Options that matter on site
- Designed per opening. Each door engineered around the opening size, structure and site wind exposure.
- Load path. Bottom-rolling on floor rails or top-hung from the structure, agreed with your engineer.
- Safety systems. Large doors move a lot of mass, so warning and detection devices are built in from the start.
- Wind resistance. Leaves, guides and fixings designed for the wind load on the closed door.
- Refurbishment. Sound but tired doors can be brought back with new running gear, drives and safety devices.
Typical scopes of work
- Installing heavy-duty sectional doors with wind-resistant panels across the frontage of a bus or coach garage.
- Coordinating floor rail installation with the groundworks contractor before new large-span door leaves arrive on site.
- Adding warning beacons, sounders and photocells to an older powered large-span door as part of a site risk assessment review.
Who is responsible for door safety at a site in Derry?
In Northern Ireland, the business in control of the premises must keep doors and gates safe under the Workplace Regulations (Northern Ireland) 1993 and maintain work equipment under PUWER (Northern Ireland) 1999, with HSENI as the regulator. The installer who supplies or motorises a door hands over the conformity documents and user instructions; CE marking remains the relevant mark for machinery here.
Planning the work around your site
For busy sites in County Londonderry 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.

Frequently asked questions
Which hangar door type would suit our building in Derry?
It depends on headroom, side space, structure and how often the door moves. Sliding doors need side space, vertical-lift fabric doors need headroom, and large sectional doors suit big but not extreme openings. We recommend after survey.
Do you work on hangar door projects with our engineer in Derry?
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.
Do you service large doors across County Londonderry?
Yes. We service and repair hangar and large-span doors across County Londonderry, including running gear, drives, controls and safety devices. Service and repair visits are chargeable and quoted before work starts.
