Large Multi-Leaf Folding Industrial Door
Steel Accordion Door — Optimized for Wide-Span Commercial & Industrial Spaces
Product Overview
Our large multi-leaf folding industrial door is a versatile accordion-style folding door system designed for wide-span applications including warehouses, exhibition halls, sports facilities, and manufacturing plants. Featuring multiple steel leaves that fold together in a concertina fashion, this steel accordion door offers excellent space efficiency and a visually appealing aesthetic.
The door supports clear opening widths up to 50 meters and heights up to 15 meters. Each leaf is constructed from insulated steel sandwich panels with aluminum or steel frames, providing a balance of strength, thermal performance, and visual appeal. The folding mechanism operates on top-hung or bottom-supported tracks, with electric or manual operation options.
Width up to 50m Height up to 15m Accordion Folding Insulated Panels
Key Features & Technical Advantages
🔄 Compact Folding Mechanism
Leaves fold in a concertina pattern, stacking efficiently at one or both ends of the opening. Minimizes side-wall clearance requirements compared to sliding doors of similar width.
🧊 Insulated Panel Construction
Standard 40mm – 80mm thick steel sandwich panels with PU foam insulation. Available with mineral wool for fire-rated applications or non-insulated for internal use.
⚡ Electric or Manual Operation
Choose from electric motor drive with push-button/remote control, or manual operation with chain-pull mechanism. Ideal for applications where power supply is limited.
🎨 Architectural Versatility
Available in a wide range of RAL colors with powder-coated finish. Suitable for commercial showrooms, retail spaces, and customer-facing industrial facilities.

Frequently Asked Questions
What is the difference between a folding door and a sliding door?
A folding door uses hinges between leaves to fold the door in a concertina pattern, stacking compactly at the sides. A sliding door moves panels horizontally along tracks without folding. Folding doors require less side-wall clearance for a given opening width.
Can these doors be used for exterior openings?
Yes, with appropriate weather sealing, thermal insulation, and corrosion-resistant finishes, our multi-leaf folding doors are suitable for exterior applications including warehouse loading bays and storage facility entrances.
What type of maintenance is required?
Regular maintenance includes hinge lubrication, track cleaning, and periodic seal inspection. Our design features accessible lubrication points and replaceable wear components to simplify servicing.
Are electric drive options available for large doors?
Yes, we offer electric motor drives with frequency inverters for smooth operation on large folding doors. Dual-motor synchronization ensures even leaf movement across wide spans.
