As the heart of the security door, its quality is the top priority of the security door. Some security doors use ultra-thick multifunctional anti-theft locks, and the thickness of locking tongue is thicker than that of ordinary locks 1/2. Emergency opening can be started indoors and outdoors without a key, which makes users safer and more convenient. As far as the side lock is concerned, a new type of side lock with hook is adopted. When closing the door, the lock tongue locks the door frame, and the new side lock is thickened, widened and lengthened, which is more resistant to prying. The three-layer anti-edge-picking engagement structure, coupled with the multi-directional locking mechanism, makes the door leaf and door frame integrated in the locked state, so that thieves can't start. In short, the lock core is the key to the security door. I suggest you pay attention to the choice of lock core when buying security doors. Door leaf: the door leaf of special keel storm-proof security door is mainly to prevent people from violent attacks and prying open. In general, the keel of the door leaf of the security door is welded by door frames of various shapes and structures, which not only ensures no deformation, but also prevents its damage by storm. All locks are reinforced with 3 mm thick steel plates to prevent them from drilling in and damaging the locks. The thickness of the door leaf has increased from 40 mm to 68 mm and 88 mm now, which improves the impact resistance. In a word, the anti-theft performance of an excellent anti-theft door is determined by its lock core and door leaf. We should not only pay attention to its material, but also pay attention to its production technology and design. If you need to choose a security door, you can't be careless.
