  • Detail

In the hot season of decoration every year, many citizens often consider installing a security door on their new building after they get it, so as to increase the security of their new home. However, how to choose a safe and suitable security door? The reporter recently interviewed Dong Yan, the head of Foshan Panpan anti-theft door sales center, and asked him to talk about the little knowledge of choosing anti-theft doors

Dong Yan told reporters that when choosing anti-theft doors, we should first consider choosing enterprises and distribution stores with relatively large scale, good reputation and standardized sales services, because large-scale anti-theft door factories have fast lock updates, good after-sales services, and usually have the service of replacing old ones with new ones. In this way, the behavior of illegal elements imitating the unlock key can not keep up with the update speed of the lock to ensure safety. At the same time, the lock used on the door must be a real anti-theft lock, because the door lock is the core of the anti-theft door, which is far more important than style and price. Secondly, the door lock must have an anti drilling device, and the structure of the lock is anti prying. It is best to choose B-level anti-theft door lock with high protection level. In addition, attention should also be paid to product identification, such as the marking of anti-theft safety doors “ FAM”、 Enterprise name, trademark, specification and model, executive standard, etc

Dong Yan said that the level of anti-theft lock is divided into three levels: A, B and C. Class a anti-theft lock is qualified if its destructive opening time is not less than 15 minutes and its technical opening time is not less than 1 minute. The destructive opening time of class B anti-theft lock is 30 minutes, and the anti technical opening time is not less than 5 minutes. The destructive opening time of level C anti-theft lock is 45 minutes, and the anti technical opening time is not less than 10 minutes& ldquo; The anti-theft safety performance of anti-theft doors with different anti-theft levels is different. For example, the anti damage time: Class A anti-theft door shall not be less than 30 minutes, class B shall not be less than 15 minutes, class C shall not be less than 10 minutes, and class D shall not be less than 6 minutes; The number of locking points between the door frame and the door leaf, class A, class B, class C and class D anti-theft doors should be no less than 12, 10, 8 and 6 respectively; The thickness of steel plates of the door frame of Grade A, B, C and D should be 2mm, 2mm, 1.8mm and 1.5mm respectively. Consumers can choose the anti-theft door they want according to their needs& rdquo;

finally, Dong Yan said that the weight of the door body should be checked, generally more than 40kg, and the internal structure of the door body can be checked by removing the cat's eye, door bell box or lock handle. The thickness of the steel plate of the door body should be more than 0.5mm, and there are several reinforced steel frames inside, so that the front and rear panels of the door body are organically connected together to enhance the overall strength of the door body. The door is generally filled with polyurethane or honeycomb paper, which has the functions of heat preservation and sound insulation
