Engineered high-durability sliding fire barriers designed for warehouses, workshops, and automated transit systems.
The Port of Antwerp-Bruges stands as Europe's second-largest port, functioning as a vital maritime entry point and a leading hub for chemical, petrochemical, and automotive logistics. Operating in these environments demands strict adherence to rigorous safety standards. Structures built in close proximity to saline maritime air require materials that resist corrosion, while facilities handling chemicals must plan for high-stakes thermal mitigation. Consequently, standard architectural components are often insufficient for these projects.
Belgian Royal Decrees (KB/AR of 7 July 1994 and its amendments) alongside the overarching European Standard EN 16034 mandate strict fire-resistance (EI1 / EI2 classifications) and structural resilience for compartmentalized boundaries. Automated sliding fire doors serve as critical assets here, offering wide openings for industrial vehicles while ensuring automatic containment in the event of thermal anomalies.
"Safety in the chemical clusters of Linkeroever and Rechteroever depends on reliable passive fire barriers. Our automated sliding fire doors are built to perform reliably even under the harsh corrosion conditions of the Scheldt estuary."
Internationally, the automated fire doors industry is shifting toward smart, integrated networks. Modern commercial buildings and production lines no longer rely on standalone fire doors. Instead, they require doors that connect directly with complex Building Management Systems (BMS) and intelligent fire detection networks.
Reinforced fire protection systems engineered for durability in busy industrial facilities.
Underneath the simple sliding mechanism lies a sophisticated assembly of materials science and electrical safety systems designed to prevent failure.
| Outer Shell | Galvanized high-tensile steel or anodized industrial aluminum profiles. |
| Thermal Core | Multilayer high-density mineral wool with integrated silicate-based fire prevention boards. |
| Expansion Seal | Temperature-activated intumescent seals that expand up to 25 times their size at 150°C. |
| Hardware Fitting | Stainless steel heavy-duty sliding track system with dual-wheel bottom rollers. |
| Controller | Microprocessor intelligent controller integrating with MODbus / BACnet protocols. |
| Motor Type | Heavy-duty brushless DC motor (e.g., Turtech series) with variable frequency speed settings. |
| Failsafe Drive | Electromagnetic clutch that disengages upon power loss, allowing gravity-driven mechanical closure. |
| Safety Systems | Built-in optical radar detectors, pressure sensitive edges, and redundant battery backups. |
In modern industrial design, fire doors do not function as isolated components. Our research and development focuses on the *Tri-Level Safety System*, which links physical barrier performance, electromechanical automation, and sensor-driven environmental awareness. When sensors detect smoke or high heat, the doors receive a direct command from the central alarm system. The controller immediately stops normal traffic mode and changes to emergency mode, ensuring the door closes safely and completely to contain the hazard.

The distinction lies in the location of the temperature sensors during test procedures. EI₁ measures insulation performance with sensors positioned closer to the door frame, making it a more challenging rating to achieve. It is often required in specific public spaces and exit pathways across Belgium. EI₂ allows sensors to be placed further from the frame. Both ratings reflect the door's capacity to contain smoke and heat, but EI₁ indicates a higher level of thermal resistance.
Our automated doors utilize a gravity-assisted close or mechanical spring backup system. Under normal operations, an electromagnetic clutch holds the door open. In the event of a power outage or fire alarm trigger, the clutch releases automatically. This allows a mechanical counterweight or internal spring mechanism to close the door at a controlled rate, even without electrical power.
Yes. Standard steel doors can rust quickly in coastal conditions. Our composite doors combine structural steel cores for strength with anodized aluminum exterior cladding for corrosion resistance. Additionally, we apply multi-layer epoxy powder coatings designed for C5 marine environments, protecting the doors from salt mist and moisture damage.
Yes, they are compatible. The intelligent motor controllers (such as the Turtech Casa1 systems) feature interface relays that communicate with standard fire safety protocols. This allows you to monitor door status (open, closed, or faulted) and trigger closures directly from your building control system.
