Many consumers buy the security door, because the function and product attributes of the security door are not well understood. In most cases, the selection of the security door is mainly based on the manufacturer's introduction. However, the selection of the security door is flawed. Below, the search network has compiled some methods for selecting security doors, hoping to help the consumers.
First of all: understand whether the quality of the security door is passed.
The anti-vandal function is the most important function of anti-theft security. At the time of purchase, the seller can be required to present the quality inspection report of the relevant department. Remind that the product quality should meet the technical requirements of the national standard GBl7565-1998 "General technical conditions for anti-theft security doors". The inspection of the quality inspection report is the first step in purchasing a security door.
Second: observe whether the thickness of the steel plate is up to standard
The thickness of the steel plate of the security door frame is not less than 2mm, and the thickness of the steel plate on the front and rear sides of the door leaf is generally between 0.8mm and 1.2ram. The door and the reinforcing plate are arranged inside the door leaf. The thickness of the steel plate of the inspection door frame can be known by observing the keyhole on the door frame. For the observation of the thickness of the door leaf plate, the consumer can remove the cat's eye of the security door and view its thickness from the cat's eye hole. Since the difference in thickness of the steel plate is often the difference in millimeters, it is difficult to accurately grasp the visual inspection. At this time, the consumer can preferably use the vernier caliper (professional macro measurement tool) for detection. Remind that the thickness of the door frame steel plate of some unqualified products on the market is often only 1.6mm to 1.7mm, less than 2mm. There are also some unsatisfactory household door leaf steel plates with a thickness of 0.6mm pretending to be 0.8mm thick, or with a 0.8mm pretending lmm door to sell, deceiving consumers.
Again: check if the lock is qualified
The security door with the lock is generally three-position lock or five-position lock. Not only the door lock is locked, but also the upper and lower rails can be inserted and locked to fix the door. According to the national standards, the standard for anti-theft security door locks is to have a welded and strengthened protective steel plate within a radius of 100 ram from the center of the keyhole. It is reminded that some manufacturers have no strengthening measures at all, or only a small piece of thin iron sheet is used as a reinforcing steel plate. The strength and size cannot achieve the effect of strengthening the steel plate. Consumers should check carefully when purchasing.
