Manually-operated bi-fold doors.
Designed for use in openings of up to 6000 mm wide and 6000 mm high, and particularly suitable for applications where a bottom track needs to be avoided, such as railway depots.
The manually-operated, insulated bi-folding door has energy-saving qualities. It is designed for use in openings of up to 6000 mm wide and 6000 mm high, and is particularly suitable for applications where a bottom track needs to be avoided, such as railway depots. Its ease of operation allows the door to be manually-operated, unlike upward-moving doors such as sectional overheads and rolling shutters, particularly on larger openings.
The operation is simple and avoids the need for cables, springs, etc., thus avoiding high maintenance after installation. The door is sideways-opening, which means that the leading edge is in constant vision and less prone to damage from vehicles passing through the opening.
