Security door price

　　Many people will ask online, is the price of the security door that every household needs expensive? In fact, the price of security doors can’t be generalized. The cheap ones are 300-500 yuan (without clothes) and the good ones are 1000-2000. The price of security doors depends on the brand you choose.

　　Every family has security doors. What should we pay attention to when purchasing security doors?

　　(1) When purchasing security doors, consumers should choose the appropriate security door according to the realistic requirements such as the size of the door opening, the opening direction and the color pattern.

　　(2) Anti-shattering function is the most important function of anti-theft safety door. When purchasing anti-theft door, the seller can be required to show the inspection certificate of the department, and the product quantity should meet the technical requirements of gb-2007 "General Skills Conditions for Anti-theft Safety Door".

　　(3) The thickness of the steel plate of the frame of the passing anti-theft safety door should be above 2mm, and the thickness of the door body should be above 20mm. The weight of the door body plate should be above 40kg, and the internal layout of the door body can be checked by removing the cat’s eyes, doorbell box or lock handle. The thickness of the steel plate of the door body should be above 1.0mm, and there are several reinforcing bars in it, so that the front and rear panels of the door body are organically adjacent to each other to enhance the overall strength of the door body. It is best to use asbestos and other materials with fire prevention, heat preservation and sound insulation functions as fillers in the door. Knocking on the door body by hand makes a "thumping" sound, and consumers should be flexible in opening and closing the door by hand.

　　(4) Inspection of process quality: Special attention should be paid to checking whether there are welding defects, such as open welding, no welding and missing welding. See whether the fit between the door leaf and the door frame is compact, whether the gap is uniform and consistent, whether it is flexible to open, and whether all joints are compact. The appearance of the door panel should be punished by anti-corrosion, generally, it should be painted and sprayed with plastic, and the appearance of the paint layer should be bubble-free, with uniform color. Most doors are embedded with rubber caulking strips on the door frame, so that there will be no unpleasant sharp and pertinent metal collision when closing the door.

　　(5) Locks inspection: generally, the security doors that pass the inspection by the public security department adopt special anti-theft locks, and at the same time, the locks should be protected by steel plates with a thickness of more than 3.0 mm.. At present, the special anti-theft lock is probably a multi-directional lock. Its advantage is that not only the door lock is locked, but also the upper and lower rails can be inserted and locked to fix the door. Greatly improved the anti-prying performance of the door. Ga/t73-94 Mechanical Anti-theft Lock promulgated by the Ministry of Public Security clearly stipulates that the anti-theft lock for mechanical thieves can be divided into ordinary protection levels and advanced levels, which are represented by Grade A and Grade B.. A-class lock refers to a lock with an anti-smashing opening time of not less than 15 minutes and an anti-skill opening time of not less than 1 minute, and B-class lock refers to a lock with an anti-smashing opening time of not less than 30 minutes and an anti-skill opening time of not less than 5 minutes (anti-skill opening refers to the ability of lock professionals to apply special things and use operation tricks to open locks). And in a uniform scene, the safety performance of class B anti-theft lock is five times that of class A lock.

　　(6) Brand guarantee: Brand is the mark of product quantity and service. Brands mainly refer to security door brands and dealer brands. When buying security doors in the market, it is best to buy them in regular large-scale home building materials chain markets. When purchasing, we should also pay attention to the "fam" mark, enterprise name, implementation specifications and other contents of the security door, so that the door that meets the specifications can be both safe and reliable.

　　(7) After installing the security door, the user should first check whether the accessories and materials such as keys, insurance policies, invoices and after-sales service lists are consistent with those provided by the security door manufacturer, and never show the situation of missing keys. When the lock installed in the door body is opened with the key, the lock core should be easy and flexible, without jamming; In the process of opening the door 90, it should be flexible and free from jamming and abnormal noise.

　　When purchasing a security door, we should focus on the anti-theft performance and quality, and check from the following key parts:

　　Check the performance and layout of door locks.

　　Select the anti-drilling lock head. After the drill bit is drilled into the lock hole, the lock head will follow the drill bit to twist synchronously when twisting, which can play the role of preventing the lock head from being crushed. Locks require a three-directional locking layout, with three hinges for a single door and six hinges for a double door. The door leaf and the frame of the door are locked. Even if the hinges are chipped off, the door cannot be opened.

