How to choose an security door? How to choose an anti theft door?

In addition to observing the appearance such as no bubbles on the surface of the paint layer and uniform color, if the level is the same, the larger the weight, the more lock points, the denser the steel skeleton, and the more lock protection, the quality of the anti-theft door is relatively good. Since it is difficult to see the skeleton of the security door, the owner can refer to the product section (section) provided by the dealer and judge it from the weight. Generally speaking, the greater the weight and the denser the steel skeleton inside, the stronger and safer the door.

Certificate of conformity. 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.

Security level. According to the relevant standards, the security level of the anti-theft door can be divided into Class A, Class B and Class C, of which Class C has the highest anti-theft performance, Class B is second, Class A is the lowest, most of the anti-theft doors we see in the building materials market are Class A security doors, which are generally suitable for general family use.

The locks are secure. Qualified anti-theft doors generally use three-way locks or five-way locks, not only the door lock locks, but also the upper and lower crossbars can be inserted and locked to fix the door. Most doors also have rubber seals embedded in the door frame, which makes a screeching metal crash sound when the door is closed.

Brand Assurance. Brand is a sign of product quality and service. Brand mainly refers to the product brand and dealer brand, when buying anti-theft doors in the market, it is best to buy in the regular large-scale home building materials city.

When purchasing, you should also pay attention to the "FAM" sign of the security door, the name of the enterprise, the implementation of the standard, etc., and the door that meets the standard can be both safe and reliable.

Therefore, when consumers buy anti-theft doors, they should not blindly covet the number of lock points. Generally speaking, it is sufficient for a lock to have four locking points. In the face of many brands of security doors on the market, relevant people remind everyone that when buying security doors, you must first know what is the filling in the security door you choose?

After you decide to buy, it is best to sign a contract with the merchant, in which it is clear what kind of filling is used, so that if you find that the filling is not right when installing the security door, you can use the contract as the basis to discuss with the merchant. Secondly, when you buy an anti-theft door, it is particularly important to see whether the seller has a production and sales license issued by the Public Security Bureau. If the manufacturer does not have this production license, you should never buy it lightly.

In addition to this, some relevant supporting documents of the product are also essential. Like the corresponding technical inspection certificate, including leak test report, fire inspection report and insurance certificate, etc.

Of course, the anti-theft door must choose a big brand, and it is necessary to choose, the counter **, so as to ensure the quality, and the after-sales service is also in place.

These two points need to be understood before the purchase of security doors.

1. The size of the door opening of the anti-theft door.

The anti-theft door is installed with its own door opening size requirements, generally there are two common sizes: 2050mm 960mm, 2050mm 860mm, if it is an old house renovation, the door opening of the anti-theft door is generally relatively small, for the current common door, the height of 2050mm 1180mm will generally be used.

2. The opening direction of the anti-theft door.

Most of the security doors are opened outward, and there are internal openings, because the inner opening occupies the indoor space, and the entrance is not easy to do, so most of them are opened outward.

After understanding the basics of security doors, let's take a look at how to choose security doors.

1. Look at the level of steel plate.

The security level of the anti-theft door is divided into A, B, C, D, and the thickness of the steel plate is also corresponding. In general, the doors sold in the market are Grade A doors, with high security levels such as door locks and steel plates, and such doors are marked with the font size of "A" to be easily identified.

2. Look at the anti-theft door lock.

The reason why the anti-theft door can play an anti-theft role, and the door lock is the key, the higher the door lock level, the higher the anti-theft level, with the development of artificial intelligence, now many anti-theft doors are electronic locks, fingerprints or password entry systems, no longer have to be afraid of the situation without a key.

3. Look at the material and filling of the door panel.

The security door can resist pressure and play a role in sound insulation and impact protection, which is directly related to the padding inside the door panel. The anti-theft door in the market should pay attention to filling polyurethane foam, rock wool board, aluminum foil honeycomb board, pine honeycomb board, cardboard honeycomb board, and the quality of the filling directly affects the thermal insulation ability of the door and the practicality of use.

Sorting of various types of security door fillers: polyurethane foam board, rock wool board, aluminum foil honeycomb board, pine honeycomb board, cardboard honeycomb board.

There are also many materials for the production of anti-theft doors, such as cast aluminum, zinc alloy steel plate, galvanized steel plate, etc., different material door panels, anti-theft and anti-theft capabilities are different, among which the best door panel cast aluminum door, the worst is cold-rolled steel door, which is easy to be oxidized, and the quality is worrying.

In addition to the above points, the selection of anti-theft doors, but also need to look at the thickness of the door panel, which is directly related to the manufacturer's process processing, if it is a honeycomb panel filled anti-theft door even if it is thick, can not protect the safety of the owner.

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.

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.

1. Choose according to the size and opening direction of the door.

There are many sizes and specifications of the door, and users can choose the appropriate anti-theft security door according to the size of the door opening, the direction of the door opening, the color pattern, etc.

2. Pay attention to the surface quality and safety of the anti-theft door.

There are also many types of security doors, such as: steel security doors use steel plate thickness can not be less than 2 mm. The thickness of the steel plate used for the door leaf panel is in millimeters, the thickness of the door body is more than 20mm, and the weight of the door body should also be checked whether it is more than 40kg.

Check the steel seal of the security door grade, if there is no steel seal, it means that it does not meet the national standard.

3. Pay attention to the safety of anti-theft door hardware.

The hardware accessories of the anti-theft door also determine the security of the anti-theft door, so when selecting the anti-theft door, it is necessary to check whether the lock is a special lock for anti-theft that has been tested by the public security department. Whether there is a reinforcing steel plate where the lock is installed and check the performance report of the key and lock.

