Anti-theft door market
  Mr. Gan, who lives in Xudong Road, Wuchang District, could not have imagined that he had been patronized by a thief three times within a month. The thing that made him most incomprehensible was that he had changed three different brands of anti-theft doors, but every time he was stolen, he was stolen. Pry it.

"This anti-theft door is not anti-theft at all. I really don't know what kind of anti-theft door to choose in order to prevent theft." Mr. Gan complained to the author. "My mother doesn't dare to sleep now. She is always worried about someone prying the door. Nightmares frightened. "

  There are not many cases of stolen homes such as Mr. Gan because of the quality of anti-theft doors. The author learned from the Municipal Public Security Bureau that 90% of the thefts are thefts by prying the door, most of which are started with a crowbar. And other crime-making tools, using the method of expanding and prying pressure. If the quality of the anti-theft door is not high enough, the thief will easily succeed.

Why is there a problem with the quality of so many security doors?

Professionals told the author that for an anti-theft door of qualified quality, the thickness of the steel plate of the door leaf should reach 1 mm, and the door frame should reach 2 mm. In terms of anti-theft performance, the thickness of a qualified anti-theft door is generally more than 20 mm. The interlayer of the door body should be reinforced with steel and filled with fillers to organically connect the front and back panels of the door body to enhance the door body. The overall strength.

However, anti-theft doors produced in small workshops often use iron sheets instead of steel plates, or low-quality inferior plates instead of steel plates, resulting in poor extension performance of anti-theft door shells and deformation due to external forces. Once the thieves forcibly use a crowbar and other equipment to destroy the door, the steel plate of the door can be deformed and finally lose the barrier function. The criminals often use some shortcomings of the anti-theft door, and the number of locking points is short. Open the lock, so that the door lock of the anti-theft door is opened silently, and finally achieve the purpose of stealing the door body and the door lock without damaging the door body.

The author visited several anti-theft door dealers, and they are also very worried about the current situation of the anti-theft door market. "Now anyone can make an anti-theft door. No matter if you are qualified or not, there are 500 anti-theft doors available on the market. "It is unqualified." Mr. Jia, a distributor of a brand of anti-theft doors, said, "The cost of an anti-theft door that meets national standards is 600 yuan, but the market is flooded with a large number of 400 and 500 low-quality anti-theft doors." Jia Mr. told the author that these inferior anti-theft doors will use the "steel door", "entry door", "protective door", "anti-pry door" and so on to deceive consumers.

Mr. Liu, the distributor of Wangli Security Doors, admitted to the author that because a large number of inferior security doors flooded the market, the quality of his products also declined. "I feel that the quality of security doors we make now is not as good as before. Why? Everyone? No one knows if you are doing fraud! "Mr. Liu told the author angrily," Wuhan people's character is cheap, but they still want to buy if they know it is parallel, which leads to no market for qualified anti-theft doors. "He reminded Consumers, "You might buy a low-quality security door for a few hundred dollars cheaper, but from a long-term perspective, you may lose more."

Why is the market flooded with inferior security doors?

The manufacturer has something to say

The staff of a well-known anti-theft door manufacturer told the author that the main reason why a large number of inferior anti-theft doors are now flooding the market is the high cost of anti-theft doors. "The price of steel plates in 2001 was 2000-3000 yuan / ton, but now it has risen to 6000 yuan / ton. In order to obtain high profits, some manufacturers have adopted cost reduction methods and reduced the use of steel plates, resulting in a large number of anti-theft doors with a thickness of only 0.5 mm, and even 0.4 and 0.3 mm, which cannot be burglar-proof at all. "

He said that in order to improve the current chaotic situation in the security door market, we must grasp at the source, "Who does not meet the standard, you will not be allowed to produce. Now the manufacturers found to have problems in the market, it will be fine to pay a fine, manufacturers continue Production, merchants continue to sell, is this not to harm the people? "He told the author, there are more unqualified products in the anti-theft door market in Wuhan than qualified ones, and the national standards are virtually useless, and the market is not well regulated.

It is reported that at the National Seminar on the Establishment of New Standards for Security Door Security held in Wuxi on November 28 last year, experts from three national security departments and leading domestic security door leading manufacturers jointly conducted the original standards for security door production. Re-revised, three new standards including "security door must be marked with a concave recess in the upper left corner" will be fully implemented this year.

In 1998, the state formulated the strong standard GB17565-1998 "General technical conditions for anti-theft security doors", which requires that the selection of materials for the production of anti-theft doors must meet the requirements of the standards, clearly stipulates that the thickness of the door frame should reach 2.0 mm or more, and specifies the anti-theft door lock points , Hinge parts, door leaf parts, and mandatory standards for door frame parts. This revision revised the original national standard, including the abnormal opening time of the anti-theft door is determined to be 30 minutes, 15 minutes, 10 minutes and 6 minutes; the length of the lock tongue protruding is not less than 16 mm; there are many locking points Wait at 8 o'clock. In view of the status of those who are under the banner of "entrance door" and "protection door" in the anti-theft door market and deceive consumers, the new standard stipulates that from this year, all anti-theft doors must be marked with a security level (A, A, (B, C, D, and S) The text of the anti-theft door is permanently fixed in the form of a Song gravure at the corner of the hinge, at a height of 1.60 meters from the ground, and a positive and negative error of 10 mm.

However, among the several anti-theft door dealers that the author visited, they were unaware of the new standard, and did not see any one of the dealers sell the anti-theft doors with new marks. In response, the author contacted Mr. Han, a staff member of the Wuhan Municipal Technical Supervision Bureau. He said that he was not very clear about the new standard and Wuhan did not implement such a standard.
