Helicopter Hangar Door
The Madoors USA Helicopter Hangar Door is a large-scale, bespoke automatic motorized hangar door system engineered for private and business helicopter hangars, helicopter maintenance and refurbishment facilities, naval vessel and scientific research vessel onboard helicopter hangars, military helicopter installations, and aircraft manufacturer production halls — delivering long-lasting reliable operation, high-class appearance, and bespoke design for any opening size and application across decades of service. Designed to perform in the harshest environments — polar and tropical climates — and available with certification for water tightness, gas tightness, and fire resistance on request, Madoors USA helicopter hangar doors are configured as sliding doors on rails with unlimited opening width, stacking doors for openings up to 15 meters, and upward-opening bi-fold and simple opening configurations — all supplied with electrical or hydraulic actuators, control panels, local control button boards, backup manual operating systems, and optional de-icing systems.
TECHNICAL SPECIFICATIONS
Madoors USA Helicopter Hangar Doors are available in the following primary configurations.
Sliding doors on rails provide unlimited opening width — additional door sashes can be added to the sliding system without structural limitation, allowing any opening width to be covered by a single coordinated sliding door installation. Rail-guided sliding doors are the standard configuration for the widest helicopter and aircraft hangar openings where the building facade spans are too wide for stacking or folding alternatives.
Stacking doors provide a space-saving configuration for openings up to 15 meters — with door blades parking vertically in a self-bearing stack behind the lintel in the open position. This vertical stacking behind the lintel eliminates the side run-back requirement of sliding doors and the overhead clearance requirement of upward-opening doors, making the stacking configuration the preferred choice where building layout constraints prevent run-back space alongside the opening.
Upward-opening configurations include simple opening — the door panel lifts directly upward — and bi-folding — the door panel folds at a central horizontal hinge as it rises, reducing the vertical lift clearance required above the door. Both upward-opening configurations can include a secondary personnel passage door for pedestrian access when the main hangar door is in the closed position.
Main door system components include the hangar door panel, hangar door frame, mechanical components — hinges, bushes, and connecting hardware — actuators — hydraulic cylinders or electrical actuators — locking pins, control panel, local control button board, backup manual operating system, and optional de-icing system for installations in cold climate environments where ice accumulation on door panels and tracks creates operational risk.
Optional cladding includes sandwich panels and trapezoidal sheets for the door panel exterior finish. Windows can be integrated as mineral glass windows, strip windows, or in-door solutions within the door panel. Low-weight aluminum frames provide corrosion resistance without any maintenance requirement — particularly important for naval vessel applications where salt spray corrosion is a continuous exposure condition.
KEY FEATURES
Unlimited Opening Width — Sliding Rail Configuration
The sliding door on rails configuration accommodates any opening width through the addition of door sashes — with no structural limit on the total opening that can be covered by a single coordinated sliding installation. This unlimited width capability makes sliding rail configuration the definitive solution for the largest commercial aircraft, wide-body helicopter, and military aircraft hangar openings where fixed-width door configurations cannot provide complete facade coverage.
Stacking Door — Up to 15-Meter Opening, Behind-Lintel Parking
The stacking door configuration provides a space-saving, self-bearing vertical stack behind the lintel for openings up to 15 meters — eliminating run-back space requirements alongside the opening and providing a clean, unobstructed building facade in the open position without visible door panels extending beyond the building line. Self-bearing vertical stacking eliminates the structural support requirement for a side wall or column to receive the stacked door panels, providing installation flexibility where no adjacent structural support is available.
Upward-Opening Configurations — Simple & Bi-Fold
Simple upward-opening provides direct vertical panel lift for hangars with sufficient overhead clearance above the door. Bi-fold upward-opening reduces the required vertical clearance by folding the panel at its center as it rises — making the bi-fold configuration the appropriate choice for hangars where available overhead clearance above the door limits the use of simple upward-opening panels. Both configurations provide complete and clear opening of the hangar facade with no door hardware obstructing the aircraft approach path.
Secondary Personnel Door — Pedestrian Access When Closed
A secondary in-door personnel passage door is available in all configurations — providing pedestrian access through the hangar door when the main door panel is in the closed position without requiring the full hangar door to be opened for single-person access. This personnel door reduces the energy loss, security exposure, and operational disruption of opening the full hangar door for routine pedestrian access throughout the working day.
