However, according to the author's observation on websites such as China consumer network, the complaints about the quality of anti-theft doors have not been reduced due to the promulgation of the general technical conditions for anti-theft doors. According to incomplete statistics, the complaints are mainly in the following aspects: first, the quality of anti-theft doors is unqualified; Second, no one came to repair after the repair; Third, shirking responsibility after causing losses; Fourth, the use of fire doors and other fake security doors. In fact, in the final analysis, it is the quality problem of the security door. The quality of anti-theft doors has been clearly stipulated in the general technical conditions for anti-theft safety doors. Consumers can open their eyes to these four 'standards' when purchasing:

first, the grade is based on the length of anti damage time, plate thickness and other indicators. In the new standard, the anti-theft security level of anti-theft door products is re divided, and the anti-theft security level is adjusted to 'a', 'B', 'C' and'd '. A is the highest level, and it decreases accordingly. The anti damage time of the anti-theft door also decreases step by step, and the lowest level D is at least 6 minutes

thickness of steel plate of second door leaf. Grades A, B, C and D should reach 2mm, 2mm, 1.8mm and 1.5mm respectively. The thickness of steel plate is directly related to the security performance of anti-theft door

three look lock. According to the provisions of the new standard, the lock of the anti-theft door should be able to open the door leaf within the anti damage time, even if the lock cylinder is drilled out, the lock body connector is pried off to disassemble the lock, or the prizing tool is extended through the upper and lower gap, and the lock tongue is loosened; The locking points between the door frame and the door leaf shall be no less than 12, 10, 8 and 6 respectively according to the anti-theft security levels a, B, C and D; The effective length of the main latch of the anti-theft door shall not be less than 16mm, and there shall be a latch stop device

four look at the mark. The new standard also adds content that can help consumers identify the authenticity of anti-theft doors, which requires that anti-theft doors should have permanent fixed marks. The anti-theft door mark consists of three parts. The mark symbols are Pinyin letters. From left to right, they are anti-theft safety door code (FAM), anti-theft security level and enterprise custom features (including enterprise code and product code). Among them, the anti-theft security level mark is permanently fixed at a position about 160 cm above the ground on the edge of the inner hinge. While 'metal doors',' steel doors' and 'entry doors' are not anti-theft doors. Consumers should pay attention to sharpening their eyes and not be deceived by merchants when purchasing
