At present, the purchase of homes in China has become a "habit", and the installation of security doors has become one of the supporting services for consumers to purchase houses. As early as a few years ago, it was reported that the security door key provided by the property could open several doors, and even was written as a material in the sketch, but after many years, its problems are still common. Is the universal key open to several people, but also become the "hidden rules" of the door industry locks? The anti-theft door is called "anti-theft security door". Because of its strong security, it is durable, flexible, and beautiful. It is widely used in civil buildings and houses, high-rise buildings and confidential rooms, and finance departments. On April 1st, 2008, the new national standard also divided the anti-theft security level of the security door into “Aâ€, “Bâ€, “C†and “Dingâ€. The anti-theft security features of different anti-theft levels are different. The anti-theft door anti-destruction time should not be less than 6 minutes to ensure that it is "safe", and A is the highest level, and thus decremented accordingly. At present, there are many types of security doors on the market. According to the GB25-92 "General Technical Conditions for Security Doors" issued by the Ministry of Public Security, the security doors can be divided into three types: fence-type security doors, physical doors and composite doors. The security door is mainly divided into steel, steel-wood structure, stainless steel, aluminum alloy and copper. They are characterized by quality and performance, and the natural price is not the same. In order to save costs, some door companies have reduced the cost of locks and strived to exchange large quantities of orders at low prices. However, in order to reduce the total cost of home sales, real estate enterprises do not look at the goods. It is understood that the security door is qualified, the lock is the most important, and the quality of the lock is subject to the national standard, and the lock is not followed by a test. Such as: Class A security door must not be less than 30 minutes, Class B is not less than 15 minutes, Class C is not less than 10 minutes, D is not less than 6 minutes; Locking points between door frame and door leaf, A, B, The safety gates of C and D grades shall be no less than 12, 10, 8 and 6 respectively; and the thickness of steel plates of door frames shall be 2mm, 2mm, 1.8mm and 1.5mm respectively. Wait. These are often overlooked by the owners. Some of the owners have requested inspections, including unsuccessful results. Most of them have taken the door to change their jobs. The author here wants to remind the lock company that when the owner is infringed by rights, the first thing to pay attention to is the lock brand. If lock companies want to ignore the terminal demand and the decisive influence of the terminal, I am afraid that it is a myth that the company wants to be bigger and stronger.
