PRODUCT · FABRIC DOORS FOR LARGE OPENINGS
Vertical lifting fabric doors for the widest openings we build: the leaf travels flat into the header, so the full structural opening stays clear and nothing sweeps the space in front of the door. Manufactured from PVC-coated technical fabric, with the leaf, the guide columns and the header loads calculated together with your building.
PVC-coated technical fabric, welded into horizontal panels with an aluminium section at each joint and a continuous keder along both vertical edges. The keder is what holds the leaf in the guide — not the fabric itself.
Each panel joint carries a roller that travels in the guide column. The load path is leaf → keder → roller → guide → column → building, and every step of it is calculated for the opening rather than taken from a table.
A shaft at the head takes the leaf up in one plane. Nothing folds outward, nothing swings into the building, and the full structural opening stays clear while the door is moving.
Positive engagement between leaf and guide at intervals up the opening, so a gust cannot peel the fabric out of the rail. This is where the EN 12424 class is actually won.
Head, jambs and sill are sealed as a perimeter. On a heated building the leaf is specified as part of the envelope, with the insulated variant where the heating bill justifies it.
Full clear width and height with nothing sweeping the apron, sized to the tallest tail in the fleet rather than to the structural opening. The default door family for hangar bays and the reason vertical lift dominates aviation.
Aircraft hangar doors →Air bases are cleared, flat and frequently coastal, so the governing wind class is usually the worst on the elevation. Calculated per building, documented for the tender, references anonymised.
Military & defence hangar doors →Openings sized for a hull section, in terrain category 0 with salt air on the fixings. Guide columns and fixings specified for the exposure rather than for the catalogue class.
Shipyard doors →Where a live crane rail crosses the opening, the vertical lift leaf clears the rail without losing hook height. Constant traffic, heat and dust are cycle-count questions, and they are answered in the drive selection.
Heavy industry doors →Where there is almost nothing above the lintel, the leaf folds into a compact stack instead of lifting flat — including openings beneath a live craneway. Headroom required 0.9 m. It is the retrofit answer when the building was never designed around a door.
The fold-up leaf clears a rail the vertical lift leaf would have to travel through. Hook height is unchanged and the rail is not modified — which is usually the difference between a possible project and an impossible one. Fabric fold-up doors →
Both families are flexible lifting doors built from the same PVC fabric, the same keder-and-roller load path and the same classification route.

Dotted values are placeholders awaiting the manufacturer’s technical data. Nothing in this table is a commitment until it appears in an offer for a specific opening — and no figure here has been rounded up to look better.
Three-button control at the opening as standard — open, stop, close — with the option of remote, loop, radar or card-reader release where the traffic pattern justifies it. The drive is selected against the cycle count you actually run, not the one in the brochure.
The projects below are illustrative of the type of work we do, not released references. Every span, height and class is dotted because none of them is confirmed yet — real references, named or anonymised, replace them once the client releases them.
CENTRAL EUROPE
Vertical lift leaf inside a heated hall, specified for cycle count rather than for span. The fitter at the panel gives the scale.

NORTHERN EUROPE
Installed into a hangar in service, with the guide columns fixed to the existing frame after survey and calculation of the reactions.
Request the reference sheet →Two vertical lift doors on a NATO-standard hangar. Client, site and photography under restriction.
Request the reference sheet →Product is already set to fabric vertical lift. Give us the opening and the site and we come back with a class, a drive configuration and a price — usually within three working days.
Also tendered as: vertical lift fabric doors, PVC fabric doors, fabric hangar doors, flexible lifting doors. Same product, same classification route.
