Real Estate Portal-Soufang.com》Decoration Forum》Decoration Forum Because the anti-theft door as a whole is compounded together, it is difficult for the people to use certain means to detect, so how can ordinary people buy a reasonable and effective anti-theft door? Industry insiders put forward some suggestions: the steel plate of the qualified anti-theft security door frame is more than 2 mm; The internal filling of the door body can also be checked by removing the cat's eye, the doorbell box or the lock handle, etc., and there are several reinforcing steel bars inside, so that the front and rear door panels of the door body are organically connected together, and the overall strength of the door body is enhanced; It is best to have asbestos and other materials with fireproof, thermal insulation and sound insulation functions as fillers in the door; It is necessary to check whether the lock adopts the special lock for anti-theft that has been tested by the public security department, and whether there is a reinforced steel plate for protection at the installation place of the lock; It is necessary to 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, whether the gap is uniform and consistent, whether the opening is flexible, etc.

I believe that everyone is familiar with the security door, it is more protective of our personal and property safety, but there are many types of security doors, many brands, it is conceivable that the quality is uneven, and the security door is the most important security guarantee for home life, so what should be paid attention to when buying an security door? Here are 6 things you need to keep in mind.

1.Look at the level of security.

The national standard of anti-theft door is divided into anti-theft security levels according to the length of anti-theft door anti-destruction time, plate thickness and other indicators, which are divided into 4 levels: A, B, C, D, and A, with A being the highest level.

2.Look at the number of locking points.

The number of locking points for the four levels of security doors cannot be less than 12, 10, 8 and 6 respectively.

3.Look at the locks.

According to the new national standard, the lock of the anti-theft door should be able to open the door during the anti-vandalism time, even if the lock cylinder is drilled off and the deadbolt is loosened. It should also be noted that the effective length of the main deadbolt extension of the security door should not be less than 16 mm, and there should be a deadbolt stop device.

4.Look at the thickness of the door frame.

The thickness of the door frame steel plate of grade A, B, C, and D is 2 mm, 2 mm, mm and mm, respectively.

5.Look at the anti-vandalism time.

The anti-vandalism time of different levels of security doors is not the same, Class A security doors are 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.

6.Look at the authenticity identification mark.

The national standard for security doors stipulates that security doors should have permanent fixed markings. The marking symbol is a phonetic letter, from left to right, the anti-theft security door code, the anti-theft security level and the enterprise-defined features. FAM stands for security door, such as FAM-J-WS D2750 represents a certain model of Class A security door of a certain enterprise.

The above shared the purchase of anti-theft doors 6 points, they are one to see the security level, the second is to see the number of locks, the third is to look at the lock, the fourth is to look at the thickness of the door frame, the fifth is to look at the destruction time, the sixth is to see the authenticity identification mark, in addition, I recommend that when you buy an anti-theft door, you should compare more and buy the best quality anti-theft door.

First, the installation of the anti-theft door is best to remove the original wooden door frame, the quality of the brand anti-theft door is good, the installation of the anti-theft door is not long, provided that you go to the door in advance, because the size of the previous house door opening may not be in line with the anti-theft door, you first go to the dealer to consult, provide the size of your door opening, or ask the dealer to measure it. <>

II.1The regulation of the anti-vandalism time of the anti-theft door.

The above anti-vandalism time refers to the time required to prevent the opening of an opening of not less than 615c penetrating the door leaf on the non-steel sheet door.

Grade A is greater than 30 minutes, Grade B is greater than 15 minutes, and Grade C is greater than 10 minutes.

2.The level of the lock.

The levels of locks are divided into A, B, and C levels, as follows:

Class A lock: At present, the Class A anti-theft lock key on the market mainly includes a word key and a cross key. The internal structure of the A-grade lock cylinder is very simple, limited to the variation of the pin, and the marble groove is few and shallow.

The anti-technical opening time is within 1 minute, and the professional can open it within 30 seconds, and the mutual opening rate is extremely high, and it cannot be upgraded. The marble structure is a single row of marbles or cross locks.

