Stacking Doors
A stacking door gathers its curtain upward in folds rather than rolling it onto a drum, which is how very large openings get fast operation without an oversized head unit. Hangars, aircraft maintenance bays, large transfer openings and industrial halls use them because the alternative is a slow sectional door or a shutter that takes half a minute to close. The system is a compromise between speed, span and wind performance, and the balance point has to be set for the specific opening rather than copied from a catalogue.

Рекомендации по выбору
- State the opening span first; stacking doors are chosen by span, not by model number.
- Confirm the wind requirement for external openings, as the fold-up construction responds differently from a rolling curtain.
- Check the stowed height: the folded stack occupies space above the opening.
- For hangars and very large bays, the operating logic and the safety zone need to be designed with the door, not after it.
Частые вопросы
- What is the advantage over a roller shutter?
- Speed and span. A stacking door closes large openings much faster than a conventional shutter.
- How much space does it need above the opening?
- The folded stack needs headroom that scales with the opening height. It is confirmed from the drawing at enquiry stage.
- Can it operate outdoors?
- Outdoor installation is possible with the wind requirement stated, which changes the reinforcement.
- Is a pedestrian access door available?
- Wicket doors can be integrated where the design requires personnel access without cycling the main opening.