4. Check the structure and process of the anti-theft door.

When purchasing an anti-theft door, you should also look at the structure and process of the anti-theft door, and you can remove the cat's eye and doorbell box when purchasing, and check the internal structure of the door. There should be several reinforcing steel bars in the door to connect the front and rear panels of the door body, and it is best to have asbestos as a filling in the door.

1. Look at the anti-theft mark. If you buy a brand of security doors, then when we buy, you can carefully observe whether it has the corresponding brand logo, many "fake and shoddy" security doors do not have these logos. When we pick in the store, we can also ask the merchant to open the door and see if there is a relevant grade mark on the left side of the door frame.

The state has a unified definition of the security level of the anti-theft door, and there are four levels of "A, B, C, D", and Class A is the best, and so on. However, there are quite few Class A security door products on the market at present.

2. Look at the thickness of the steel plate. Relatively speaking, its anti-theft and the thickness of its steel plate are directly related, if the thickness of the steel plate is thicker, it means that its quality is better, and the anti-theft performance is better. The country's minimum standard for the thickness of the steel plate of the anti-theft door is the door frame.

If you want to judge the thickness of the steel plate, the easiest way is to "push, knock": knock on the door, if the sound is thick and dull, it means that the quality is better, if the sound is crisper and the search is only hollow, it means that the quality is poor.

3. Look at the locks. Door lock is a key point to judge its anti-theft, if you want to distinguish the quality of the door lock, we can understand through its grade. Generally speaking, the anti-theft lock is divided into A, B, super B level, the more complex the structure of the lock, the more complex the key pattern, the longer the lock is opened, the better the anti-theft Shipei.

If you don't know how to pick a security door, then I hope the above will help you.

Summary. 1. Select the grade of the door lock. The security of the door lock can be divided into three levels: A, B and C, of which the door lock security is the highest.

2. Choose an anti-theft door with thick steel plate. The thicker the steel plate, the better the quality of the relative door, the actual purchase process can be judged by a simple scrutiny, the steel plate is thick to push up hard, the sound of knocking on the door is very dull, if the sound is more brittle, then the quality of the anti-theft door is relatively poor. 3. Look at the quality of the process.

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

What are the precautions for the decoration of the anti-theft door1. Before purchasing the anti-theft, the sales merchant should show the "inspection certificate" of the relevant departments. See if the anti-theft door we want to choose meets the technical requirements of the national mandatory standard GB17565-1998. Check whether the lock of the anti-theft door is a special lock for anti-theft that has been tested by the public security organ.

Also check whether there is a reinforced steel plate protection in the installation position of the lock. 2. See whether the process quality of the anti-theft door is qualified, whether there are welding defects on the door, and whether the match between the door frame and the door leaf is very dense. Take a look at the weight of the security door, generally in accordance with the national standard production of the security door, its weight is not less than forty kilograms.

3. Remove the cat's eye, doorbell box or lock handle of the anti-theft door. Looking at the internal structure, the inside of the general qualified anti-theft door should have several reinforcing steel bars, and it is best to have asbestos and other fillers with fireproof, thermal insulation and other materials.

Anti-theft stamp. The new national standard changes the original three grades of the security door to four grades of "A", "B", "C" and "D", with Grade A being the highest and decreasing in turn. The anti-vandalism time of Class A security door is not less than 30 minutes, Class B is not less than 15 minutes, Class C is not less than 10 minutes, and Class D is not less than 6 minutes.

The anti-theft security level of the new national standard is represented by the letters "J", "Y", "B", "D", which are generally marked in the upper corner of the inner hinge of the anti-theft door, and the position of 1600 mm 100 mm from the ground height, and is a permanent fixed sign. When choosing an anti-theft door, be sure to see if there is this sign on the inside, if not, it is likely to be just a general steel door.

The number of lock points and the anti-theft rating of the lock. The quality of the lock mainly depends on the number of lock points, that is, the number of lock points, in the state of the anti-theft door open, when the key is twisted, the protruding point on the door leaf is the lock point. The new national standard stipulates that the number of lock points between the door frame and the door leaf shall not be less than 12, 10, 8 and 6 respectively for Class A, B, C and D security doors.

Theoretically, the more lock points, the greater the anti-prying force, but it does not mean that the more lock points, the safer the security of the security door. Because the lock points of the security door are all controlled by the lock cylinder, even if there are 12 lock points of the Class A security door, all the lock points are controlled by one lock cylinder. Therefore, when picking an anti-theft door, you should check the anti-theft rating standard of the lock.

China's current lock grade is divided into three types: A-level, B-level and super B-level, and super B-level is the best. In addition, the deadbolt length of the main lock should not be less than 16 mm.

Door thickness. Steel plate is another important criterion for judging the quality of security doors. The new national standard stipulates that the thickness of the steel plate of the anti-theft door frame should be more than 2 mm, the thickness of the door body should be more than 20 mm, and the weight of the door body should generally be more than 40 kg.

The specific thickness of the steel plate is specified as follows: grade A, B, C, and D should be 2 mm, 2 mm, mm and mm respectively. In terms of materials, copper security doors are the best and the most expensive, followed by stainless steel security doors and aluminum alloy security doors.

The internal structure of the door body. If you want to get a more complete understanding of the security door, you may wish to remove the cat's eye, doorbell box and other parts to see the condition inside. For example, you can look at the thickness of the steel, whether there is a filler that can play the role of fire prevention, sound insulation, etc., and it is best to see whether the connection between the front and rear panels of the door body is normal and there are no gaps.

Whether there is a pry guard and cat's eye protector. If you want to strengthen the security level of the security door, you can take some measures on your own. For example, add an anti-pry sleeve to the door lock, or install a cat's eye protector on the cat's eye, so that the security factor of the anti-theft door can reach a higher level.