Hydraulic & Electrical Actuator Options
Two actuator types cover different power infrastructure, force output, and operational requirements. Hydraulic cylinder actuators provide the highest force output for the heaviest door panel weights and the widest opening spans — with consistent force delivery independent of electrical supply fluctuations. Electrical actuators provide energy-efficient, precise position control for standard door weights with straightforward integration into building management and access control systems.
Backup Manual Operating System
A backup manual operating system is provided as standard — allowing the hangar door to be opened and closed without electrical or hydraulic power in the event of a primary system failure. This manual backup ensures operational continuity for helicopter and aircraft departure and recovery during system failures and power outages — critical for emergency services helicopter hangars, military installations, and naval vessels where door failure must not prevent aircraft operations.
De-Icing System — Polar Climate Operation
Optional de-icing systems prevent ice accumulation on door panels, frames, tracks, and mechanical components in cold climate installations — maintaining reliable door operation in the freezing temperatures and ice formation conditions of polar and northern climate helicopter hangar sites. De-icing system specification is determined by the minimum ambient temperature and precipitation conditions of the installation location.
Water Tightness, Gas Tightness & Fire Resistance Certification
Certification for water tightness, gas tightness, and fire resistance is available on request — providing independently verified performance documentation for applications where one or more of these properties is a regulatory or operational requirement. Water tightness certification is essential for naval vessel onboard helicopter hangars where the door must maintain watertight integrity in sea conditions. Gas tightness certification applies to installations where fuel vapor or toxic gas containment is required. Fire resistance certification covers hangar facilities where fire-rated door closures are required by building codes or insurance specifications.
Polar & Tropical Climate Engineering
The door system is specifically engineered for operation in both polar and tropical climate extremes — with material specifications, seal compounds, lubrication systems, and actuator configurations selected for reliable performance across the full range of temperatures, humidity levels, UV exposure, salt spray, and precipitation conditions encountered at helicopter hangar installations worldwide. This climate range engineering makes Madoors USA hangar doors suitable for deployment from Antarctic research station hangars through to equatorial military and commercial aviation facilities.
Naval Vessel & Research Vessel Application
The Madoors USA helicopter hangar door is specifically designed for installation on naval vessels and scientific research vessels — where the combination of salt spray corrosion, vessel motion, tight space constraints, water tightness requirements, and continuous operational reliability demands creates the most technically challenging hangar door installation environment. Low-maintenance aluminum frame construction, water tightness certification, and harsh environment engineering are all directly relevant to the naval vessel application.
Bespoke Design — Each Door Entirely From Its Own Design
Every Madoors USA helicopter hangar door comes entirely from its own design — there are no standard products that are adapted to the project. Each door is individually designed, manufactured, and assembled for the specific opening dimensions, operating environment, cladding specification, certification requirements, and performance parameters of the project. This bespoke design approach provides the optimum technical and visual solution for each application without the compromise of adapting a standard product to non-standard requirements.
Mineral Glass, Strip Windows & In-Door Vision Options
Window integration options — mineral glass windows, strip windows, and in-door integrated solutions — provide natural light and visibility through the door panel in the closed position, maintaining the visual openness and natural light penetration of the hangar facade when the door is shut. Window specification is coordinated with the door panel structural design to maintain blast, water, or fire resistance certification at all glazed apertures where applicable.
Sandwich Panel & Trapezoidal Sheet Cladding Options
Optional metal cladding with sandwich panels or trapezoidal sheets provides weather-resistant, thermally insulating exterior finish for the door panel — matching the cladding character of the surrounding hangar building facade and providing the thermal insulation required for climate-controlled helicopter maintenance and storage facilities.
Low-Weight Aluminum Frames — Corrosion-Free, Maintenance-Free
Low-weight aluminum frame construction provides inherent corrosion resistance throughout the frame service life without requiring surface treatment maintenance — a critical advantage for naval vessel applications and coastal installations where the corrosion exposure conditions would rapidly degrade steel frames without continuous maintenance intervention.
