Composite Steel Fire Shutter

1. System Overview

The Steel Fire Shutter is a building fire protection assembly that integrates fire compartmentation and smoke control functions. It consists of a composite steel curtain, guide rails, a roller shaft, and related operating components.
In the event of a fire, the shutter descends automatically or manually to form a reliable fire-resistant barrier between fire compartments, effectively preventing the spread of flames and high-temperature smoke.

Based on conventional steel fire shutters, the composite type incorporates thermal insulation and smoke containment designs, combining high structural strength with enhanced fire integrity performance. It is widely used in fire separation systems of commercial and public buildings in accordance with modern fire safety requirements.

2. Key Advantages

1. Steel construction with high strength and durability
Manufactured with high-quality composite steel curtain panels and metal components, the shutter offers robust structural strength and stable long-term performance, suitable for frequent operation and large-span openings.

2. Composite design combining fire resistance and thermal insulation
The curtain incorporates an internal fire-resistive insulation layer, effectively limiting flame spread while reducing temperature rise on the unexposed (cold) side, thereby enhancing compartment safety.

3. Reliable smoke containment performance
Through optimized curtain structure and sealed guide rails, smoke leakage is minimized. When used in conjunction with smoke compartments and smoke exhaust systems, overall smoke control efficiency is significantly improved.

4. Automatic interlocking with fast response
The system can be interfaced with the fire alarm system to automatically descend upon fire detection, while also supporting manual control to ensure reliable operation under emergency conditions.

5. Adaptable to various building configurations
Customizable according to opening dimensions and spatial constraints, making it suitable for large commercial spaces, underground facilities, and public buildings.

3. Operating Principle

1. Under normal conditions, the fire shutter remains rolled up on the roller shaft in the open position, allowing unobstructed access and space utilization.

2. When a fire occurs, the fire alarm system sends a control signal.

3. The shutter control unit is activated, and the composite steel fire shutter descends automatically at a preset speed.

4. Once fully closed, the shutter forms a continuous and stable fire barrier between fire compartments.

5. After the fire event and upon confirmation of safety, the shutter can be reset manually.
