Aircraft and machine hangars demand some of the largest door openings in industry — hangar spans are conventionally classed from S (<30 m) up to XXL (>120 m) [SOURCED: en.wikipedia.org/wiki/Hangar] — and the bi-fold door is the vertical-lift answer for sites where no floor track can cross the apron. Two hinged leaf panels fold upward against the lintel, leaving the full opening clear below and nothing sliding across the threshold, which keeps taxiways, rail spurs and dock aprons completely unobstructed.
In industry practice, bi-fold hangar leaves are lifted by lift straps or hydraulic cylinders, with cladding options from insulated steel skins to translucent panels and built-in vision windows; US hangar-door specialists reference bi-fold installations at spans up to 120 ft (≈36.6 m) [SOURCED: www.bifold.com/q-list.php?id=ZZ_-Aviation_Hangar_Doors]. RAX engineers each Bi-fold Hangar Door to your structural opening — leaf geometry, hinge and strap hardware, wind bracing and drive sizing are all calculated per project — and, as a pure manufacturer (no on-site installation), ships the complete door with English manuals your local team needs to install it. From a single unit, with full order flexibility.
Leaves fold vertically against the lintel — no ground rail to obstruct aprons, tow paths or drainage, a decisive advantage over sliding layouts on hangars and boathouses.
Multi-panel leaf construction with wind bracing, sized against your declared EN 12424 wind class; wide spans use segmented leaves rather than one unwieldy panel.
Hinges, straps and hardware validated against a 100,000-cycle fatigue testing protocol in the RAX in-house lab; drives tested from −30 °C to +50 °C.
ISO 9001:2015 and CE to EN 13241 / EN 12453, with SGS material reports. Foundation and track loads documented for your civil engineer.
Leaf cladding to your spec — insulated steel skins, aluminum profiles or translucent sections with vision windows, in any RAL color.
English manual + wiring diagrams; operator pre-set and test-run recorded before dispatch.
| Product | Bi-fold Hangar Door (also: Vertical Bifold Door · Horizontal Bi-fold Door) |
| Category | Industrial Doors |
| Door action | Two hinged leaves per bay fold upward against the lintel; lift by straps or hydraulic cylinders with bottom drive motor options — mechanism configurations used across the hangar-door industry [SOURCED: www.bifold.com/q-list.php?id=ZZ_-Aviation_Hangar_Doors] |
| Size range | Engineered to your opening. Hangar openings span from <30 m to >120 m classes [SOURCED: en.wikipedia.org/wiki/Hangar]; US specialists reference bi-fold doors to ≈36.6 m (120 ft) [SOURCED: bifold.com]. RAX confirms your feasible span, leaf segmentation and wind bracing on the technical layout — any size, fully engineered to your specification. |
| Operating speed | Large hangar doors move slowly due to leaf mass; industry-typical ≈0.1–0.2 m/s [ESTIMATE]. Final speed per drive sizing on your project. |
| Wind load | Classified to EN 12424 / EN 12444, Class 0–5 (Class 5 = above 1,000 Pa, by special agreement) [SOURCED: baijiahao.baidu.com/s?id=1758406178830937742]. Exposed hangar sites typically need Class 3–5, and the achievable class falls as span grows — RAX declares the class at your full span [ESTIMATE]. |
| Materials | Galvanized steel sheet 0.4–1.5 mm, aluminum alloy 6063-T5 profiles, stainless 304/316 or PVC-coated fabric 0.9–1.2 mm cladding options per project; silicone rubber seals. |
| Color / finish | Full RAL custom (common RAL9006 / 9010 / 7016 / 5010), wood-grain, PVDF, anodizing. |
| Drive & control | Servo / VFD drive options; radar, geomagnetic or light-curtain sensing; WiFi / RS485 remote monitoring (Industry 4.0 ready). |
| Certification | CE EN 13241 / EN 12453; wind (EN 12424) test or calculation data confirmed per project. |
| Order | Custom engineered to your exact opening, specification and RAL color. |
RAX company facts above come from the approved brand brief. Figures marked [SOURCED] are industry/competitor data with the source shown inline; figures marked [ESTIMATE] are industry-typical and are confirmed against your technical layout before production.
Provide clear opening width × height and the hangar span class (S <30 m up to XXL >120 m). We return leaf segmentation and a technical drawing confirmation.
Declare your design wind pressure so we select the EN 12424 class and bracing; exposed coastal or airfield sites should target the higher classes.
Choose insulated skins, aluminum or translucent panels and built-in windows to balance weight, daylight and thermal loss.
Strap vs hydraulic lift, sensing and interlocks, plus foundation / lintel loads issued to your civil engineer before production.
RAX supports full private-label production of the Bi-fold Hangar Door: custom RAL panel colors, operator matching, packaging printing and installation-manual translation (EN/ES/FR/AR/RU). Start with an OEM sample and scale to container-load branded production. Custom molds, Tooling records are archived for up to 5 years — no extra tooling fee on repeat orders, all under strict NDA.
Industrial, commercial and garage doors and gates — the harmonized basis for CE marking, including wind (EN 12424), thermal (EN 12428) and air-permeability (EN 12426/12427) declarations.
Safety in use of power-operated doors — operating force limits and entrapment protection for the drive system.
Wind load resistance classification, Class 0–5 — the key declaration for an exterior hangar door, stated at the full opening span.
Each door is engineered to your opening. Hangar openings are conventionally classed from S (<30 m) to XXL (>120 m) [SOURCED: en.wikipedia.org/wiki/Hangar], and US hangar specialists reference bi-fold doors to about 120 ft / 36.6 m [SOURCED: bifold.com]. Share your width × height and our engineers confirm the feasible span, leaf segmentation and wind bracing on a technical layout — from prototype to full production runs, full flexibility on order quantity.
Industry practice is lift by straps or hydraulic cylinders, with bottom drive motor options [SOURCED: bifold.com]. Because the leaves are heavy, bi-fold hangar doors typically run at about 0.1–0.2 m/s [ESTIMATE]; we size the drive and confirm the speed for your door on the technical layout.
Wind resistance is classified to EN 12424 / EN 12444 from Class 0 to Class 5 (Class 5 = above 1,000 Pa) [SOURCED: baijiahao.baidu.com/s?id=1758406178830937742]. Large exterior hangar doors on exposed sites generally need Class 3–5, and the class falls as span grows, so we declare the class achieved at your full opening span [ESTIMATE].
We are a pure manufacturer and do not provide on-site installation. Every order ships with an English installation manual, installation guides, wiring diagrams and foundation load data for your local installation team; operators are pre-set and tested before dispatch.
RAX holds ISO 9001:2015 and CE to EN 13241 (industrial door) and EN 12453 (operator safety), with SGS material reports and product liability insurance. Wind performance is declared per EN 12424 per project; we can also support AS/NZS 4505 and UL counterpart test data for Australian and North American markets.
Yes. RAL panel colors, operator matching, packaging printing and manual translation (EN/ES/FR/AR/RU) are all supported, from an OEM sample to container-load branded production, under NDA.
