Fire rated roller shutter doors go into public spaces that carry fire-safety requirements: large supermarkets, shopping malls, material markets, exhibition halls, factories, warehouses, and underground parking garages. When a fire alarm sounds, the shutter drops on its own under the building’s fire control system, following a preset program. That slows the spread of flames to other areas and buys time for firefighting. These doors are built to a higher standard — the whole system has to survive around 1,100°C for a set period. How long the door holds its rating is the spec that matters most.
Fire Rated Roller Shutter Applications
Where you put the door shapes the spec you need. A supermarket loading bay takes a different curtain than an underground garage stairwell. In each case the shutter works the same way: the alarm triggers it, the fire control system runs the descent program, and the opening is sealed long enough for people to evacuate and for crews to respond. Match the curtain material and speed to the space, and the door does its job without fuss.
Main Parameters
Door surface: the housing is cold-rolled steel plate, 2.0–2.5 mm thick.
Curtain materials:
- High-density industrial base fabric, made in France, 0.8–2.0 mm thick. Tensile strength (warp/weft): 5700 / 5100 N per 5 cm. Tear strength (warp/weft): 900 / 80 N. Operating temperature −30°C to +70°C. Flame classification NF-P92-503 M2 (France) or DIN 4102 B1 (Germany).
- Transparent PVC sheet, 1.5–2.0 mm thick.
- Control system: PLC and frequency converter.
- Manual and automatic controls: push button, pull cord, remote, magnetic loop, radar, and photo-eye interlock, so the door opens and closes the way your site needs.
Types of Fire Rated Roller Shutters
You will see a few types of fire rated roller shutters built around the curtain. The fabric curtain suits spaces that need insulation and a low reverse-side temperature. The transparent PVC curtain keeps visibility at a service opening. Steel and inorganic composite curtains trade transparency for raw durability. Pick the curtain first, then the control and speed — that order keeps the spec honest.
