How to choose an anti theft door, how to choose an anti theft door?

Many anti-theft door consumers said that the anti-theft door market is chaotic, they are difficult to choose, today, the door to the door network ** anti-theft door purchase points! In recent years, the name of the anti-theft door market product name is confused, the standard is not uniform, in order to escape the inspection of the quality inspection department, the name of the anti-theft door becomes a steel door, a metal door, a standard door, etc., in addition to the confusion of the door name, the quality of the anti-theft door is uneven. The thickness of the steel plate of some anti-theft doors is not up to standard, and it can be opened in tens of seconds; There are also some anti-theft doors that are not anti-theft locks at all, but ordinary locks; The most serious problem is that some security doors have neither a factory name nor a factory address, and they are labeled with other products after they are done, and then sold at an ultra-low price.

According to reports, the reason for such a situation is that the original standard of the anti-theft door is lagging behind. In this regard, the relevant departments have formulated and introduced new standards for security doors. The new standard has made mandatory provisions on the terms related to the security of the security of the security of the security of the security of the security door, and consumers can choose more safe and reliable security door products according to the new standard.

There are three ways for ordinary consumers to judge the quality of security doors. The first option is to look at the permanent marker. According to the new standard, each security door must have a permanent mark (anti-theft security level):

It is composed of Chinese codes (A, B, C, D) and a flat circle, the Chinese code is located in the plane circle, permanently fixed in the upper corner of the inner hinge in the form of Song intaglio print, 1600 mm above the ground height 100 mm. The second method is to observe the locking points between the door frame and the door leaf. The so-called locking point is the connection point connecting the door frame and the door leaf, according to the anti-theft security level, the locking points of A, B, C, D four levels should be not less than 12, 10, 8 and 6 respectively.

The third method is to judge from the **, the Grade A security door is about 1800 yuan, and the Grade D security door is about 1000 yuan. A penny for a penny, two or three hundred yuan of security door quality is of course difficult to guarantee. The new standard divides the security level of the security door into four levels: A, B, C, D, of which Class A is the highest level, as a consumer, these four levels of security doors can be selected.

If consumers are not at ease with the manufacturer of the anti-theft door, they can first go to the Technical Defense Office of the Public Security Bureau to check whether there is a registration of the manufacturer. The above is the key point of the purchase of anti-theft doors, door-to-door network.

There are too many doors now, so there is a lot of garbage. Generally, it is good to customize it yourself, and the door frame of the façade should be above the best to be customized by the large factory, and the details can be customized by yourself.

The purchase of anti-theft doors should be based on the following points:

1. Doorman.

Be careful to buy steel doors, steel doors and security doors look very similar. The anti-theft door should meet the requirements of the GB national standard is the real anti-theft door, when choosing the anti-theft door, you must see whether there is a grade mark on the inside of the door. All security doors must be stamped on the side near the hinge, about a meter high from the bottom of the door.

2. Look at the door lock.

The most critical and core of the anti-theft door is the door lock, and the state divides the lock cylinder of the door lock into three types according to the security: Class A, Class B and Class C. You must buy a C-grade lock cylinder, not C-class, it is recommended to upgrade and replace it with C-class. Like the current popular smart lock, it is recommended to choose a semiconductor capacitive fingerprint head, and the living fingerprint can be identified and unlocked.

3. Look at the internal filler.

The internal filling of the door body must be paid attention to, and when buying, you must ask what kind of filling is inside. The fillers mainly include honeycomb paper, fireproof rock wool, polyurethane foam, aviation aluminum foil, etc., it is recommended to choose the best aviation aluminum foil, fire prevention, sound insulation, and warmth are good, honeycomb paper should not be chosen.

4. Add cat's eye device and anti-pry sleeve.

If you want to improve the safety level, adding a cat's eye device and an anti-pry sleeve will improve the safety factor.

First, look at the material.

The lock materials on the market are basically divided into stainless steel, copper and zinc alloys. Stainless steel has high strength, strong corrosion resistance and no discoloration, which is the best lock-making material; Copper is relatively versatile, with superior mechanical properties and high quality; High-quality zinc alloy is strong, wear-resistant, corrosion-resistant, and easy to form, and is mostly used for mid-range locks.

