The anti-tailgating interlocking security door, also known as an interlock access control door, is a security entrance system specially designed for confidential areas and key security zones. It is widely used in archive rooms, confidential offices, bank branches, government service halls, equipment rooms, and secure facilities. Through a dual-door interlocking mechanism, the system helps prevent unauthorized tailgating entry, standardizes access procedures, and improves overall security management.

Structural Features

1. The door adopts a dual-door independent interlocking structure. The inner and outer doors work with an interlock control system. When one door is opened, the other door remains automatically locked and cannot be opened at the same time.

2. The door frame and door leaf are manufactured from thickened steel materials with integrated welding forming. The overall structure is solid with good impact resistance.

3. The door is equipped with a dedicated electronic interlocking lock system. Electrical signals operate reliably, with stable response and accurate interlocking logic.

4. The door frame is fitted with embedded sealing strips. After closing, the door provides tight fitting performance with basic functions including dust resistance, sound reduction, and wind protection.

5. The entire system adopts a modular assembly structure with standardized components, making on-site installation convenient and later maintenance easier.

6. The door supports multiple installation methods including embedded installation and post-installation mounting, making it suitable for both new projects and renovation applications.

Safety Features

1. The dual-door interlocking logic strictly controls access procedures, helping prevent tailgating and forced entry while maintaining orderly passage management.

2. Equipped with an emergency unlocking device, allowing manual unlocking during power failure or emergency situations to meet access requirements.

3. The lock system adopts an anti-prying structure design with secure locking engagement, helping reduce unauthorized opening risks caused by external force.

4. Supports integration with multiple verification methods including access cards, passwords, and facial recognition systems for clear permission management.

5. The system includes door status monitoring functions, allowing security systems to identify door opening and closing conditions for coordinated management.

Humanized Design

1. The door opening and closing process is optimized with suitable damping control, providing smooth operation without jamming during daily use.

2. The system can be integrated with access record management systems to store entry and exit information for daily inspection and security tracking.

3. Optional observation windows are available, allowing users to view indoor and outdoor conditions before passage and improving access safety.

4. The equipment is designed for frequent access environments, with durable mechanical and electronic structures suitable for continuous operation.

5. The overall appearance is simple and neat, matching the interior styles of government, office, and confidential facilities.

Surface Coating Process

The steel plates of the door body undergo multiple pre-treatment processes, including degreasing, rust removal, and phosphating, to remove surface impurities and oxidation layers while improving base material stability.

The surface adopts an electrostatic powder coating process with high-temperature curing. The coating is smooth and uniform with strong adhesion, providing scratch resistance, wear resistance, and stable protection against rust and corrosion. It is suitable for long-term indoor applications.

Dimensions and Specifications

1. Standard single door size: Height 2050mm × Width 950mm. The system is installed as a complete dual-door set and can be customized according to actual doorway dimensions.

2. The door leaf is manufactured from thickened cold-rolled steel plates with uniform thickness and high surface flatness.

3. The door frame adopts integrated bending forming technology, providing a neat structure and accurate fitting clearance with the door leaf.

4. The interlocking control board adopts an integrated design with organized wiring, strong anti-interference capability, and stable operation.

5. Equipped with high-quality dedicated hinges, providing strong load-bearing capacity, smooth opening and closing, and reduced risk of deformation or sagging during long-term use.

6. Optional accessories include tempered glass viewing windows, door closers, integrated access control terminals, fingerprint readers, and other functional components.

7. The product complies with general security access control equipment manufacturing standards and is suitable for confidential areas, security zones, and other controlled access environments.
