Vervaeke Bisondoor
Bisondoor Reinforced Rollerdoor
Secure your livestock housing, grain stores, and machinery sheds with the Bisondoor—an ultra-tough, reinforced rollerdoor system engineered specifically for demanding farm conditions. Built to cover openings up to 6 metres wide and 6 metres high, the Bisondoor combines the breathability or weatherproofing of high-strength technical fabrics with the structural rigidity of heavy-duty metal profiling, offering unmatched wind load resistance against harsh weather conditions.

Description
Built for Corrosive Farm Environments
Corrosive slurry fumes, constant moisture, and chemical washdowns can quickly destroy low-grade door hardware. To deliver a long lifespan in these harsh conditions, every essential component of the Bisondoor is either hot-dip galvanized or extruded from aluminum, and assembled exclusively using stainless steel fasteners.
The door requires a minimum overhead clearance of 45 cm at the top of the opening for the roll assembly, mounting directly onto your existing structural stanchions.
Key Technical Benefits & Features
-
Custom Dimensions Up to 6m x 6m: Made-to-order sizing to fit medium-to-large machinery entrances, feeding passages, and livestock sheds.
-
Superior Wind Load Resistance: Integrated horizontal aluminum profile bars lock into side guide tracks to prevent blowout during storms.
-
Hot-Dip Galvanized & Stainless Hardware: Maximum corrosion protection against slurry, moisture, and high humidity inside farm buildings.
-
Versatile Drive Options: Available as a cost-effective manual operation system or equipped with a powerful electric drive motor.
-
M2 Fire-Retardant Fabrics (in option) : All textile selections meet strict European flammability class M2 standards for enhanced farm safety.
-
CE Certified Engineering: Fully compliant with European health, safety, and structural directives for industrial and agricultural doors.
Tailored Fabric Configurations & Sight Windows
We weld all door curtains to order in our factory, allowing you to combine different fabric types to achieve the ideal balance of light, air, and shelter:
-
Hybrid Breathable & Solid Curtains: Combine an opaque, windproof tarpaulin lower section to block dirt, dust, and ground drafts with a breathable upper mesh panel for natural ventilation.
-
Transparent Vision Strip: Option to integrate a 50cm clear PVC viewing panel at eye level, allowing operators to safely check outside conditions or incoming traffic before opening the door.
-
Wide Color Palette: Choose from multiple agricultural colors per windbreak factor to match your site’s existing cladding.
Advanced Safety Systems
When equipping the Bisondoor with automated motor drives or remote controls, operator safety is paramount:
-
Auto-Reverse Safety Bottom Edge: Mandatory for automated or remotely operated doors. If the descending door senses any obstruction at the bottom edge, it automatically stops and reverses fully to the top position.
-
Controlled Descent: The motor only resumes downward travel upon a manual button press, protecting livestock, workers, and machinery from impact injuries.
