Fire-resistant spiral roller shutters are designed to separate fire compartments within industrial halls and buildings. They are particularly suitable for industrial facilities, production halls and warehouses.
The shutter slats roll into a spiral supported by steel brackets, leaving a gap between the individual slats when the shutter is fully rolled up. This prevents the slats from rubbing against one another, protecting their surface finish from the wear and damage commonly associated with conventional roller shutters.
Another important advantage of spiral roller shutters is the possibility of combining fire resistance and smoke-tight construction in a single system.
The shutter curtain consists of double-skinned horizontal steel slats filled with geopolymer material and mineral wool.
The slats move along guide rails on rollers and are wound into a spiral by means of a chain drive. The spiral assembly is supported by steel brackets.
The shutter is manufactured from galvanised steel as standard and is equipped with an electric drive, an integrated safety brake and a backup power supply.
A safety contact edge is fitted to the bottom edge of the shutter curtain. If the shutter comes into contact with an obstacle during closing, the direction of movement is automatically reversed to prevent damage or injury.
The spiral roller shutter is equipped with an electric drive and an integrated safety brake, providing protection against uncontrolled movement of the shutter.
The drive system includes a backup power supply, ensuring that the shutter can close even in the event of a power failure.
The drive and safety brake are individually sized according to the weight of the rolled-up shutter assembly for each project.
In the event of a fire alarm, the shutter closes automatically upon receiving a signal from the fire detection and fire alarm system (FDAS).
The shutter curtain moves along guide rails on rollers and is wound into a spiral by means of a chain drive.
The spiral assembly is mounted on supporting brackets, ensuring that the individual slats remain separated during winding and do not rub against one another.
The shutter operates at a speed of 0.07 m/s.
The shutter curtain consists of double-skinned horizontal steel slats interconnected by bolted hinges.
The slats are filled with geopolymer material and mineral wool, providing the required fire-resistant properties.
As standard, the shutter is manufactured from galvanised steel. A surface finish in a selected RAL colour is available upon request.
Fire-resistant spiral roller shutters are manufactured according to individual project requirements, including the required functionality and opening dimensions.
