At present, there are many brands of security doors on the market, the prices are different, and the services are different, so that more consumers can choose when buying security doors. In this regard, Chengsou.com and the Beijing Consumers Association, China Consumer News and Newspapers Co., Ltd. launched the “2014-China Anti-theft Security Door Consumer Knowledge Survey Activityâ€.
Five parts of the activity design: the status of the security door, the security level of the lock and the security knowledge, the security door brand and price advantage comparison, the security door product quality and after-sales service, consumer satisfaction ranking; the security door brands involved are Wang Li, Xingyue God, Sunshine, Xinduo, Wanjia, Panpan, Longjia, Huajue, Buyang, Feiyun, Qunsheng mainstream brands.
The activity aims to improve consumers' understanding of anti-theft security door knowledge, recommend a number of high-quality anti-theft security door brands for consumers to choose and display anti-theft security door brand and technology strength, and guide consumers to safe consumption.
The security door is called the “anti-theft security doorâ€. Since the first publication in the 1990s, the demand has increased at a rate of 13.9% per year. The demand for the door industry is 170 million square meters per year; the material develops from iron gates, steel doors and aluminum alloy doors to stainless steel doors and copper doors; in appearance, from the first generation of ordinary doors to European doors and wide-edge doors. The sixth generation of decorative doors, from the lines, the surface, the overall innovation. According to the survey, most of the enterprises in the security door industry are based on engineering orders, and the real retail market has a small share. Due to industry characteristics, security doors are largely produced on a large scale. As a result of this large-scale production, the security door is becoming less and less individualized, and the homogenization is serious, resulting in a decrease in the industry's profit margin. In addition to the similarities in products caused by large-scale production, the lack of innovation in enterprises is also an important reason for product homogeneity.
In the past two years, the security door has been continuously innovated in terms of technology, structure, business model and concept. The impact and impact on the original market is undoubtedly huge. This is also the fundamental reason for the prosperity of China's security door industry.
Over the past 20 years, the development of China's security door has become more saturated with the development of the four major sectors of the Pearl River Delta, the Yangtze River Delta, Sichuan Chengdu and the Bohai Sea. With the rapid development of the above-mentioned regions over the years, local security door enterprises are faced with a series of problems such as scarcity of land, rising labor costs, rising logistics costs, and lack of environmental protection, which have become the bottleneck restricting the development of security door enterprises.
Stainless steel door share rises
At present, the anti-theft security level of the security door is divided into four levels: A, B, C, and D. The letter codes are J, Y, B, and D, respectively. A is the highest level, which is decremented in turn. Among them, the stainless steel security door gradually replaces the ordinary security door, wooden door and solid wood door in the middle and high-grade decoration field. According to incomplete statistics, the output value of stainless steel security doors accounts for nearly 30% of the entire door industry.
Centralized industrialization
At present, the total number of enterprises in China's security door industry has exceeded 5,000. Zhejiang Yongkang, which takes “China Gate Capitalâ€, has gathered more than 450 security door enterprises including Wang Li, Hua Jue, Wan Jia, Qun Sheng and Xin Duo. With an annual output of more than 25 million baht of various types of products, exports more than 7 million baht, accounting for 70% of the national security door production.
The security door is implemented in the national standard, and the requirements for materials and safety are higher than those for the general implementation of enterprise standard protective doors and steel doors. In addition, the production cost of the security door is sensitive to price fluctuations of metal raw materials. Environmental protection door into the mainstream trend
As a major part of building energy consumption, security doors play a key role in building energy efficiency. It is understood that the security door accounts for 40% of the building energy consumption. At present, there are many production methods for ordinary living room doors, but most of the processes are cumbersome and expensive, and there are widespread problems in performance such as fear of fire, easy deformation and cracking, and easy release of formaldehyde. People's pursuit of durable, healthy and environmentally friendly home is the unchanging rule of market consumption.
Security door manufacturers should follow the development of the times and vigorously develop energy-saving and environmentally-friendly security door products, so that they can achieve better development in the low-carbon era.
Marching to the west is the way out
According to the survey, there are fewer and fewer orders for large cities, but there are large markets in the less developed regions such as the central and western regions, northwestern regions, and northeast regions. The reason is closely related to the development of the real estate market. In the past few years, the domestic security door industry operated the market with 35% of foreign sales, 55% of engineering, and 10% of retail sales.
Take Henan Province as an example. Three years ago, most local enterprises mainly used low-end non-standard doors in the rural market. Since 2009, there have been more than ten security door and fire door companies, and the starting points have been compared. High, the planned daily production capacity is mostly above 500é•—. It can be seen from the development of these enterprises that the Midwest market is rapidly emerging.
