Security door procurement
1, depending on the size and opening direction of the door.
There are generally four specifications for household standard doors, which are represented by four digits composed of the width and height of building openings. For example, the width of the doorway is 1 m and the height is 2. 1 m, and its specification is called 102 1. Commonly used specifications are 0920,0921,102 1. The opening direction of the door is divided into internal opening and external opening, and it is also divided into left opening and right opening. Users can choose the opening direction of the door according to the convenient opening direction.
2. Pay attention to the surface quality and safety of the security door.
The thickness of the steel plate used for the steel security door frame should not be less than 2mm, and the thickness of the steel plate generally used for the front and rear panels of the door leaf is between 0.8-1mm.. The national standard requires that the door must have a steel seal, and the grade steel seal of the security door is generally on the hinge side of the inner door. If the door you see is not stamped, it does not meet the requirements of the national standard and does not belong to the security door.
3. Pay attention to the security of the security door hardware.
The anti-theft performance of the security door is mainly the performance of the key and lock, so you must check the performance report of the key and lock when choosing the security door. The lock detection report directly indicates the time of anti-technology opening experiment, which is what we usually call a few minutes to open the door lock. If the merchant can't get the lock core test report, it means that the anti-technology opening test time of this security door is unknown.
4. Choose professional brand security door products.
Brand is a symbol of product quality and service. Brand mainly refers to product brand and dealer brand. When buying security doors in the market, it is best to buy them in a regular large-scale home building materials city. Attention should also be paid to the "FAM" sign, enterprise name, implementation standards and other contents of the security door when purchasing, so that the door that meets the standards can be both safe and reliable. When customizing or buying security doors, you should buy qualified products from manufacturers who have obtained the production license registration certificate issued by the Public Security Bureau.
Matters needing attention in purchasing security doors
The results of quality supervision and spot check of security door products announced by AQSIQ show that the products produced by large and medium-sized enterprises are of good quality, but there are still 6.5% products of small enterprises that are not anti-theft. A good "security door" is the protector of life and property. Security doors have horizontal opening, push-pull type, folding type, fence type and other structural forms, and the family is mainly horizontal opening. Focus on the following four points when buying:
Look at the filler and steel plate thickness.
You can have a look at the security door when you install it. Usually you can see what's inside by unscrewing the cat's eye from the door. If some cat's eyes are already installed and can't be unscrewed, you can look at them when you lock the door. Consumers can knock on the security door with their hands, and the sound is firm, indicating that the steel plate is thick enough and the filler is solid. If the sound sounds "poop-poop", it means that the steel plate is not thick enough. According to the national regulations, the thickness of the steel plate of the security door should be above 1mm, but the thickness of the security door made by some small workshops can't be reached at all, so something should be used to open it. In addition, it is to use hot-rolled plate instead of cold-rolled plate. Hot-rolled plate has poor toughness and surface smoothness, and the price is lower, while cold-rolled plate has good ductility and toughness, but the price is higher, so some manufacturers switch to hot-rolled plate in order to save costs. Moreover, the surface of the steel plate of the security door should be galvanized or phosphatized before painting, so that the steel plate can be painted directly and is not easy to be corroded.
Locking more is just a cover.
Lock is an important part of security door. Many sellers of security doors say that they have many security doors when they sell them, but this is actually just a cover to attract customers. The really good locks are not the more locks, the better. There is no essential difference between four locks and 10 or 20 locks. No matter how many lock points there are, the center is on the lock core. As long as the lock core is broken, no matter how many lock points are used. Of course, if only one lock cylinder is wrong, generally four lock cylinders are enough.
Buy in the regular market
There are many security doors on the street now, and it is undeniable that some of them are well-known brands, but if consumers don't recognize the authenticity, it will be miserable. Security doors are different from ordinary doors. In order to prevent being fooled, it is best to buy it in the formal decoration materials market. Because if you want to sell security doors in the formal decoration materials market, you must obtain the approval of the special police branch of the Public Security Bureau, and the decoration materials market generally requires the settled merchants to provide relevant certificates for selling security doors. Generally, well-known security doors have sales points or specialty stores in the decorative materials market.
Look at the production and sales license
Consumers can view the relevant certificates of products. In addition to this production license, the manufacturer should also have the corresponding technical inspection certificate. Such as fire inspection report, seal inspection report, etc. , so that you can have a general understanding of the technical performance of the product.
In addition, we should also pay attention to whether the date of purchase, the address of the point of sale and the contact telephone number indicated on the warranty card issued when purchasing the security door are consistent with the actual situation, so as to contact when necessary and also serve as the basis for verifying the warranty period, so please be sure to ask for the warranty card, read it carefully and fill it out, and keep it properly.
