Anonymous users2024-01-221. Look at the anti-theft mark. If you buy a brand of security doors, then when we buy, you can carefully observe whether it has the corresponding brand logo, many "fake and shoddy" security doors do not have these logos. When we pick in the store, we can also ask the merchant to open the door and see if there is a relevant grade mark on the left side of the door frame.
The state has a unified definition of the security level of the anti-theft door, and there are four levels of "A, B, C, D", and Class A is the best, and so on. However, there are quite few Class A security door products on the market at present.
2. Look at the thickness of the steel plate. Relatively speaking, its anti-theft and the thickness of its steel plate are directly related, if the thickness of the steel plate is thicker, it means that its quality is better, and the anti-theft performance is better. The country's minimum standard for the thickness of the steel plate of the anti-theft door is the door frame.
If you want to judge the thickness of the steel plate, the easiest way is to "push, knock": knock on the door, if the sound is thick and dull, it means that the quality is better, if the sound is crisper and the search is only hollow, it means that the quality is poor.
3. Look at the locks. Door lock is a key point to judge its anti-theft, if you want to distinguish the quality of the door lock, we can understand through its grade. Generally speaking, anti-theft locks are divided into A, B, super B levels, the more complex the structure of the lock, the more complex the key pattern, it means that the longer the lock is opened, the better the anti-theft Shipei.
If you don't know how to pick a security door, then I hope the above will help you.
