Basic parameters of the military armory door:

Clear passage (width × height): 900×2000, 1000×2000, 1100×2100

Level M A B C

Anti-vandalism limit (min) 15 30 60 120

Fire-resistance rating: 1.5, 2, 4, 6

The gap around the front perimeter of the door frame and door leaf shall not exceed 1 mm, and there shall be no gaps through which the interior of the door can be directly viewed.

The surfaces of the door frame and door leaf shall be smooth, with a flatness tolerance of no more than 2 mm for the exterior surface and no more than 4 mm for the interior surface.

Performance characteristics of the military armory door:

1. Anti-vandalism: Even after subjected to destructive methods such as prying with manual tools like hammers, sledgehammers, and hacksaws, as well as electric grinding, drilling with electric drills, and oxyacetylene flame cutting, the gun storage door remains securely closed and operational.

2. Fire resistance: When the vault is exposed to a fire involving both the building and an oil-based fuel mixture, with temperatures reaching 1,000°C, the vault door must still be able to open normally after cooling to ambient temperature.

3. Corrosion-resistant performance: The gun vault door is manufactured using advanced anti-corrosion protection processes, such as baked enamel coating, providing robust corrosion resistance even when installed in damp, poorly ventilated environments like underground vaults.

4. Heavy-duty door hinge with lightweight bearing assembly, enabling smooth and effortless 180-degree opening.

5. An imported combination lock with 100 million possible combinations, certified by U.L., offering precision and reliability.

6. Equipped with an automatic relocking mechanism that prevents forced breakage.
