As the last line of defense for protecting valuables, the ability to resist violent destruction is the core value of double-leaf stainless steel vault door middle door. In the face of violent means such as prying, smashing, and cutting, this type of door needs to build a protection system from multiple dimensions such as material properties, structural design, lock protection, and detail reinforcement, so as to transform the anti-destruction ability of each link into an improvement in overall security.
The choice of materials is the foundation for resisting violent destruction. Stainless steel is the first choice for vault doors due to its high strength and corrosion resistance, but not all stainless steels have the same protective power. The stainless steel plate used in the vault door middle door must have a balance of high hardness and toughness, which can not only resist the impact of sharp tools, but also prevent brittle cracking caused by external impact. Special alloys or composite materials are also filled inside. These materials can not only increase the weight of the door body and increase the difficulty of violent prying, but also consume the cutting edge of the cutting tool through its own complex structure when it is cut, slowing down the cutting process.
The door body structure design of double-leaf stainless steel vault door middle door is the key line of defense against violence. The double-leaf design itself increases the difficulty of destruction, because the attacker needs to break through the protection of two doors at the same time. The door frame and the door panel adopt an integrated molding process to avoid weak points such as welding gaps and prevent violent breakthroughs from the interface. The bite part between the door frame and the door body will be designed into a multi-directional lock tongue structure. These lock tongues are deeply embedded in the groove of the door frame. Even if the door body is squeezed and deformed by external force, the lock tongue can still maintain a firmly locked state, making it difficult for attackers to enter by forcibly pushing or pulling the door body.
The protection performance of the lock system directly determines the safety of the door body. Double-leaf stainless steel vault door middle door is usually equipped with multiple locks, and mechanical locks and electronic locks cooperate with each other. The mechanical lock uses a complex gear and lever structure to prevent the insertion of violent unlocking tools; the electronic lock has an anti-pry alarm function, and once an abnormal external force is detected, the alarm system is immediately triggered. Some high-end locks also have an anti-drilling core design. Even if the lock core is attacked by a drill bit, the internal structure will automatically lock, making it impossible for attackers to open the door body by destroying the lock core. At the same time, the installation position and method of the lock are also specially designed, hidden in the key parts inside the door body to avoid direct exposure to violent attacks.
The reinforcement of connecting parts such as hinges and hinges cannot be ignored. If these parts are not strong enough, attackers may break the hinges to separate the door body from the door frame. The hinges of the vault door are made of high-strength alloy, and the connection with the door body and door frame is extremely strong. Some even adopt an embedded design to completely wrap the hinge inside the door body and door frame to prevent direct disassembly or damage by external forces. In addition, an anti-slip device will be set at the hinge. Even if the hinge is severely damaged, the door body cannot easily detach from the door frame and continue to play a protective role.
Sealing and buffering design also play an important role in resisting violence. The sealing strips on the edge of the door body are not only used for waterproofing and dustproofing, but also play a buffering role when subjected to violent impact, reducing the direct damage of the impact force to the door structure. At the same time, special buffer layers may be set inside the door body. When subjected to strong impact, these buffer layers absorb energy through their own deformation to prevent the door body from being irreversibly damaged due to excessive force, thereby maintaining the integrity and protection of the overall structure.
The coordination of alarm and monitoring systems is an important auxiliary to deal with violent destruction. The middle door of the vault door is usually connected to the surrounding security system. Once signs of violent destruction are detected, such as abnormal vibration and prying of the lock, the sound and light alarm will be triggered immediately, and the signal will be transmitted to the monitoring center. At the same time, the cameras installed around the door body will automatically focus and shoot, record the behavior and appearance characteristics of the attacker, and provide strong evidence for subsequent disposal. This combination of active and passive defense further enhances the ability of the middle door of the vault door to deal with violent destruction.
Daily maintenance and testing are necessary measures to ensure that the middle door of the vault door continues to maintain its anti-violence ability. Regularly check the structural integrity of the door body, test the operating status of the lock, and promptly discover and repair potential safety hazards. Maintain the stainless steel material on the surface of the door body to prevent strength loss due to corrosion. The anti-violence performance of the door body is simulated and tested with professional testing equipment to ensure that when facing real violent destruction, the double-leaf stainless steel vault door middle door can always uphold its protective duties and provide reliable security for the stored valuables.
