The irreplaceable role of bulletproof steel plates in bank vaults

Bank vaults are the last line of defense for financial security, and bulletproof steel plates, with their unparalleled penetration resistance, are a core barrier. Their multi-layered composite structure can withstand continuous fire from 7.62mm rifle rounds, while ordinary security doors can only withstand single impacts from pistol rounds. In an attempted burglary at a bank in Shenzhen, the robbers spent seven hours cutting only 5 centimeters of the door panel, demonstrating the absolute effectiveness of bulletproof steel plates against violent intrusion.

In terms of material, bulletproof steel plates utilize a composite process of 304 stainless steel and Kevlar fiber, offering both corrosion resistance and energy absorption properties, far exceeding the protection provided by ordinary steel plates. Financial-grade vault doors are even certified to the GA/T143-2019 national standard, ensuring asset security in even the most extreme environments with their explosion and fireproof properties.

While smart locks can enhance security, without the physical defenses of bulletproof steel plates, any electronic system can be compromised. This collaborative model of "hardware as shield and software as spear" has established the irreplaceable position of bulletproof steel plates in financial security.