Second, look at the surface treatment.

Surface treatment is roughly divided into three types: electroplating, spraying and coloring, through surface treatment to form a dense protective film on the surface of the product, which plays a role in anti-corrosion and anti-rust, making the product more beautiful and durable. At the same time, it is also a standard to measure the quality of the product, the most advanced locks, mostly using electroplating treatment, the plating layer is delicate and smooth, uniform and moderate, the color is bright, no bubbles, rust and signs of oxidation.

Third, look at the implementation standards.

Foreign countries have very strict standards for hardware locks, so the quality of imported products is relatively high. At present, the Ministry of Light Industry has learned from some foreign standards to revise the original implementation of GB into the current higher requirements of QB, there are brand manufacturers have been implementing QB standards, small manufacturers are still implementing the original GB standards, in the purchase must be clear about the implementation of the product standards.

However, in order to reduce costs, some companies will reduce the thickness of the steel plate, and the steel plate is too thin at this time to have a certain effect. Therefore, when choosing an anti-theft door, you can measure its thickness, if you reach this thickness, you can buy it, if it does not reach the best, do not buy.

2.And when checking the steel plate, press the steel plate inside the door panel. If the steel plate is pressed down, it means that the quality of the door is relatively poor and it cannot be purchased.

The security door must be purchased in the regular building materials market or a large shopping mall, because the quality of such an anti-theft door will be guaranteed, and there are people to maintain it after sale. If you buy it at a stall, it won't work for a certain purpose, and you may buy an inferior product.

3.And the anti-theft performance of the anti-theft door is also relatively related to the lock and key. When choosing an automoatic door, be sure to look at the performance report of the key and the lock, because the lock inspection report will show how long it takes to open the lock.

If the merchant does not have a test report of the lock and lock cylinder, it means that the quality of the anti-theft door does not meet a certain standard, so it cannot be purchased.

4.When choosing an anti-theft door, you can choose a suitable anti-theft door according to the decoration style of your home, and you can choose from the color and process of the anti-theft door, so that the installed anti-theft door and the decoration of the home are matched with each other.

1. When choosing an anti-theft door, the most important thing is to check the size of the door opening on the decoration drawing, so as to avoid buying an oversized or oversized anti-theft door, and the opening direction of different decoration doors is also different, which also needs to be paid attention to to avoid embarrassment caused by opening the door.

2. When choosing an anti-theft door, some friends will choose to customize, and the customized anti-theft doors are relatively high-end, but it is also necessary to pay attention to the fact that some small manufacturers will also be mixed in it.

3. When choosing an anti-theft door, you must remember to shop around, no matter what you buy, this method is relatively good, even if it is the same style and the same brand of anti-theft door, in different stores due to various discount activities, etc., ** will be slightly different.

4. When choosing an anti-theft door, it is more important to check the overall process quality of the anti-theft door, because after all, the anti-theft door is used to use, if the anti-theft door itself has welding defects, or the density is not enough, it will definitely affect the use of the effect experience.

5. When selecting the anti-theft door, if conditions permit, you can weigh the overall weight of the anti-theft door, because the important requirements for the anti-theft door are stipulated by the country, and the weight of the anti-theft door produced by the regular manufacturer can not be less than 40kg.

6. When choosing an anti-theft door, you should still pay attention to the brand, the brand is more important for the quality of the product and the after-sales service in the later stage, the quality of the anti-theft door of the big brand must not worry, and the corresponding after-sales service is also relatively perfect.

1.Choose a regular manufacturer and be sure to have a certificate of conformity.

The anti-theft door produced by the regular manufacturer will have the testing certificate issued by the statutory authority, and has the production certificate of the security technology protection product issued by the provincial public security department (bureau) installation technical prevention department where the manufacturer is located.

2.When purchasing, you should also check the anti-theft rating of the security door.

According to the thickness of the door panel and door frame, the anti-theft door is divided into four grades: A, B, C, and D, among them, Grade A is the best and the most expensive. Security door manufacturers with formal production qualifications will put the anti-theft level on the door frame.

3.When purchasing, you should also pay attention to check the anti-theft door lock.

