Our premium double-track, double-curtain inorganic fire rated roller shutter is light and insulates well. The reverse-side temperature stays low, and its fire resistance is complete. That makes it a good fit for very large spans and unusual fire-compartment shapes, and it puts less load on the building structure.
Fire Rated Rolling Shutter Door Specifications
- Average temperature rise on the unexposed side: ≤ 79.6°C. Single-point rise: ≤ 113.3°C.
- Fire resistance rating: 4.0 hours or more.
- Opening and closing speed: 2–9 m/min.
- Smoke leakage: no more than 0.2 m³/(m²·min).
Fire Rated Roller Shutter Parameters
- Fire performance: holds back fire for 3.0 hours (180 min). Radiation heat on the unexposed side: 0.61 W/cm².
- Wind-pressure resistance: at 784.5 Pa, mid-curtain deflection is 45 mm.
- Motor power: 0.25–1.5 kW.
- Main power: AC380V 50Hz. Control power: DC12–24V.
- Average opening/closing speed: 2–9 m/min. Gravity descent speed: 4–9 m/min.
Control Method
The electric control system takes on/off signals from smoke and heat detectors to close the door, or it links to the fire control center. In normal use you can run the door by hand. In a fire it drops to the midpoint on its own, then continues to the bottom after a delay. During a fire you can press any key to send the door back up. The reverse height and the midpoint dwell time are both adjustable. On request we add an obstacle-stop safety sensor and a low-temperature (70°C) thermal-fuse device.
Fire Rated Roller Shutter Classifications
- Steel fire rated roller shutter: curtain, rails, bottom bar, lintel, and housing are steel, with a roller motor and control box, meeting fire-integrity requirements.
- Inorganic composite fire rated roller shutter: curtain of inorganic fiber, with steel clamps, rails, bottom bar, lintel, and housing, plus roller motor and control box, meeting fire-integrity requirements.
- Premium fire rated roller shutter: curtain of steel or inorganic fiber, with steel rails, bottom bar, clamps, lintel, and housing, plus roller motor and control box, meeting fire-integrity, insulation, and smoke-control requirements.
