Sliding Hangar Doors

Cronax Horizontal Sliding Aircraft Hangar Doors are engineered to provide maximum clear opening widths for aircraft of all sizes. Designed with large sliding panels that move smoothly along floor-mounted or top-supported tracks, these doors are ideal for hangars where vertical lifting is not practical. Built from high-strength steel or aluminium, the doors withstand high wind loads, harsh weather, and heavy-duty use. Their modular panel system allows single, bi-parting, or multiple-panel configurations, ensuring flexibility to meet specific hangar requirements.

Fitted with motorized or manual operation systems, they deliver smooth, effortless movement, while safety features such as obstruction sensors and emergency controls guarantee reliable operation. With their robust design, low maintenance, and adaptability, Cronax Horizontal Sliding Aircraft Hangar Doors are a proven solution for airports, MRO facilities, private hangars, and defense aviation bases.

CUSTOMIZATION OPTIONS

Door Type	Heavy-duty horizontal sliding aircraft hangar door, bottom-rolling with top guidance, designed for seamless side-to-side operation without requiring headroom.
Primary Application	Aircraft hangars, MRO facilities, logistics bays, and structures where vertical clearance is limited, but side clearance is available.
Maximum Clear Opening	Unlimited width via modular multi-panel design; each leaf can slide into side pockets or along outriggers (uni-directional, bi-parting, floating configurations supported).
Operating Speeds	Typically smooth and steady sliding, speeds designed per project specifics (~0.17 m/s).
Panel & Track Construction	Insulated steel or composite panels (PU or rock-wool cores) bonded to structural framing. Bottom track carries full door weight via bottom rollers; top guide ensures alignment and stability.
Sealing & Weather Protection	Advanced weather-seal systems, including brush or rubber seals at bottom, vertical edges, and head, providing wind-resistance and energy efficiency.
Wind & Structural Performance	Constructed to resist high wind loads; structural track members engineered per regional codes; rollers and tracks sized for vertical loads and lateral forces.
Compliance & Standards	Engineered to meet IS/BS/EN and hangar-specific structural standards; certified for wind load resistance and operational safety.

Drive System	Options include bottom-mounted traction drives, unit drives, or rack-driven operators (chain or gear) tailored to door size and type (unidirectional, bi-parting, floating).
Power Supply	Typically 3-phase 400/415 V, with single-phase options for smaller doors; emergency generator or UPS support available.
Control Panel	Digital control panels with soft-start/stop, overload protection, and safety interlocks; compliant with NEMA / ICS standards.
User Controls	Wall-mounted push-button station (Open/Stop/Close); optional remote control, key-operated access, or integration with BMS and security systems.
Safety Systems	Includes auto-reverse safety edges, anti-crush sensors, limit switches, and warning alarms or strobes to signal movement.
Positioning	Precision positioning via limit switches or encoder systems ensures accurate open and closed stops.
Emergency & Backup	Manual chain or crank override for power outages; optional battery backup provides continued operation.
Integration	Compatible with building automation systems (BMS), fire alarms, runway lighting, and aircraft docking systems.

Panel Finish	Standard insulated steel panels in powder-coat; optional stainless steel or custom RAL color finishes available.
Insulation Options	Polyurethane (PU) or rock-wool core for thermal and acoustic performance tailored to environmental requirements.
Vision Panels & Access	Optional glazed or polycarbonate vision inserts; integrated pedestrian/tail doors available without altering thresholds.
Sealing Packages	Enhanced brush or rubber seals along bottom, sides, and head for weather-tight closure and energy efficiency.
Branding	Custom finishes, safety striping, or logo screen-printing customizable to client branding needs.
Accessories	Options such as warning lights, motion sensors, heating, smart monitoring, and door position indicators available.