The qualified anti-theft door adopts a high-quality professional anti-theft lock, and the surface of the lock should be protected by a steel plate with a thickness of more than 3mm to avoid damage to the door lock due to external forces. Door locks are also divided into three grades: A, B and super B, among which, super B is the best and the most strong and firm.

4.The weight and thickness of the security door are also one of the indicators for choosing an security door.

The thickness of the steel plate of the anti-theft door needs to be more than 2mm, the thickness of the door body should be more than 20mm, and the weight needs to be more than 40kg.

5.The production and installation process of the security door is also a place that needs to be investigated and paid attention to.

When we choose an anti-theft door, we should pay attention to whether there are flaws on the surface of the anti-theft door, whether there are welding defects, such as open welding, missing welding, etc., and also check whether the mating of the door frame and the fan is dense, whether the surrounding clearance is consistent, and whether there is noise when the door is opened and closed.

To distinguish whether it is an anti-theft door, you need to look at three marks: 1. Qualified certificates. The real anti-theft door must be tested by the statutory testing agency according to the standard, and there is a safety technology protection product license issued by the provincial public security department (bureau) where the manufacturer is located.

Therefore, when consumers make a purchase, they should first ask the seller to show the test report of the relevant department. 2. "FAM" nameplate. The current "General Technical Conditions for Anti-theft Security Doors" stipulates that anti-theft doors must have a "FAM" nameplate, generally in the upper right corner of the door, in addition to the name of the enterprise, implementation standards and other content.

3. Security level marking. According to the national standards implemented on April 1, 2008, according to the anti-vandal time, steel plate thickness, locking points and other four types of indicators, the anti-theft door is divided into A, B, C, D four security levels (code "J, Y, B, D"), of which Class A anti-theft performance is the highest, Class D is the lowest.

Now basically every household will install an anti-theft door for the sake of safety, and the following pchouse will talk to you about how to choose an anti-theft door.

Differential. First, the seller is required to show the "Test Certificate" of the relevant departments to check whether it meets the technical requirements of the national compulsory standard GB17565-1998.

Second, remove the peephole, doorbell box or lock handle and check the internal structure of the door. There should be several reinforcing steel bars inside the door to organically connect the front and rear panels of the door body. It is best to have asbestos and other materials with fireproof, thermal insulation and sound insulation functions as filling.

Third, check whether the lock adopts a special lock for anti-theft that has been tested and qualified by the public security department, and whether there is a reinforced steel plate for protection at the lock installation site.

Fourth, check the process quality of the product, whether there are welding defects, whether the fit between the door leaf and the door frame is dense, etc.

Fifth, check the weight of the security door, the weight of the regular security door is not less than 40 kg.

Identification tips. At present, the security door products are uneven, some businesses are like grocery stores, operating a variety of security doors, how should consumers identify, buy qualified security doors? To summarize the following:

1. Grade standard: The security level of the anti-theft door can be divided into Class A, Class B, Class C and Class D, among which Class A has the highest anti-theft performance, followed by Class B and Class C, and Class D is the lowest. Most of the doors we see in the building materials market are Class C and Class D security doors, which are more suitable for general family use.

2. Check the steel plate: the state stipulates that the thickness of the steel plate of the anti-theft door should reach 1 mm, but some enterprises in order to reduce costs, some only use millimeters of steel plate, and the plate is thin and loses the significance of anti-theft. According to the anti-theft door business, when the consumer inspects the steel plate, you can press the steel plate in the door leaf, if the steel plate is pressed, indicating that the quality of the anti-theft door is not up to par.

3. Check the step: The qualified anti-theft door step is made of stainless steel, but some small workshops use stainless iron in order to reduce costs. When the author visited Nanchang Xinduo anti-theft door, the boss introduced a trick for identification, put the magnet on the lower step, if the magnet is sucked and it is difficult to take it away, indicating that the stepping material is unqualified.

4. Good locks not only have many lock points: the locks are qualified anti-theft doors generally use three-way locks, not only the door locks are locked, but the upper and lower crossbars can be inserted and locked to fix the door. Often some businesses use more locks to attract consumers, in fact, a good lock is not the more lock points the better, the lock cylinder is not anti-theft, no matter how many lock points are useless.
