Background Overview

General Technical Requirements Standard for Vault Doors of Cultural Relics Storage Facilities, GB 37481-2019

The vault door of a cultural-relics storage facility is a specialized door installed at the entrance and exit of the facility, designed with a certain level of resistance to vandalism.

This standard for vault doors applies to the manufacturing, installation, inspection, and acceptance of vault door products in the cultural heritage and museum sector, the financial sector, the security industry, the industrial and commercial sectors, and related industries. Doors used in other cultural relic storage facilities and critical-item storage locations may be implemented by reference.

Lock accessories include: vault-door-specific locks, high-end combination locks, sand-gold combination locks, electronic fingerprint combination locks, fingerprint scanners, facial recognition systems, iris recognition systems, palm-vein scanners, time locks, smart controllers, scramble devices, and relocking mechanisms, among others.

Vault doors are classified into six levels—M, A, B, C, D, and E—based on their resistance to forced entry. Vault doors with waterproof and airtight sealing capabilities are designated by the letter S. Note: Levels D and E build upon traditional resistance to forced entry by additionally incorporating blast-resistant features.

Vault doors are classified according to their door leaf opening methods as single-leaf swing vault doors, double-leaf swing vault doors, and sliding vault doors, denoted by D, S, and Y, respectively. The corresponding secondary doors within these vault doors are designated as DZ, SZ, and YZ, respectively.

Vault Door Marking Method

The marking for a vault door consists of four components: the vault door name code, the opening method code, the protection level code (including waterproof and airtight functionality), and the enterprise-specific definition code. The marking method is as follows:

Common Features of Safe Door Products

The vault doors for Class A, B, and C stainless-steel cultural-relic storage facilities are designed and manufactured in accordance with the People’s Republic of China’s public-security industry standard GB 37481-2019, “General Technical Requirements for Vault Doors.”

The main body is fabricated from high-quality carbon steel plate, featuring an aesthetically pleasing appearance, a robust structure, and smooth operation. It also offers fire resistance, drill resistance, impact resistance, and flame-cutting resistance.

The door leaf is equipped with two exposed hinges and six fixed bolts on the hinge side, while the opening side features six bolts and each of the top and bottom sides has one steel adjustable bolt.

Optional accessories include an automatic jamming device, multi-lock interlock system, daily access gate, door-within-a-door configuration, heavy-duty locking mechanism, and waterproofing device.

The secondary door of the double-door system is installed below the main door and offers the same level of security.
