How to Choose a Security Door

Installed anti-theft door at home but often stolen how the security door can really play a security role, the experts may wish to listen to the presentation.

Price Quality

As the saying goes, the price of a one freight, of course, do not rule out the possibility of business to make money, but as long as the quality of the hardware, this is a grain of truth. At present, there are two to three hundred dollars to sell anti-theft doors, to let an expert accounts, a qualified anti-theft lock in the price of hundred dollars more than the current anti-theft door manufacturer concentrated in the area in Zhejiang, Shaanxi Province to Zhejiang The freight will take about 40 yuan, plus installation costs 20 yuan, the city transport costs around 20 yuan, the door itself is not the cost of its additional costs have nearly 200 yuan, so the quality of such a door can be imagined. Industry experts Yucai Yang, qualified the security door of their normal price should not be less than 800 yuan bottom line.

There are also anti-theft door "ID card"

Qualified security door should have three "card." First, the local public security departments for the record books, and we must pay attention to whether the life of. Secondly, the product testing report. At present, the Ministry of Public Security and General Administration of Quality Supervision authorized testing agencies have seven, respectively, in Sichuan, Beijing, Shaanxi, Guangzhou, Wuhan, Shanghai, Shenyang, and is only valid for two years, expired null and void. Third, the lock detection separate report should be dedicated to anti-theft locks, is valid for two years, expired null and void.

From the outside to watch quality

In addition, when consumers can buy through their own testing to determine the quality of security door. First of all, due to the plate, the larger framework, such as weight, the weight of anti-theft doors in more than 60 kg. Second, turn off the sound when they should be very boring at the same time due to the thick steel plate is not easily deformed, so the gap after the installation of a more even, no small deformation of the phenomenon. Once again, tapping his hand on the surface of the door, issued a dull voice, its steel skeleton is not a filler, the steel skeleton of a normal voice should be clear. Finally, although the countries do not have clear anti-theft door without handrails, but the experiment proved that the handrails will be more and more of a force, it reduces the abnormal opening of the difficulty of the anti-theft outside the table so it is better not to add a good arm.

The more complex the key, the better

The key to the complexity of a direct impact on the structure of the anti-theft lock, the key to cross than the flat-key lock of the internal structure of much more complex, cross-lock four directions are billiards, and the lock plate as long as both sides have to billiards, in the same Under the best conditions for cross-lock option. Also the longer the key, the key point of convex-concave surface of the more complex the lock that the internal structure of the more complex the abnormal opening, the higher the degree of difficulty.