C-level lock: At present, the safer one on the market is the C-level lock cylinder, which adopts a double-row, computer, and composite curve groove patent key, which cannot be opened in 270 minutes. Among them, the C-level lock cylinder is used more in the financial industry and less civilian.

3.Misunderstanding of security doors - the thicker the door, the better.

For security doors, it is generally believed that the thicker the door leaf, the better, but in fact, this may be wrong.

For the door leaf, the specification is nothing more than the provision of opening holes in the non-wooden door leaf, and the minimum time limit for the time limit of the Grade A door is only 30 minutes.

At present, the market is generally steel doors, not to mention whether someone is holding a cutter or a sledgehammer to smash the door, it is not easy to make a hole in the steel door.

In fact, the anti-theft door is more often "anti-gentleman, not anti-villain". If you really hit it with a sledgehammer, you can knock down any door. Therefore, relying solely on the thickness of the security door to prevent theft is actually one-sided. <>

3. Anti-theft lock test report.

It should be noted that the time of anti-violent opening and anti-technical opening is tested under standard laboratory conditions, and the actual protection ability has a lot to do with the tools used and the technology of the lockpicker. Generally speaking, the door is the easiest to be technically opened when there is no anti-lock, so you must be anti-locked when you go out, and you must be insured when you sleep! Therefore, you must lock it when you go out, and you must be insured when you sleep!

Therefore, you must lock it when you go out, and you must be insured when you sleep! Say the important thing three times.

In fact, there are many details of the national standard of the anti-theft door, but it is not easy to understand if it is too detailed, as long as you remember to look at the product test report, the second look at the grade steel seal, and the third look at the product name, you can basically judge whether the door is really an anti-theft security door. <>

It should be noted that to buy a more secure security door, the fingerprint security door is the safest. Then you have to choose according to the brand of the security door.

The lock cylinder level of the anti-theft door should be above A, and it is best to have no door mirror, so that the security level of the anti-theft door is sufficient.

First of all, we should pay attention to the quality and safety of the door, and also pay attention to the things that must be paid attention to on the invoice contract, whether the structure is reasonable, and whether the lock is very flexible when unlocking.

We should choose some security doors, and we should choose the kind that is sturdy and durable, and the quality is also very good.

It is necessary to pay attention to the material of the anti-theft door, as well as the security level coefficient of the anti-theft door, and also pay attention to whether the lock of the anti-theft door is strong and damaged, and also pay attention to the brand of the anti-theft door.

It should be noted that the material of this door must be strong and the safety must be good, so that it can be used at home.

1. Consumers should choose the appropriate anti-theft security door according to the actual requirements of the door opening size, opening direction, color and pattern of the room.

2. Anti-vandalism function is the most important function of anti-theft security door, when purchasing, you can require the seller to show the relevant departments of the test certificate, the product quality should meet the technical requirements of the national standard GB17565-1998 "General Technical Conditions for Anti-theft Security Door".

3. Brand guarantee: brand is the symbol 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.

Consumers should also pay attention to the "FAM" mark, enterprise name, implementation standards and other contents of the anti-theft door when purchasing, so that the door that meets the standards can be both safe and reliable.

4. The thickness of the steel plate of the qualified anti-theft security door frame should be more than 2mm, the thickness of the door body is generally more than 20mm, the weight of the door body should be checked, generally it should be more than 40kg, and the internal structure of the door body can be checked by removing the cat's eye, the doorbell box or the lock handle, etc., the thickness of the steel plate of the door body should be above, and there are several reinforcing steel bars inside, so that the front and rear panels of the door body are organically connected together to enhance the overall strength of the door body, knock on the door body with your hand to make a "knock" sound, and consumers should be flexible when opening and closing the door with their hands.

5. Check the quality of the process: special attention should be paid to checking whether there are welding defects, such as open welding, unwelding, missing welding, etc. See whether the fit between the door leaf and the door frame is dense, whether the gap is uniform and consistent, whether the opening is flexible, whether all joints are dense, the surface of the door panel should be treated with anti-corrosion, generally should be painted and sprayed, the surface of the paint layer should be free of bubbles, uniform color, most doors are also embedded with rubber sealing strips on the door frame, and there will be no harsh metal collision sound when closing the door.
