The 400-FBR is a mid-range, bottom-rolling, insulated steel folding door, purpose-built for openings up to 30 metres wide and 9 metres high. Ideally suited for large helicopter bays or medium-sized aircraft hangars, it offers both performance and space efficiency. When opened, the leaves fold neatly into compact stacking areas, ensuring unobstructed access across the full height and width of the opening—maximising internal hangar space and operational flexibility.
Accommodates openings up to 9 metres high by 30 metres wide.
No need for a load-bearing portal frame — door weight is fully supported at floor level.
Power operated as standard, with hand-wind versions also available.
Minimal bunching footprint — a 30-metre wide bi-parting door stacks into less than 2 metres beyond each jamb.
Front-edge control system allows the operator to walk the door open and closed for enhanced visibility and control.
Inverter-controlled drive system ensures smooth acceleration and deceleration for safe and quiet operation.
Flush-mounted single bottom track set into the floor for seamless threshold and unobstructed movement.
Full factory finish available in any RAL colour.
All structural components — frames, mullions, and sliding posts — are galvanised prior to final coating for long-term corrosion resistance.
