Mr. Gan, who lives in Xudong Road, Wuchang District, could not think of himself. Within a month of being in his own house, he was patronized by thieves three times. The most he could not understand was that he had changed the security doors of three different brands, but each time he was stolen. Open up.
"This security door is not anti-theft, I really do not know which kind of anti-theft door can be selected to prevent theft." Mr. Gan complained to the author, "My mother is afraid to sleep now, always worry about someone knocking, often midnight Nightmares wake up."
As Mr. Gan did so because of the quality of security doors, his home was stolen. I learned from the Municipal Public Security Bureau that 90% of the thefts are door-to-door and most of them are crowbars and words. Such as crime tools, the use of expansion joint pressure method. If the quality of the security door does not pass, the thief will easily succeed.
Why are there so many problems with the quality of security doors?
Professionals told the author that a quality-qualified security door should have a plate thickness of 1 mm and a door frame of 2 mm. As far as anti-theft performance is concerned, the thickness of qualified security doors is generally more than 20 mm. Reinforcement steel is to be laid in the door sandwich and filled with fillers so that the front and rear doors of the door are organically connected to reinforce the door body. The overall strength.
However, security doors produced in small workshops often use iron sheet instead of steel sheet, or use inferior boards with low cost to replace steel sheets, which results in poor extension performance of the outer door of the anti-theft door and is deformed by external forces. It is virtually useless. Once the theft elements force the use of crowbars and other devices to damage the door body, the door body steel plate deformation can eventually lose its barrier function. The lawbreakers often use some anti-theft door lock bolt short, locking points and other defects, using universal unlocking tool technology Unlocking, so that the anti-theft door locks are opened silently, in the end to achieve the purpose of the door body, door locks burglary.
The author visited several anti-theft door dealers. They are also very worried about the current situation of the anti-theft door market. “Now everyone can be a security door. Whether you have qualifications or not, 500 security doors on the market can be purchased. It is unqualified.†Mr. Jia, a dealer of a brand of security doors, said, “An anti-theft door that meets the national standards requires 600 pieces of cost, but the market is flooded with 400,500 pieces of inferior security doors.†Mr. Wen told the author that these inferior security doors will be used as "steel doors," "entrance doors," "protective doors," "prevention doors," etc. as a cover to deceive consumers.
Mr. Liu, the dealer of Wang Li’s anti-theft security door, admits to the author that because a large number of low-quality security doors flood the market, his own product quality has also declined. “I feel that the quality of security doors we are now doing is not as good as before. Why? In the fraud, you really do not know, ah!†Mr. Liu told the author angry, “Wuhan's character is the map cheaper, but know it is parallel imports but also to buy, resulting in a qualified quality security door but there is no market.†He reminded Consumers, "You may be able to buy a poor security door by a few hundred dollars, but in the long run, you may lose more."
Why is the market flooded with a large number of inferior security doors?
Manufacturers have said that a well-known anti-theft door manufacturer staff told the author that now leads to a large number of low-quality security doors flooded the market is mainly due to the high cost of anti-theft door, "in 2001 the price of steel plate is 2000-3000 yuan / ton, now rose to 6,000 yuan / Ton, some manufacturers use high cost reduction methods to reduce costs and reduce the use of steel plates. As a result, a large number of anti-theft doors with a thickness of only 0.5 mm have appeared on the market, and even 0.4 and 0.3 mm have appeared. â€
He said that in order to improve the current chaos in the anti-theft door market, it must be grasped from the source. "Who doesn't meet the standards, it will not allow you to produce. Now that manufacturers in the market have been found to be having problems, it will be fine to pay a fine and the manufacturers will continue." Production, businesses continue to sell, this is not to injure the people?†He told the author, the security door market in Wuhan, substandard products more than qualified, the national standard is virtually empty, the market has not been well monitored.
It is reported that on November 28th last year in Wuxi, a national burglar door security new standards development seminar was held by a number of experts from the Ministry of Public Security and the leading security door manufacturers in the country. Revised, three new standards such as "security doors must be stamped in the upper left corner" will be fully implemented this year.
In 1998, the State formulated the GB17565-1998 “General Technical Conditions for Anti-theft Security Doorsâ€, which required the selection of materials for anti-theft doors to meet the requirements of the standard, and clearly stated that the thickness of the door frame should reach 2.0 mm or more, and the location of the anti-theft door lock should be specified. The mandatory standards for the hinge part, the door leaf part, and the door frame part. The amendments to the original national standard were revised, including 30 minutes, 15 minutes, 10 minutes and 6 minutes for the abnormal opening time of the security door; the length of the locking tongue is not less than 16 millimeters; At 8 o'clock and so on. In response to the status quo of “security door†and “entrance door†on the security door market, the new standard states that from this year on, all security doors must be marked with a security level in the upper left corner of the door (A, B, C, D, and T) The characters of the security door are permanently fixed to the upper corner of the hinge in the form of Arial gravure, 1.60 meters above ground level, and 10 mm in positive and negative errors.
However, among the several anti-theft door dealers visited by the author, they were unaware of the new standard, and they did not see any dealers selling anti-theft doors with new marks. In this regard, the author telephoned Mr. Han, a staff member of the Technical Supervision Bureau of Wuhan City. He said that the new standard is not very clear, and Wuhan has not implemented such a standard.

Most of what we see in shopping malls are now Is a class A anti-theft security door, it is more suitable for general consumer consumers.
3, material security door from the material is mainly divided into five kinds: steel, steel wood structure, stainless steel, aluminum alloy and copper, they have their own characteristics in terms of quality and performance, natural prices are not the same.
Steel anti-theft door: It can be said that it is the most commonly seen on the market and most people use it. Most of the security doors that people are familiar with belong to this series. This type of door is cheaper and more reasonable, and its sales account for more than 90% of the total market sales. The disadvantage of this type of door is that the exterior lines are hard and it is difficult to integrate with modern interiors.
Steel-wood door: It is a kind of door that can be matched with interior decoration. Generally, it can be requested by the user. The anti-theft performance is achieved by the middle steel plate.

Stainless steel security doors: Stainless steel security doors are rugged and more secure.
