The reporter investigates the security door market lock and shakes it with one touch

Recently, the Shanghai Municipal Industry and Commerce Bureau has tested the security doors of 11 real estates that have not yet been delivered in the city and the security doors sold by a building materials supermarket. The results show that the pass rate is only 1.5%. This week, the reporter investigated the Beijing security door market.

The reporter found

Supermarket anti-theft door lock is actually loose

The reporter found in the interview that the quality problems of security doors sold in this city are also worrying.

At the sales office of the anti-theft door of the Oriental Home Garden Supermarket in Lize Bridge, a security door of 980 yuan was sold in Beijing. The reporter was surprised to find that the inside lock was very loose, and the reporter could gently shake it with his hand. When the reporter asked whether there was a problem with the quality of the door, the shopping guide next to the reporter did not answer the reporter's question positively, but took the reporter to another anti-theft door without mentioning the door the reporter consulted.

What kind of door lock is professional

In an anti-theft store in Dongfang Huimei Home Building Materials City, the salesperson told reporters that there are few B-level anti-theft doors in the market, and the most commonly used are A-level. But if the consumer wants to make a B-level lock, a lock needs more than 1,000 yuan, plus another 100 yuan, the result is a B-level lock.

The reporter saw a "patent anti-pry" anti-theft door in another anti-theft store, which was more expensive than the general anti-theft door. According to the sales staff, this door has two anti-theft bolts on the side and two corresponding slots on the side of the door frame. When closing the door, the bolt is directly inserted into the slot to play a fixed role. If you pry the lock outside It is difficult to pry open the door, because these two anti-theft bolts cannot pry open at all.

The reporter interviewed several consumers on the spot. Most people said that they did not know what kind of anti-theft door is safe, and they did not understand the technical requirements of professional door locks.

Expert analysis

Thick steel plate for door frame

The reporter learned that, according to the relevant standards, the thickness of the steel plate used in the manufacture of door frames for anti-theft security doors should not be less than 2 mm. In actual testing, the thickness of some anti-theft security door frame steel plates is only 1.2 mm, "such a weak door frame is not only easily deformed, but also greatly reduces the service life of anti-theft security doors."

There are many anti-theft lock points

Experts suggest that you should pay attention to the anti-theft function of the lock when purchasing. At present, the common anti-theft lock grades on the market are A grade and B grade are rare, but the anti-theft function is higher; and the best anti-theft performance is C grade. Among them, Class A is suitable for family use. Experts also said that consumers should also focus on how many anti-theft locks there are. In the same situation, the more locking points, the better the anti-theft performance of the lock.

Fireproof rock wool selected as internal filler

According to industry insiders, at present, the internal filling of anti-theft doors is of the best quality with fireproof rock wool. The anti-theft door filled with fireproof rock wool can integrate the door leaf with the inner cavity, and the anti-theft performance is good. Moreover, it also has thermal insulation and sound insulation performance. When purchasing an anti-theft door, be sure to open the cat's eye to see, so that the internal structure can be seen.

Consumer advice

At the time of purchase, the request will be written into the contract

Industry insiders remind consumers that because consumers do not have the conditions to identify the quality of anti-theft doors, they must sign a contract when buying.

When purchasing an anti-theft door, you should first check the quality inspection report of the anti-theft door, and check whether the production batch number and model specifications on the inspection report are the same as the actual product. In addition, during the ordering process, the words "anti-theft door" should be marked on the invoice to prevent unscrupulous operators from selling "steel doors" and "armored doors" as anti-theft doors. It is understood that during the random inspection of anti-theft doors in Shanghai, there were cases of merchants posing as anti-theft doors with ordinary steel doors.
