The RAX Industrial Folding Door is a heavy-duty bi-fold door system designed for large-span openings where conventional swing or sliding doors are impractical. The door panels fold vertically (stacking above the opening) or horizontally (accordion-style), consuming minimal wall or ceiling space compared to sliding alternatives. This makes folding doors the preferred solution for aircraft hangars, helicopter pads, agricultural machine sheds, boat houses, and industrial buildings where overhead clearance must be preserved.
As a pure manufacturer since 1999 with a 11,000 m² production base, 170+ staff, and 20+ R&D engineers, RAX produces each folding door to your exact opening dimensions — from a single unit, with no minimum order. Every door is factory-tested against a 100,000-cycle fatigue protocol and shipped with complete wiring diagrams, and English manuals for your local installation team. [SOURCED — RAX claim]
In the global market, bi-fold hangar door specialists such as Schweiss (US) build folding doors up to 120 ft (~36.6 m) width using lift straps, hydraulic cylinders, or bottom drive motors, with cladding options including wood, translucent panels, and built-in windows. [SOURCED: bifold.com] Hangar span classes range from < 30 m (S) to > 120 m (XXL). [SOURCED: Wikipedia] RAX offers both vertical bi-fold and horizontal bi-fold configurations, custom-engineered to your span and wind-load requirements. [SOURCED — RAX claim]
