Bi-Fold Doors — Fast Operation for Large Industrial Openings
Bi-fold doors open fast and wide — ideal for aircraft hangars, fire halls, large warehouse bays, and agricultural facilities where a standard overhead door is too slow or too small. Wilcox installs and services bi-fold door systems across Canada for any large-format opening that needs reliable, high-speed access.
Built Wide. Built Fast. Built to Last.
Bi-fold doors are engineered for openings where speed and clearance are both critical. Wilcox works with your structural drawings to specify the right panel configuration, drive system, and weatherseal package. Certified Ironworker installation with full commissioning and documentation.
Advantages of Bi-Fold Doors
Bi-fold doors offer space-saving performance, design flexibility, and safety features, making them ideal for high-clearance and large-scale openings.
1. Space Optimization
- Bi-fold doors fold in half when opened, minimizing the space required for operation.
- This design reduces stress on the building structure and creates a slight slope, allowing water to run off efficiently.
2. Customizable Design
- Each bi-fold door is custom-made, with no restrictions or size limitations.
- This flexibility allows for seamless integration into new constructions or retrofitting existing buildings, ensuring a perfect fit for any project.
3. Enhanced Safety Features
- Lift Straps: Patented polyester lift straps replace traditional steel cables, offering quieter, faster, and more reliable operation. These straps have a longer lifespan and require less maintenance compared to cables.
- Automatic Strap Latches: These innovative latches firmly hold the door against the building in both open and closed positions, providing protection from wind gusts during operation and ensuring a secure seal when closed.
Technical Specifications & Performance
Our bi-fold doors are built with precision-engineered components to ensure superior performance, longevity, and minimal maintenance. Below are the key technical specifications:
Door Construction
- Frame Material: Heavy-duty steel or aluminum framework for enhanced strength and durability.
- Panel Options: Available in insulated, non-insulated, or glass panel configurations.
- Weatherproofing: Integrated gaskets and seals to prevent air and moisture infiltration.
- Finish Options: Powder-coated, anodized aluminum, or galvanized steel finishes for corrosion resistance and longevity.
Operational Performance
- Opening Speed: Varies based on door size and motor selection, typically up to 2 feet per second.
- Wind Load Rating: Engineered to withstand wind loads exceeding 90 mph, making them suitable for extreme weather conditions.
- Sealing System: Tight perimeter seals minimize energy loss and prevent drafts.
- Clear Opening Size: Custom-built to fit large-scale openings for hangars, industrial buildings, and commercial properties.
Automation & Control Options
- Manual Operation: Chain hoist or push-up operation available for smaller models.
- Motorized System: High-torque electric motors with variable frequency drive (VFD) for smooth operation.
- Remote Control: Wireless and smartphone-compatible controls for convenient access.
- Safety Sensors: Integrated obstruction detection and emergency stop functions for enhanced user safety.

Maintenance & Service Requirements
Proper maintenance is essential to ensure the longevity and reliable operation of bi-fold doors. Regular servicing helps prevent costly repairs and keeps doors functioning smoothly.
1. Routine Inspections
- Check for wear and tear on lift straps, hinges, and latches to ensure smooth operation.
- Inspect the door frame and structural components for signs of stress or misalignment.
- Ensure proper sealing and weatherproofing to prevent air or water infiltration.
2. Lubrication & Cleaning
- Apply appropriate lubricants to moving parts, including hinges, rollers, and locking mechanisms, to reduce friction and wear.
- Clean lift straps and guides regularly to prevent debris buildup that could hinder movement.
3. Operational Safety Checks
- Test the automatic locking and latch systems to confirm they are securely holding the door in place.
- Verify motorized or hydraulic systems function properly and that emergency stop features are operational.
- Monitor door balance and alignment to prevent uneven movement that could strain the system.
4. Professional Maintenance & Repairs
- Schedule annual maintenance checks with trained professionals to assess and adjust tensioning systems, structural integrity, and overall door performance.
- Address minor repairs immediately to prevent more extensive issues from developing.

Frequently Asked Questions
Commercial sectional doors are built for higher cycle counts (often 10,000+ cycles/year), heavier steel gauges, wider spans, and industrial environments. They're engineered for forklift clearance, insulation requirements, and continuous operation — very different from residential doors.
Annual preventive maintenance is the minimum. High-traffic facilities running 50+ cycles per day should schedule semi-annual PM. Regular service catches spring fatigue, cable wear, and weatherseal deterioration before they cause a failure or safety incident.
Most commercial sectional door installations take 1–2 days. Larger openings, custom panel configurations, or insulation upgrades may take 2–3 days. Wilcox works around your operation to minimize disruption.
We offer insulated panels from R-6.5 up to R-25.7 depending on the application. Cold storage, food processing, and pharmaceutical facilities typically require higher R-values. We specify the right insulation level for your temperature requirements.
Wilcox works with Clopay, Hörmann, Raynor, Amarr, Wayne Dalton, and most major commercial brands. We're not brand-exclusive — we recommend the right product for your opening, application, and budget.
