The Development History of the Bank Vault Door!

Updated: Jun 28

Bank vault door is ambiguous to the ordinary people.Why?Because it often appears in the movies and it is not well-konwn by the public. let's find out the history of the bank vault door.


The main function of the bank vault door is to keep the safety of valuables. With the rapid growth of social wealth brought about by economic development in the past few decades, vault doors have gradually appeared in more and more places, and the market scale has become larger and larger. According to the data analysis of the 2020-2025 global bank vault door market survey report released by authoritative research institutions: the global vault door market has continued to grow in recent years. In 2019, the global bank vault door market reached 20 billion yuan, and it will continue to be 5 years per year for the next 5 years. %-10% growth rate.


The main market of bank vault door for sale is in North America, followed by Asia Pacific, Middle East, and Europe. In 2019, China's vault door market is about 300 million yuan, ranking behind the United States, Canada, Mexico, and Australia. The top few countries are all in poor public security, or there are more catastrophic climates such as tornadoes. Individual users install and use vault doors in their homes to protect property and personal safety. While the public security of China is in good condition. Only certain institutions and government departments such as banks, military, museums, etc. use vault doors. Therfore,the China market for individual users has a huge potentiality, and needs further development.


Before the advent of bank vault doors, people usually used safes to store valuables. However, safes have inherent shortcomings, such as small capacity, lightweight, and low-security performance, which cannot meet people's storage needs for large capacity and high-security performance! The vault door developed from the anti-theft door solves these series of problems very well.


The most primitive vault door has a relatively simple structure, usually using a thicker steel plate and multiple door bolts as the main body of protection. At the beginning of the 20th century, this protective performance was sufficient, but with the advent of high-performance explosives and oxygen-acetylene cutting torches, the protective performance of such a vault door was obviously insufficient! The first is explosives. People use tools to pry the cracks in the door, open a gap, insert explosives and detonate, and then explode the vault door, or use a large number of explosives to force the door open. The second is the oxygen-acetylene cutting torch, which exceeds 3300 degrees. At high temperatures, you can quickly cut the steel plate of the vault door! With the emergence of these new materials and new tools, bank vault door

manufacturers have to upgrade their products, improve the structure and materials of the vault door in several aspects, and strengthen the protective performance of the bank vault door:


(1) At the position where the door frame and the door leaf are combined, a stepped groove is made to close, so that the tool cannot be directly inserted into the door gap and prevent the gap from being pried;


(2) In the protective layer, add high-strength concrete and cast iron, and other high-temperature materials to prevent it from being easily cut by the oxygen-acetylene cutting torch;


(3) Multiple solid reinforced door bolts are equipped around the door leaf to resist strong damage caused by explosives or other large equipment;


(4) Design a combination lock structure, install 2-3 locks on the door leaf, and separate different locks for management. When opening the door, 2-3 managers must be present at the same time to open the vault door. At the same time, install a time lock on the inside of the door to ensure that the vault door can only be opened within a certain period of time, effectively preventing criminals from coercing managers to open the vault door for robbery;


(5) Design a heavy lock structure and install it on weak parts such as vault door locks. When criminals destroy the weakness of the vault door, the relocking structure will automatically activate and lock the vault door from the inside, so that even if the criminals break through the weak point, they cannot open the round bank vault door.
