Anti-theft doors are designed to guard against burglars. If poor security doors are used, not only will the family property suffer losses, but the owner may be locked up inside or outside the house. The "12365" hotline of the Beijing Municipal Bureau of Quality and Technical Supervision received 22 complaints about anti-theft doors on a monthly basis, accounting for 4% of the total number of complaints. Most of them reflect the fact that the door locks cannot be used normally, instead of locking people at home or returning. Home can not open the door lock.
According to relevant standards, the security level of security doors can be divided into A-level, B-level and C-level, among which C-level anti-theft performance is the highest, B-level second, and A-level general.

The locks used on the door body are anti-theft locks. In addition, the surface of the door panel should be treated with anti-corrosion treatment. Generally, it is painted and sprayed. The surface of the paint layer should be free from bubbles and uniform in color. The weight of the door is generally more than 40 kg. The door and the door frame have more than three fixed holes. Most of the doors A rubber sealing strip is also embedded in the door frame, and no harsh metallic impact sound is emitted when the door is closed.
When consumers purchase anti-theft doors in the market, they should generally choose brand security doors with large-scale enterprises. The reputation of these products is relatively good and the after-sales service is more standardized. When purchasing, you should also pay attention to the “FAM†logo, company name, and implementation standards of the security door. The doors that meet the standards can be safe and reliable.
Finished door quality is difficult to guarantee
In home decoration, the door must be remodeled and updated, and most of the updates are selected. There are two options for the door: One is to choose the finished door, and the other is to use the self-made door with a big core board.
Finished doors are often molded doors, solid wood doors and solid wood doors. The molded door is beautiful in shape and is not easy to be deformed compared to the solid wood door. The price is only 200-300 yuan, which is a low-grade decoration. The solid wood molding door is moderately priced and has the appearance of a solid wood door, so it is generally welcomed, but its quality and appearance are not as good as those of a solid wood door. There are also defects in the solid wood door that are easily deformed and cracked. Since the molded door is made by pressing two fiberboards, the fiberboard contains a certain amount of formaldehyde, and the firmness of its doors is poor, which leads to a downward trend in sales of molded doors. With the gradual emphasis on the environmental issues of decoration, solid wood doors and solid wood model doors are naturally the first choice for decoration.
The “12365†hotline of the Beijing Municipal Bureau of Quality and Technical Supervision received 22 complaints about finished products doors, accounting for 4% of the total, which mostly reflected the deformation of the door body, cracking, lifting of the epidermis, and installation of doors and door covers. Qualified and so on. At present, in some non-standard building materials markets, the quality of finished products sold is difficult to guarantee. The moisture content of the wood exceeds the standard or the drying process is not standardized, causing the door to be deformed or cracked within a short period of time after installation. In addition, some dealers use solid wood molding doors to impersonate solid wood doors or use low-grade materials as high-grade solid wood doors.
Plastic steel doors and windows more than counterfeit
The market for steel doors and windows is uneven, and consumers will leave a lot of hidden dangers once they have installed inferior products. The “12365†hotline of the Beijing Municipal Bureau of Quality and Technical Supervision received 18 complaints about doors and windows on the hotline in the month, accounting for 3% of the total amount, mostly reflecting the serious deformation of the doors and windows, pushing and pulling, leakage of rain, ventilation, poor quality window screening, hardware Things are not good and so on.
Plastic steel doors and windows, like other building materials, have high, medium, and low grades. Plastic steel doors and windows should use UPVC profiles. UPVC profile is a decisive factor in the quality and grade of plastic steel doors and windows. Secondly, the hardware selected for doors and windows is made of metal as far as possible, and its inherent strength, appearance and usability directly affect the performance of doors and windows. In addition, UPVC profiles must be provided with steel linings that conform to the thickness, otherwise they cannot be called “plastic steelâ€. Doors and windows. There are many plastic steel fittings used in middle and low-grade plastic steel doors and windows. There are hidden dangers in their quality and longevity. There are no steel linings in the doors or windows, or steel sheets are imbedded in the steel. The assembly cannot guarantee the overall quality of the doors and windows. Therefore, before selecting a certain brand of plastic steel doors and windows, you can first obtain a test report of plastic materials from the seller, and check its four main indicators, namely, hardness, low temperature drop impact test, high and low temperature dimensional change rate, and angular strength test. Meet the requirements. The above four indicators can reflect the product quality of steel doors and windows, but also be alert to counterfeit OEM products, in addition to checking whether the processing or assembly according to the standard or contract, the doors and windows offer too low to be a good inspection.
