Description
Sliding fire door for large industrial openings with compartmentation requirements
The leaf slides sideways in normal operation and closes automatically on a fire alarm signal, guaranteeing compartmentation of the sector without obstructing passage during normal working conditions.
Technical specifications
- Type: sliding fire door for wide openings
- Classification: EI 60 / EI 90 or higher depending on model
- Steel leaf with non-combustible core (rock wool)
- Suspension system on fire-resistant steel top rail
- Gravity or spring closing mechanism on power failure
- Integrated smoke or rate-of-rise heat detector, or connection to the central system
- Intumescent perimeter seal
- CE marking
Advantages
✔ Suitable for large openings where hinged doors are not feasible
✔ Guaranteed automatic closing on any power failure (fail-safe)
✔ High fire resistance classification (up to EI 120 on some models)
✔ No sweep space needed when open
✔ Compatible with fire detection and control systems from any manufacturer
Applications
Large openings in industrial warehouses with mandatory fire sectors; access to large cold rooms in separate fire sectors; passages between industrial buildings with EI requirements above EI 60; logistics platforms with warehouses of different risk levels.
FAQs
Does the sliding fire door close on its own in a fire even if the power fails?
Yes. The fail-safe design ensures the door closes automatically on any power failure, whether caused by the fire itself or a supply cut. The closing mechanism (usually gravity assisted by a spring or counterweight) works independently of the power supply, which is only needed to hold the door open in normal conditions.
