Hangar and large-span doors for aviation, rail, marine and heavy plant buildings in Isleworth. We survey the opening and the structure, then design a door for its size and wind exposure before giving a fixed price.

What to specify
- Load path. We decide with your structural engineer whether the slab or the structure carries the door's weight.
- Wind resistance. Closed doors are designed to resist the wind pressure your site can see without jamming.
- Multi-leaf sliding. Leaves stacking to one or both sides, or into door pockets, with no headroom needed.
- Designed per opening. Each door engineered around the opening size, structure and site wind exposure.
- Safety systems. Edge protection, photocells, warning lights, sounders and interlocks.
Typical scopes of work
- Fitting a vertical-lift fabric door to a tall vehicle maintenance shed where adjoining buildings take up the side space.
- Adding warning beacons, sounders and photocells to an older powered large-span door as part of a site risk assessment review.
- Installing heavy-duty sectional doors with wind-resistant panels across the frontage of a bus or coach garage.
Who is responsible for door safety at a site in Isleworth?
In England, two sets of duties meet at a powered door. The installer who supplies or motorises it must hand over a door that meets the Supply of Machinery (Safety) Regulations 2008, tested against BS EN 12453 and documented. The business in control of the premises must then maintain it: regulation 5 of the Workplace Regulations 1992 covers maintenance, and regulation 18 requires upward-opening doors to have a device that stops them falling back and powered doors to have features that prevent trapping.
Access, phasing and timing
For busy sites in Greater London the work can be split across visits — preparation and framing first, door installation and commissioning second — so the opening is only out of action for the shortest time.

Questions from businesses in Isleworth
Do you work on hangar door projects with our engineer in Isleworth?
Yes. We coordinate loads, fixings, floor rails and steelwork with your structural engineer and main contractor so the door and the building are designed together, and we agree a programme before manufacture.
Can you refurbish our existing hangar doors in Isleworth?
Often, yes. If the leaves are sound, we renew wheels, guides, drives, cladding and safety devices. Where distortion or corrosion is severe, we explain why replacement may be better value.
Can a large door at our Isleworth site be operated without power?
Most powered large doors include a manual or emergency means of operation for power failures. How it works depends on the door type and size, and we explain it at handover and in the user instructions.
