Fire-resistant steel roller shutters are designed to provide both fire protection and physical separation between two areas. They are always equipped with an electric drive and are particularly suitable for facilities with relatively low traffic frequency.
Thanks to their combination of fire protection, physical separation and cost-effective design, these shutters are widely used in industrial facilities, production halls and warehouses.
The shutter curtain rolls onto a shaft installed above the building opening, eliminating the need for lateral clearance. This space-saving design allows the shutter to be installed in a wide range of industrial applications.
Depending on the specific configuration, the shutters achieve fire resistance ratings from EW 15 to EW 90.
The shutter curtain consists of double-skinned horizontal steel slats filled with mineral wool.
The slats move along guide rails and roll onto a shaft positioned above the building opening when the shutter opens.
The shutter is manufactured from galvanised steel sheet as standard and is equipped with an electric drive featuring an integrated safety brake.
A backup power supply ensures that the shutter can close even in the event of a power failure.
Fire-resistant industrial roller shutters are manufactured according to individual project requirements, including the required functionality and opening dimensions.
Fire-resistant roller shutters are primarily designed for indoor installation, where they serve as fire-resistant closures separating individual fire compartments.
When installed in the external envelope of a building, the shutters must be fully protected against weather conditions, for example by a canopy, enclosed entrance area or similar structure.
This is because performance characteristics such as watertightness, resistance to wind load, thermal transmittance and air permeability have either not been determined or have been assigned Class 0.
The roller shutters are tested and certified by independent institutions and comply with the requirements of EN 13241:2003+A2:2016 and EN 16034:2014.
Individual components, excluding the drive and control unit, are manufactured at our production facility in accordance with the quality and environmental management systems ČSN EN ISO 9001:2020 and ČSN EN ISO 14001:2020.
A safety contact edge is fitted to the bottom edge of the shutter curtain.
If the shutter accidentally comes into contact with an obstacle during closing under normal operating conditions, its direction of movement is automatically reversed.
In the event of a fire alarm, the shutter closes automatically upon receiving a signal from the fire detection and fire alarm system (FDAS), a smoke detector or a temperature detector.
The roller shutter is equipped with an electric drive and an integrated safety brake, providing protection against uncontrolled movement of the shutter curtain.
The drive system includes a backup power supply, ensuring that the shutter closes in the event of a power failure.
The drive and integrated safety brake are individually sized according to the weight of the rolled-up shutter assembly for each project.
The shutter curtain consists of double-skinned horizontal steel slats interconnected by a special locking system. The slats are filled with mineral wool, providing the required fire-resistant properties. The shutter curtain moves along guide rails and rolls onto a shaft mounted on supporting brackets.
The shutter operates at a speed of 0.15 m/s. As standard, the shutter is manufactured from galvanised steel sheet. A surface finish in a selected RAL colour is available upon request.
During normal operation, the roller shutter is opened and closed using the buttons on the control unit, with impulse activation.