　　Number of locking heads and inserting rods at the door

　　It is best to choose a door with two locks and two plungers, even if it can be crushed, it will delay the time. Generally speaking, a lock head can control 3-4 root cutting bars, so the door has poor anti-theft performance. Once the lock head is damaged, several root cutting bars will be ineffective at the same time.

　　Look at the thickness and area of the reinforcing plate around the lock.

　　Security doors can be divided into two types in layout design: closed type and grating type. No matter which one is chosen, the lock is the primary part of theft and crushing, so the guard plate of the lock should be a cold steel plate with a thickness of more than 2 mm, and the height of the guard plate should not be less than 500 mm.

　　See how the process quality is.

　　The choice of material for security door is the foundation, and the quality of manufacturing process is the key. Special attention should be paid to checking whether there are welding defects, such as open welding, incomplete welding, missing welding and slag inclusion. See if the fit between the door leaf and the door frame is dense, the gap is uniform, the opening is flexible, all the joints are feeding, and the paint electroplating is uniform, firm and smooth.

　　Select from the design.

　　Security doors on the market are classified into three categories: luxury, mid-range and ordinary. The luxury panel is made of stainless steel plate, the main frame is made of stainless steel square tube, and the decorative grid is made of stainless steel profiles; The mid-range type generally adopts the combination of Fiona Fang iron materials and floral decorations; Ordinary type is made of square steel tube, round iron and flat steel (16×4 mm). Users can choose their favorite type according to their own situation.

　　In addition, when installing the security door, it is required to fix it with expansion bolts and weld it with electric welding. There are not less than 8 fixing points, four on each side. In terms of maintenance, it is advisable to add oil to the door shaft and the plunger every 3-6 months to make them open flexibly, but do not add oil to the lock head to prevent dust from affecting the performance of the door lock.

　　Four factors to be considered when purchasing security doors;

　　Pay attention to one, pass the certificate when buying security doors.

　　Real security doors must be tested by legal testing institutions in accordance with the specifications, and there is a safety skill prevention product permit issued by the safety skill prevention department of the provincial public security department (bureau) where the production enterprise is located.

　　Pay attention to the second, security level when purchasing security doors.

　　According to the relevant specifications, the security levels of security doors can be divided into Grade A, Grade B and Grade C, among which Grade C has the highest security performance, followed by Grade B and Grade A is the lowest. Most of the security doors we see in the building materials market are Grade A security doors, which are generally suitable for ordinary families.

　　All-steel, flat-open, fully-enclosed security door, with the cooperation of ordinary machinery, hand-made things and portable electric things, its weakest link may be equal to or greater than 15 minutes when it is open, or it should not be possible to cut a 615-square-centimeter hole through the door body.

　　Pay attention to the purchase of security doors. Third, the locks are firm.

　　Passing security doors generally adopt three-directional locks or five-directional locks. Not only the door lock is locked, but also the upper and lower rails can be inserted and locked to fix the door. Most doors are also embedded with rubber sealing strips on the frame of the door, so that when the door is closed, there will be no unpleasant sharp and pertinent metal collision sound.

　　Pay attention to the quality of workmanship when purchasing security doors.

　　Special attention should be paid to checking whether there are welding defects, such as open welding, incomplete welding and missing welding. See if the fit between the door leaf and the door frame is dense, the gap is uniform, the opening is flexible, all joints are dense, and the paint plating is uniform, firm and smooth.

　　Four points for attention in choosing anti-theft:

　　First, while considering the price and appearance, we should pay more attention to the quantity of products, and buy brand security doors in the promised building materials market;

　　Second, when purchasing, you should check the inspection complaint of the security door provided by the planner, and the test results should conform to GB-1998 "General Skills Conditions for Security Doors", especially if you want to check whether the production batch number and model specifications on the complaint are the same as the goods;

　　Third, when purchasing, we should distinguish between security doors and metal doors (entrance doors, steel doors, etc.). Don’t easily believe the propaganda of the sales staff. When ordering, the planner should indicate the security door in the name column of the goods in the business, in case the illegal planner sells products such as "steel doors", "entrance doors", "guard against protection doors", "anti-pry doors" and "armored door" that are not security doors.

　　Fourth, when installing, consumers should first check whether the appearance of the security door is the same as the order sample, and ask the delivery personnel for bail card repair, invoices and other documents, so as to present problems in real time in the future.
