Second, the purchase skills of security doors
1. Inspection of process quality: Pay special attention to check whether there are welding defects, such as open welding, incomplete welding and missing welding. See whether the door leaf and door frame are closely matched, whether the gap is uniform, whether the opening is flexible and whether the joints are tight. The surface of the door panel should be treated with anti-corrosion, and generally it should be painted and sprayed with plastic. The surface of the paint layer should be free of bubbles and uniform in color. Most doors are also embedded with rubber sealing strips on the door frames, so there will be no harsh metal collision when closing the door.
2. Lock inspection: generally qualified security doors use special anti-theft locks that have passed the inspection by the public security department, and at the same time, they should be protected by steel plates with a thickness of more than 3.0 mm Now many special anti-theft locks are multi-directional locks, which have the advantage that not only the door locks are locked, but also the upper and lower rails can be inserted to lock the doors. The prying resistance of the door is greatly improved.
3. The anti-sabotage function is the most important function of the security door. At the time of purchase, the seller may be required to show the inspection certificate of relevant departments, and the product quality shall meet the technical requirements of the national standard GB 17565- 1998 "General Technical Conditions for Anti-theft Safety Doors".
