Due to the poor quality of anti-theft doors installed by some community developers when they delivered their homes, some homeowners and some owners who are engaged in second-hand housing renovations have the need to replace security doors. But does it really need to replace the security door? What kind of security door performance is higher? Most owners feel out of mind. We interviewed relevant experts and experts suggested that for the sake of insurance, owners with a tenancy of more than ten years and developers unable to provide test reports are advised to replace security doors. In the purchase, the owner should guard against traps such as entrance doors and armor doors.

The old house is best replaced as a whole
According to Ma Mingyu, an engineer of the Ministry of Public Security’s Ministry of Public Security’s Security and Police Electronic Product Quality Testing Center, many old residential security doors are casually installed with an ordinary iron or steel door in front of a wooden door. Strictly speaking, these The door cannot be called a security door, and some communities do not even have iron gates. With the increase of social mobility, and most of the property management of the old community is not very in place, the security door in the home can not meet the needs of the general anti-theft, it is recommended that owners aged over 10 years replace the security door as a whole.
There is no need to replace the anti-theft door in the newly built community, just replace the lock. However, Ma Mingyu said that due to the lack of corresponding understanding of some security developers on anti-theft doors, the anti-theft awareness is not high, and the anti-theft door may be unqualified. The landlord is required to request the developer to provide a security door detection report when handing in the room. If it is not possible to provide it, it is better to consider replacing the security door as a whole during the renovation.
More than four security doors are of good quality
What kind of anti-theft door is best? Ma Mingyu introduced that the security door is divided into steel, Stainless Steel, steel wood, Copper or other composite materials. Among them, steel and steel wood security doors are the most common. The structure of the steel security door includes the outer panel (that is, the panel that stands outside the door) and the inner panel (the panel that stands inside the door). In the middle is a layer of steel skeleton. A good steel anti-theft door skeleton is filled with materials such as asbestos, which has the functions of fire prevention, heat preservation and sound insulation. Steel wood security doors have the same structure as steel security doors except that a layer of wood veneers is added on the surface.
According to the different anti-vandalism performance, China's anti-theft door mandatory standards - "General technical conditions for anti-theft security doors," from high to low security door is divided into A, B, C, D four security levels, and the provisions of the business must be in theft The hinges on the inside of the door are marked with Chinese characters in a prominent position about 160 cm above the ground, indicating their safety level. In addition, the thickness of the door frame and the panel thickness of the door leaf must also meet the corresponding requirements. The owner can remove the cat's eyes and doorbells to judge whether the thickness of the door frame and the thickness of the door panel meet the national mandatory standards.
