In the blink of an eye, the decoration season, many people are very entangled in the choice of security doors, facing the various products on the market, to avoid entering the pit, Xiaobian now to give you a few tricks.
1. How to distinguish between true and false security doors?
The anti-theft security door is produced according to national standards. The steel door, metal door and entrance door are produced according to the enterprise standard. Therefore, seeing the standard has become the first step for consumers to identify the security door. Open the door and see if there is a sign for the anti-theft security door in the upper corner of the inner door. Pay attention to the "anti-theft security door". If there is no such sign or the metal door, steel door or entrance door, it is not a security door.

2, understand the anti-theft performance of the security door
The lock core level is divided into three levels: A grade, B grade, super grade B;
1 The internal structure of the A-class lock cylinder is very simple, limited to the change of the marble, and the marble groove is small and shallow. The anti-technical opening time is extremely high within 1 minute.
The 2B lock key is a flat key with a double row of marble slots. The difference with the A lock is that the key face has a row of curved and irregular lines. The main types of lock cylinders are 3 types, computer double-row lock core, double-row crescent lock core, double-sided vane lock core. The anti-technical opening time is 5 minutes, and the mutual opening rate is high.
3 super B-class anti-theft lock to prevent destructive opening time of not less than 30 minutes, the key shape is single-sided blade inner milling slot or outer milling slot key, the lock core type is side cylinder lock core; can not be opened by the Ministry of Public Security for 270 minutes The regional mutual opening rate is zero (one in six million). The structure of the marble is locked by the double row of blades and the V-shaped side column; if the lock cylinder is opened by a strong twisting tool, the internal core of the lock cylinder is broken, and the self-explosion is locked, resulting in failure to open.
3. Understand the thickness of the board
The national standard requires that the door must be stamped. If the door is not stamped, it will not meet the requirements of the national standard. Obviously, it is not a security door.
The grade marks are divided into four types: A, B, C and D. The small series will give you a detailed introduction:
Grade A security door steel plate thickness
Grade A: the thickness of the door frame steel plate is 2.0mm, the thickness of the door leaf plate is 1.0mm, and the locking position of the door frame is not less than 12;
Grade B: The thickness of the door frame steel plate is 2.0mm, the thickness of the door leaf plate is 1.0mm, and the locking position of the door frame is not less than 10;
Grade C: the thickness of the door frame steel plate is 1.8mm, the thickness of the door leaf plate is 0.8mm, and the locking position of the door frame is not less than 8;
Ding grade: the thickness of the door frame steel plate is 1.5mm, the front plate steel plate thickness is 0.8mm, the rear plate is 0.6mm, and the door frame locking point is not less than 6;
4, understand the security door production process
Process quality pay attention to whether there are defects such as open welding, non-welding, and leakage welding. See if all the joints such as the door leaf and the door frame are dense, whether the gap is uniform, whether the opening is flexible, whether the paint plating is uniform and firm, and smooth.

5, matters needing attention
After the security door is installed, check whether the normal switch of the security door is smooth. The key is 2 decoration keys, 5 or 6 master keys. After the master key is rotated 360 degrees, the decoration key is automatically invalidated. Check whether the lock is consistent with the data. After the warranty documents are collected, they are used for maintenance.
Here, Xiao Bian I wish you all a safe and secure door to your door!
