What is the most important part of home improvement? Many people will choose "anti-theft door". Without a reliable and safe door, this new house is indeed not reassuring to live in, but, you know, there are many famous security doors of all kinds.
The entrance door is not equal to the security door
Many consumers are a little confused when buying anti-theft doors. In addition to anti-theft doors, there are also steel entry doors, burglar-proof doors, and armored doors on the market, which seem to be more powerful than anti-theft doors. , Is the anti-pry door equal to the anti-theft door?
In the real home, the reporter asked a number of anti-theft door dealers on this issue, only Panpan anti-theft door dealer clearly told reporters that the entrance door is not the same as the anti-theft door, "the full name of the anti-theft door is the anti-theft security door, only in line with the national security door. A door that is a standard security door can be called a security door.”
So, why are there so many "fake anti-theft doors" in the market? According to industry insiders, according to the standard of "General Technical Conditions for Anti-theft Security Doors" issued by the Ministry of Public Security, the door frame, door leaf, anti-theft lock and other components of the anti-theft door are very important. strict requirements. For example, after the door leaf is subjected to a soft impact load of 30 kg sandbags for 9 times, there should be no concave deformation greater than 5 mm. The quality of the security door is difficult to pass. This has led some "smart" companies to come up with ways to "change their names". Therefore, consumers must be vigilant.
According to experts, on the surface, metal entry doors with the same appearance are no different from anti-theft doors, but the internal quality is very different. In practical applications, there is no anti-theft function at all, and there are no provisions for such products in national standards. , and its quality is customized by the enterprise itself. Compared with anti-theft doors, the metal entry door frame, door leaf and around the lock lack reinforcement plates and ribs, but the price is much lower than the anti-theft doors produced by regular manufacturers.
The Beijing Consumers Association also solemnly reminds consumers to distinguish the difference between anti-theft security doors and metal doors (entrance doors, steel doors, etc.) when purchasing, and do not believe in the propaganda of sales staff. When ordering, operators should note the product name column. In order to prevent illegal operators from selling "steel doors", "entry doors", "protective doors", "anti-pry doors", "armored doors" and other products as anti-theft doors.
Security doors must also have a certificate
So, is it true that the products marked as "anti-theft doors" must be qualified? Not necessarily, according to the results of the quality supervision and random inspection of anti-theft door products announced by the General Administration of Quality Supervision, Inspection and Quarantine recently, the products produced by large and medium-sized enterprises are of good quality, but Small business products still have 6.5% of security doors that are not burglar-proof.
Security doors also require a diploma. The real anti-theft door must be tested and qualified by the statutory testing agency according to the standard, and have the safety technology prevention product approval certificate issued by the safety technology prevention department of the provincial public security department (bureau) where the production enterprise is located. The "General Technical Conditions for Anti-theft Security Doors" formulated by the Ministry of Public Security clearly points out that anti-theft doors refer to doors with special locks and anti-theft devices that can resist abnormal opening within a certain period of time. That is to say, a door that cannot be opened by ordinary tools such as chisels, screwdrivers, crowbars, and portable power tools such as hand drills within 15 minutes is considered a real "iron general".
In terms of security level, the security of anti-theft doors is divided into three levels: A, B, and C. C-class security doors have the highest performance, B-class is the second, A-class is the lowest, and most of them are A-class in the market, which is generally applicable to ordinary families. A-level requirements: all steel, flat open and fully enclosed, under the interaction of ordinary mechanical hand tools and portable power tools, the weakest link can resist abnormal opening for a net time of ≥ 15 minutes, or it should not be able to cut a piercing Through the door body 615 square centimeters hole.
The structure is the body
There are two main factors that affect the performance of anti-theft doors, whether the structure is strong enough and whether the door lock is safe enough.
The thickness of the steel plate of the qualified security door frame should be more than 2 mm, the thickness of the door body is generally more than 20 mm, there are several reinforcing ribs in the interlayer of the door body, and the well is filled with fillers such as foaming agent, asbestos, honeycomb cardboard, etc. The front and rear panels of the door body are organically connected to enhance the overall strength of the door body. When the door body is knocked with an object, it will make a "dongdong" sound.
The more popular anti-theft door with steel and wood structure in the market is the solid door with steel plate and wooden board, which has achieved the user's wish that the anti-theft door will not only not be "broken in", but also "gold and jade outside". This kind of door uses a steel door frame, and several reinforcing steel bars are installed to fix it in the wall; the front and rear of the door leaf are sealed steel plates, and the three sides have anti-pry edges; there are high-impact honeycomb partitions in the steel plates to make the door The front and rear panels of the body are organically connected together, which is safe and environmentally friendly, and greatly enhances the rigidity and impact resistance of the door panel; the multi-directional anti-theft lock with up to 15 locking points is installed in the steel plate, and the locking points are all over the four sides of the door. Coupled with the lock lever of heaven and earth, it can be said to be impregnable; there is also a reinforced steel plate in the lock position, which is not easy for general tools to penetrate. Surrounding the steel plates at the front and back are high-strength craft wooden panels, with a concave-convex three-dimensional design, similar in appearance to logs.
The lock is the heart
A good security door not only needs to be made of sturdy materials, but also needs a good lock. Otherwise, a door that cannot be destroyed by external force for half an hour can be picked up in 1 minute, and the "anti-theft" function will be out of the question.
According to industry insiders, anti-theft door locks must be anti-theft locks that can be opened or locked indoors and outdoors, and a 2 mm thick protective steel plate is installed outside the lock cylinder. There are only two types of locks used in anti-theft doors. The anti-destructive opening of A-class locks is more than 15 minutes, and the anti-technical opening is more than 1 minute; while the anti-destructive opening of B-class locks should be more than 30 minutes, and the anti-technical opening is more than 10 minutes. 5 minutes. Since the cost of B-class locks is much higher than that of A-class locks, most manufacturers in the market are using A-class locks.
In addition to the level of locks, also pay attention to the type
At present, the anti-theft doors on the market are divided into two types of matching anti-theft door locks. One is A and B key anti-theft door locks, and the other is smart door locks. The anti-theft door with A and B keys provides convenience for new house decoration households. During the decoration, the workers use the A key to open the door. After the decoration, the owner only needs to insert the B key into the lock hole, and the A key will be scrapped.
The magnetic key anti-theft door lock of the automatic anti-theft device is the mainstream product on the market, but the quality is different. The magnetic keys with better quality generally cannot be copied (except for the configuration in the factory by the password), and the owner does not need to replace them after the decoration workers use them. In addition, the automatic anti-theft door lock with good performance starts automatically anti-theft from the moment it is closed. The key is magnetic, and the so-called master key is difficult to work on it.
Five kinds of materials for security doors
When purchasing anti-theft doors, consumers not only hope to prevent theft, but also want to play a decorative role. Therefore, they need to choose the material of the anti-theft door according to the style of home decoration. At present, there are five main materials for security doors: steel, steel-wood structure, stainless steel, aluminum alloy and copper. They have their own characteristics in quality and performance, and their natural prices are also different.
★Steel security door: It can be said that it is the most seen on the market and the most used by the common people. Most of the anti-theft doors that people are familiar with belong to this series.

★Stainless steel anti-theft door: The stainless steel anti-theft door is durable and safer. At present, the color of stainless steel anti-theft doors on the market is too monotonous, basically silver-white. This color makes people feel very stiff, and it is not easy to coordinate with the door and the surrounding environment, and if there are collisions and welding marks on the surface, it will be very difficult. obvious. Due to the price factor of stainless steel itself, its price positioning is also higher.