The first part of the lock security level
Cylinder level standard
In addition to the security door itself, the door lock is also the key to theft prevention. The state divides the security door lock cylinder into three levels: Class A, Class B and Class B (Class C). Different door lock keys are different. High, the greater the anti-theft coefficient.
Class A lock cylinders generally include traditional one-word locks, cross locks, crescent locks and locks in most lock cylinders with only one row of marbles. The anti-theft is poor, and the opening time is usually from a few seconds to two minutes. Many developers The lock cylinders of the house fashion are all A-level.
Precautionary Guide: A-level lock is the key target of the thief. It can be opened with iron hooks and iron pieces, no more than 1 minute, and the fastest one or two seconds. The police recommended that the Class A lock cylinder should be replaced with a Class B lock with better anti-theft performance. In addition, a latch can be added to the door.
The B -class lock cylinder generally includes a lock with a double-row marble structure and a lock composed of a single row of marbles and blades, and the anti-theft property is general. It takes 1-5 minutes for a professional locksmith to open. The B-class lock key is a flat-panel key with a double-row marble slot. The difference with the A-class lock is that there is a row of curved and irregular lines on the key surface. The main types of lock cylinders are 3 types, computer double-row lock core, double-row crescent lock core, double-sided vane lock core. The anti-technical opening time is 5 minutes, and the mutual opening rate is high. With a strong twist tool, the lock cylinder can be opened in 1 minute.
Precautionary Guide: For now, most of the communities use B-level locks. The public can upgrade and replace them with Super B-class locks that can prevent all technical opening. It can be purchased at a regular lock company with a record, and the price is only one or two hundred yuan.
The super B-class lock cylinder generally includes a lock with a combination of multiple rows of marbles and multiple rows of blades, and a lock with a full blade and a side column structure. The anti-theft effect is best in the current three types of lock cylinders.
The shape of the key is a single-sided blade inner milling slot or an outer milling slot key. The lock cylinder type is a side cylinder lock core; it can not be technically opened after 270 minutes of inspection by the Ministry of Public Security, and the regional mutual opening rate is zero (one million and one million) . The structure of the marble is locked by the double row of blades and the V-shaped side column; if the lock cylinder is opened by a strong twisting tool, the internal core of the lock cylinder is broken, and the self-explosion is locked, resulting in failure to open. Because it is not easy to open, the anti-theft coefficient is the highest.
Lock core level
Than thickness. The thickness of the steel plate determines the strength of the impact resistance. The thickness of the cold-rolled steel sheet of the door frame is 2 mm, 2 - 1.8 mm, 1.8 - 1.5 mm and 1.5 mm, respectively. The thickness of the outer wall of the door leaf is 1 mm, 1 mm, 0.8 mm and 0.8 mm, respectively. The thickness of the inner panel of the door leaf is 1 mm, 1-0.8 mm, 0.8 mm and 0.6 mm, respectively.
Than filler. The state stipulates that the worst security door should use honeycomb paper as the filler. The grade A door is different according to the brand, and the filler is different. Some are aluminum silicate rock wool (fireproof cotton), some are aviation honeycomb aluminum, and some are aluminum foil. Grade A security doors are usually made of aluminum silicate wool and aluminum foil. Aluminum silicate rock wool has good thermal insulation, fireproof and sound insulation properties. The aluminum foil is light in weight, corrosion resistant, non-toxic and tasteless, and has good thermal conductivity, heat resistance and low temperature resistance. Under normal circumstances, the second-grade security door is made of rock wool and polyurethane foam. The advantage of rock wool is that it has a good flame retardant function and is a poor conductor of heat. The polyurethane foam has no gap after filling, and the bond is strong after curing. Shockproof and compressive, no cracking after solidification, no corrosion, no shedding, ultra-low temperature thermal conductivity, and heat resistance. Efficient insulation, sound insulation, waterproof and moisture proof after curing. The general market for both grade C and butyl grades is honeycomb paper, which has essentially no insulation, fire and sound insulation properties.
Than locks. The anti-theft lock is the most important part for the door. The performance of the anti-theft lock is directly related to the safety of the door. The security door produced by the regular manufacturer will have a "safety level imprint" in the upper left corner of the door. The anti-theft level of the Class A anti-theft door lock is Class B, which is the advanced protection level; while the B, C and D-class security doors have the anti-theft level of the anti-theft door lock core of Class A, that is, the general protection level. The vandal-proof time is clearly different because of the different levels. Grade A is not less than 30 minutes, Grade B is not less than 15 minutes, Grade C is not less than 10 minutes, and Grade D is not less than 6 minutes. At the same time, observe the number of locking points between the door frame and the door leaf. The security doors of A, B, C and D should be no less than 12, 10, 8 and 6 respectively.
