The Double-Track Dual-Curtain Inorganic Fabric Fire Shutter is a fire-rated inorganic fabric shutter system designed for large building openings requiring fire compartmentation and thermal separation.
Unlike a conventional single-curtain fire shutter, this system uses two independent inorganic fire-resistant curtain assemblies within a double-track structure. The separated curtains descend vertically to close the protected opening and help restrict flame spread, high-temperature gases and heat transfer between fire compartments.
Manufactured by Huadun Door Industry, a professional inorganic fabric fire shutter manufacturer and OEM supplier, the system integrates fire-resistant curtains, double steel guide tracks, roller assemblies, a dedicated fire shutter motor and fire control components into a complete fire protection solution.
Huadun provides custom double-track fire shutters and OEM fire compartmentation solutions for commercial, industrial and public building projects.

Large fire compartment openings can be difficult to protect with conventional hinged fire doors or standard fire shutters, particularly where a wide opening requires reliable automatic fire separation.
The Double-Track Dual-Curtain Inorganic Fabric Fire Shutter uses two separate flexible fire-resistant curtains running within parallel guide tracks. Unlike a folding fire shutter, the curtains are wound onto upper roller assemblies during normal operation and descend vertically when deployed.
The dual-curtain arrangement creates a separated barrier system designed to improve thermal separation across the protected opening. The curtain assemblies use multi-layer inorganic fire-resistant materials selected according to the required project performance and tested system configuration.
A dedicated fire shutter motor and control panel manage the opening and emergency closing sequence. The control system can interface with the building fire alarm system to automatically deploy the curtains when the specified fire signal is received.
Huadun manufactures each custom fire shutter according to opening dimensions, structural conditions, installation space and project fire protection requirements, providing OEM production and engineering support for international customers.
Two independent fire-resistant curtain assemblies operate within parallel guide tracks, creating a separated dual-curtain fire barrier for fire compartmentation applications.
The flexible curtains use inorganic fire-resistant textile and insulation materials designed for high-temperature fire protection applications. Final material composition and fire performance should correspond to the tested system configuration.
The curtains are wound onto upper roller assemblies during normal operation and descend vertically along their respective tracks during emergency deployment.
This rolling mechanism distinguishes the product from Huadun's Double-Track Dual-Curtain Inorganic Fabric Folding Fire Shutter, which uses a folding-lift storage system.
A dedicated fire shutter motor and control system provide automatic emergency deployment. The system is designed primarily for fire compartmentation and emergency closing, rather than high-frequency daily access.
The control panel can interface with the building fire alarm system. When the specified fire signal is received, the system initiates the emergency closing sequence and both curtains descend to the designated position.
The system is suitable for large fire-rated openings in commercial, industrial and public buildings where automatic fire separation is required.
The system can be engineered according to:
● Opening width and height
● Structural installation conditions
● Double-track arrangement
● Curtain separation
● Roller and shaft configuration
● Fire motor selection
● Control requirements
● Available headroom and side room
Huadun can manufacture the complete custom fire shutter system according to:
Huadun provides custom fire shutter and OEM manufacturing according to project dimensions, installation conditions and fire protection requirements, allowing the system to be adapted to different building layouts.

● Two inorganic fire-resistant curtain assemblies
● Double steel guide tracks
● Roller / shaft assemblies
● Bottom rails
● Mounting brackets
● Dedicated fire shutter motor
● Fire shutter control panel
● Fire alarm interface
● Protective hood / head box where required
The product uses a dual-curtain rolling mechanism.
During normal building operation, the two curtain assemblies are wound around the roller system above the opening, leaving the protected passage clear.

1.The building fire alarm system generates the specified fire signal;
2.The fire shutter control panel receives the signal;
3.The dedicated fire shutter drive system initiates the emergency closing sequence;
4.Both inorganic curtain assemblies unwind from the upper roller system;
5.Each curtain descends vertically through its corresponding guide track;
6.The bottom rails reach the designed closing position;
7.The two separated curtains create a complete dual-barrier fire compartmentation system.
The principal purpose of the system is to close the protected opening, restrict fire spread and reduce heat transfer between adjacent building compartments.

It is an automatic fire shutter system using two separate inorganic fire-resistant curtain assemblies running in parallel double guide tracks.
The two-curtain arrangement provides a separated fire barrier system designed for fire compartmentation and improved thermal protection across building openings.
A double-layer curtain may refer to two material layers combined into one curtain. In this system, Dual-Curtain means two separate curtain assemblies installed on two guide tracks with a designed separation between them.
This product uses a vertical rolling mechanism. The curtains are wound onto upper roller assemblies.
A folding fire shutter uses a folding-lift mechanism to stack the curtains beneath the upper structure. The two systems are designed for different installation and storage requirements.
Yes. The fire shutter control system can be configured to receive the required building fire alarm signal and initiate the automatic emergency closing sequence.
Yes. Huadun manufactures the system according to opening width, height, structural conditions, installation space, curtain configuration and fire-control requirements.
