Buy anti-theft door Do not just look at the appearance with the steel plate key to see the lock

A few days ago, when interviewed by reporters on the anti-theft door market, many people did not understand what a good security door was. They often only paid attention to the appearance of the door and the steel plate when they purchased the security door, but they ignored the 'heart' of the security door. --- Locks, and most dealers did not mention locks to reporters when they were selling their own products. They simply emphasized how thick the steel plate was and how the price was discounted. They did not remind customers to pay attention to the locks. If the locks are not closed, the customer may buy a home-made anti-theft door.

The dealer is vague, most of the people do not ask for a lock

In some shops selling anti-theft doors, the reporter found that many consumers choose the styles and different styles of anti-theft doors, they usually turn the door handle, knock on the steel plate, and some will ask the thickness of the steel plate. The installation situation, but ignored the core of the security door - lock. A Li Xing consumer told reporters that he believes that steel plates with thick, luxurious appearance are good. Miss Liu, the citizen, said that the security doors and entrance doors of the new home were all purchased by the developers, and they did not know how safe the door was.

Because consumers do not pay much attention to the safety performance of the door locks, many dealers do not explain locks when selling security doors, let alone introduce some professional knowledge about locks. In some stores, many dealers see consumers come to the door, first introduced the style of the security door, work, and rarely mentioned the security door locks and their level. When reporters asked about the security performance of security doors, and whether there is a security technology product for production license issued by the public security department, some dealers have said that their security doors have multiple lock points such as 'world locks' and lock edges. , Excellent quality, will certainly not be easily opened, and some come up with the manufacturer's ISO series of certification, some said that security doors have 10 million quality insurance. When the reporter asked whether the security level of the locks was A or B, some dealers answered that the locks sold by the store were AB locks. When the decoration was completed, the workers used the A keys to open the door. After the renovation, As long as the owner inserts the B key into the lock hole, the A key is scrapped.

The key to anti-theft is the lock

An industry source told reporters that the number of anti-theft doors currently sold on the Huizhou market is as many as several dozen, as large as some domestic brands, and as small as some local brands, prices range from 700 yuan to several thousand dollars, but some anti-theft locks No security at all. According to reports, the two basic components of anti-theft door security are the door body and the anti-theft lock. 'The door lock is an important part of the security door, if the quality of the door lock but off, even the best security door can not fully play the anti-theft function. 'A well-known brand security door dealer told reporters. According to the “GA/T73-94 Mechanical Anti-theft Lock” promulgated by the Ministry of Public Security, mechanical anti-theft locks are classified into ordinary protection levels and high protection levels, which are represented by Class A and Class B respectively. The technical protection of Class A locks is not less than 1 minute and the destructive resistance is not less than 15 minutes; the technical protection of Class B locks is not less than 5 minutes and the destructive resistance is not less than 30 minutes. However, the vast majority of anti-theft locks on the market today are locks of ordinary protection levels. Some businesses say that their security doors have too many lock points and no one can open them. In fact, they are confusing the concept of lock points and lock cylinders. The lock points are the points where the door body and the wall body are connected together, and they have anti-smashing function. The lock core is the core of the anti-theft lock. All anti-theft locks have only one lock core. As long as the lock cylinder is open, all the lock points are opened.

Pay attention to the "test report"

How can we buy a good security door? The person in the industry reminded the public that they should choose a reputable big brand as much as possible when buying anti-theft doors. They must ask the dealer for an “inspection report”, carefully review the inspection conclusions, and distinguish the distribution of the anti-theft door installed by the dealer. Locks or B-level locks and pay attention to the following things:

Certificate: The real security door must be qualified by the statutory testing agency according to the standard, and there is a production security permit issued by the security technical protection department of the provincial public security bureau (bureau).

Locks: The core part. Qualified security doors generally use three-dimensional locks. Not only are the doors locked, but the upper and lower crossbars can be inserted and locked to fix the door. Inferior products generally do not have a three-point locking or optional three-point locking structure, and do not have anti-theft function or frequent failure.

Process quality: Special attention should be paid to checking for any welding defects such as open, unwelded, missing welds, slag inclusions, etc.
