Lateral composite steel fire-proof and smoke-proof rolling curtain is another kind of novel fire-proof rolling curtain based on composite steel fire-proof rolling curtain. It is composed of axle cage box, push-out shaft, roll-in shaft, upper slide shaft, lower guide rail, barge wheel, motor (2 sets) and so on. Super-span, arc or multi-directional ultra-low space installation is the advantage of lateral composite fire-proof shutter. The product has good fire prevention, smoke prevention, heat insulation, anti-theft functions, and with the fire control center to implement linkage, while equipped with manual control and electric hoist. According to the standard of GB14102-9《 fire curtain, the fire resistance time is more than 3 hours, and its performance is up to the national inspection standard.
Suitable for large span, curved shape, low space fire compartmentation, such as the atrium, underground parking garage and other places.
1.The fire resistance: the fire resistance time is more than 180 min without loss of integrity, and the maximum thermal radiation strength is 0.45 w/cm, at 3 m of the backfire surface without loss of heat insulation. According to the judging condition of the backfire surface, the highest average temperature rise is 104.8 degrees, the highest single point temperature rise is 131.7 degrees, and the heat insulation is not lost. It can be used according to the grade fire proof shutter door, and the water mist spray device can be added.
2.Maximum size of single span：W≤35000mm. H≤5000mm.
3.Wind pressure resistance：Type 120 curtain B=3 m, midspan deflection ≤60 m.
4.Average noise: less than 60 dB.