The second part of security knowledge: locks purchase and maintenance
Lock purchase
The safety level of the lock cylinder will decrease year by year, preferably every 3 to 5 years. First of all, we must recognize whether the product has a factory name, site, trademark and whether there is a qualified inspection report issued by a professional quality inspection agency.
Secondly, the lock should be clear in appearance, the surface is not rough, and it feels comfortable. The lock is opened and rotated flexibly, the locking device should be functional, and the feeling of failure cannot be felt when the hand is felt, and the security performance is good.
Third, the material should be moderate when purchasing, and the hand should be firm and reliable. Do not use all kinds of locks made of inferior materials with low quality.
Fourth, the installation of the lock is also a key: the installation should be carried out in strict accordance with the product manual, to recognize the installation center distance, the scope of application and the opening method of the lock. Special care must be taken not to install on wooden doors with high humidity to prevent corrosion of harmful substances.
Fifthly, the lock body is often kept clean to prevent foreign matter from entering the lock cylinder, causing rolling when opening, and even the lock cannot be opened.
In addition, when selecting the security door, you should also grasp the following points to identify the anti-theft lock with high anti-theft coefficient:
1. Look at the "teeth" of the key. The more teeth, the deeper the teeth, the more complicated the arrangement, the more difficult it is to open, and the better the anti-theft performance.
2. Pick the lock on the pound to say two, one to see the lock core than the weight two. The heavier the weight, the better the quality of the lock cylinder. The more beads in the lock cylinder, the better the anti-theft function.
3. Select the lock core to see the color, look at the work than the color. The quality of the lock cylinder is electroplated, the surface is smooth and the color is bright. Among them, the color is dark yellow, the copper core is relatively strong, the anti-theft performance is better, the color of the lock core is dim, the color is gray and the bubble is zinc alloy, and the anti-theft performance is general.
4. The key rotation is inserted into the lock cylinder. The anti-theft performance of the card is poor. After the key is half-inserted, use 5 to 7 minutes to rotate clockwise or counterclockwise and continue to press the key into the lock. The key of the card indicates that the lock core has poor anti-theft performance. The instructions for inserting the lock cylinder smoothly in the semi-rotation state are good.
Daily maintenance
After the security door protection film is removed, the door body is placed in the outdoor environment. Because dust, oil and other contaminants adhere to the door body, the door body fades and loses the fresh light brightness. It is recommended that the user clean it once every certain period, and the cleaning method is used. 70% water mixed with 30% of the cleaning solution is placed in the sprayer, sprayed evenly on the door surface, and gently wiped with a soft cloth.
1. When the key cannot be fully inserted into the keyhole when opening the door, in the winter, first check whether there is ice in the keyhole. In other seasons, check whether there are other foreign objects in the keyhole, and inform the situation in time.
2. If it is difficult to insert the lock cylinder when opening the door, you can apply a little graphite; or insert the lock core with the pencil lead.
3. Always keep the lock body transmission parts with lubricant to keep the transmission smooth and prolong the service life. It is recommended to check once every six months or one year, and check if the fastening screws are loose to ensure the fastening.
4. When the lock is in use, periodically (half year or year) or when the key is not inserted smoothly, a small amount of graphite powder or pencil powder can be put into the lock cylinder to ensure the key is inserted and removed smoothly. However, do not add any other oil to lubricate to prevent the grease from sticking to the marble spring, causing the lock to not rotate and not open.
5. Check the matching clearance between the lock body and the lock plate. The fit between the lock tongue and the lock plate hole is appropriate. The clearance between the door and the door frame is preferably 1.5mm-2.5mm. If changes are found, adjust the position of the hinge or lock plate on the door. At the same time, pay attention to the thermal expansion and contraction caused by seasonal changes, to ensure that the clearance between the door and the door frame, the lock body and the lock plate is reasonable, so as to ensure the smooth use of the lock.
6. In the severe cold area, the problem of “wintering†of the security door is also very important, because the indoor and outdoor temperature difference in the severe cold area is very large, and it is easy to make the lock core of the security door damp when it is hot and cold, and then freeze it. The situation occurs, before the arrival of winter, it is necessary to drop two drops of antifreeze oil in the lock cylinder, and then use gasoline or diesel to clean in winter. Vegetable oil is not available as a lubricant for the lock cylinder.
