The vault door is divided into four levels, which are M level, A level, B level, and C level. The performance represented by different levels is also different.
M level: This is the worst of the four levels, its plate thickness is 7MM, the lock is the use of domestic mechanical locks with double locks, due to the existence of defects in the thickness of the steel plate, can not reach the * Department of the test, so many Enterprises do not produce this level.
Grade A: Grade A is the most widely used grade. It has a plate thickness of 8mm. The lock adopts a domestic fine mechanical lock with a double head lock. The price is low and the performance is very high. It is the most cost-effective level.
Class B: Class B vault door is even better, it has a plate thickness of 10MM, the lock is very safe and reliable with the United States Shajin lock with a domestic shackles, like jewelry stores, museums are usually used this level of doors.
Grade C and Grade C are the highest. They are composed of 12mm thick steel plate and American sand gold locks and shackles. The fire resistance is up to 4 hours, and the anti-riot capability is also 2 hours. The application of this level of doors in the bank is compared. Big. 
In fact, the purchase of the vault doors is also relatively simple, and consumers can only purchase high-quality products with some understanding of the products.

1. Chassis of the spreader features strong carrying capability, low oil consumption, and easy operation
2. Patented hydraulic servo technology provides powerful driving force for the system
3. The asphalt spreading machine employs intelligent control system, radar speed tester, monitor, and both automatic and manual operation system. Only one driver is needed to accomplish the distribution job
4. Pipes for carrying bitumen are coated with heat transfer oil to ensure that all of the machine parts run smoothly and don't have to be cleaned
5. The 3 anti-collision foldable sprinkler heads are of high precision and uniformity
6. The imported pump for high-viscosity asphalt meets various working conditions
7. A unique aggregate feeding and distribution system ensures the materials are sprayed uniformly, consecutively and stably
8. Different spray nozzles are controlled independently and can work jointly with each other freely
9. HD camera is equipped at back of the equipment for effective monitor and control
10. The patented bitumen tank with large volume can be heated in a short time and works to maintain the temperature of the materials. Stability of the bitumen is largely improved by the mixing device
How to distinguish the quality of the vault doors
Nowadays, the application scope of the vault door is also becoming wider and wider. It can be used from banks to museums, gold stores, and villas. This is better for the majority of consumers and it will help us do a good job of protection. For the performance of the product we should be more understanding, but for the product's material, protection level and other aspects of the do not understand when it is easy to fall into the trap of some manufacturers, then we should choose how to distinguish the quality of the product ?
