When selecting anti-theft doors, developers must adhere to national standards, but price is also a significant factor. Merchants always prioritize making a profit, and typically, the lower the price, the better, as long as it meets national requirements. I once saw a case where the matching anti-theft door lock was not smooth; after the maintenance personnel arrived, they held the top of the door, grabbed the middle lock area, and with a strong pull, it was fixed. After they left, I gave the door handle a tug to test it, and I was genuinely worried it might come off.
