What is the Maximum Size of a Hangar Flexible Door?

The maximum dimensions of a hangar flexible door depend on the manufacturer's engineering capabilities, structural constraints of the hangar, and specific operational requirements. Generally, modern flexible doors can span exceptionally large openings, with widths exceeding 60 meters (197 feet) and heights surpassing 20 meters (66 feet). Below is a detailed breakdown of common door types and their typical size limits, along with design considerations:

1. Sliding Door

Maximum Dimensions:  

Width: Unlimited (modular designs allow continuous expansion).  

Height: Up to 30 meters (98 feet).

Features:  

Ideal for ultra-wide openings, such as aircraft maintenance hangars.  

Utilizes heavy-duty tracks and reinforced panels to withstand wind loads and mechanical stress.  

Suitable for environments requiring unobstructed access and rapid deployment.

2. Sliding Folding Door

Maximum Dimensions:  

Width: Up to 50 meters (164 feet).

Height: Up to 16 meters (52 feet).

Features:  

Combines sliding and folding mechanisms to optimize space efficiency.  

Perfect for hangars with lateral space constraints.  

 Lightweight panels reduce operational wear, enhancing durability in high-frequency usage scenarios.

3. Side Swing Door

Maximum Dimensions:

Width: Up to 60 meters (197 feet).  

Height: Up to **15 meters (49 feet).  

Features:  

Operates via lateral hinges, enabling full-panel opening for oversized equipment transport.  

Reinforced frames and hydraulic dampers ensure stability in extreme weather conditions.  

Commonly used in military and industrial hangars requiring rapid access.

4. Overlap Door (Sectional Door)

Maximum Dimensions:

Single Panel Width: Up to 30 meters (98 feet).  

Height: Customizable based on structural design (no fixed limit).  

Features:  

Modular design with movable columns allows sectional operation, ideal for hangars with limited lateral clearance.  

Panels overlap during opening/closing, minimizing space occupancy.  

High flexibility for irregularly shaped openings or multi-door configurations.

Key Design Considerations

1.Material Strength:

   High-tensile fabrics (e.g., PVC-coated polyester) and aluminum/steel frameworks ensure load-bearing capacity and longevity.  

2.Wind Resistance:

   Engineering calculations for wind pressure (e.g., EN 12424 standards) dictate reinforcement requirements.  

3.Automation Compatibility:

Integration with motorized systems for remote operation and safety sensors (e.g., obstacle detection).  

4. Customization:

Manufacturers often tailor door dimensions, insulation, and sealing solutions to meet specific hangar needs.
