Steel Class-A Fire-Resistant Roller Shutter (Water Mist Composite Type)

Scope of Application

Large shopping malls, exhibition halls, high-speed rail stations, hotels, hospitals, and underground parking garages

Key Features

1. Directly utilizing the water supply from the building’s fire protection system effectively reduces construction complexity and lowers production costs.

2. The temperature-sensing device of the water mist system can automatically control the water mist sprinkler system, ensuring that the system remains operational at all times.

3. The thermal-sensing deluge valve can replace the solenoid valve for controlling the water supply system, thereby ensuring system safety.

Technical Indicators

1. The fire-resistance rating exceeds 240 minutes, with an average temperature rise on the unexposed surface of 92.3°C and a maximum single-point temperature rise of 118.3°C.

2. The water supply pressure is 0.15 MPa, the average water distribution intensity is 0.14 m³/h·m², and the spray angle of the nozzles is 90°.

4. The spacing between adjacent sprinklers is 300 mm, and the horizontal distance from each sprinkler to the curtain panel is 450 mm.

5. After adjacent interlocking curtain panels are connected in series, they shall remain securely engaged when swung through ±90°.

6. Opening/closing operating speed: 2 m/min–7.5 m/min; self-weight descent speed not exceeding 9.5 m/min.
