Options for hangar and large-span doors in Dumbarton

Designed per opening. Each door engineered around the opening size, structure and site wind exposure.
Refurbishment. Sound but tired doors can be brought back with new running gear, drives and safety devices.
Multi-leaf sliding. Classic hangar doors with leaves that slide on parallel tracks and stack clear of the opening.
Drives and controls. Electric drives per leaf or central, with manual or emergency operation.
Safety systems. Large doors move a lot of mass, so warning and detection devices are built in from the start.

Examples of work we can quote for

Recladding the leaves of a large sliding door with a corrosion-resistant finish suited to an exposed site.
Refurbishing manual large-span sliding doors with new bottom wheels, top guides and an electric drive unit on each leaf.
Coordinating floor rail installation with the groundworks contractor before new large-span door leaves arrive on site.

Powered door rules that apply in Dumbarton

Dumbarton is in Scotland, where powered industrial doors fall under Great Britain's health and safety law. Whoever makes a door powered — including converting a manual door — usually takes on the manufacturer's duties under the Supply of Machinery (Safety) Regulations 2008: risk assessment, technical file, conformity marking and a Declaration of Conformity. Once it is in use, the employer or occupier must keep it safe under the Workplace (Health, Safety and Welfare) Regulations 1992 and PUWER 1998.

How the work is organised

For busy sites in Renfrewshire and Dunbartonshire 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 Dumbarton?

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.

How much does a hangar door cost in Dumbarton?

Hangar and large-span doors are priced on survey because each is designed for its opening and structure. Typical projects start from around £39,995 ex VAT. After surveying your site in Dumbarton, we confirm a fixed price in writing.

Do you work on hangar door projects with our engineer in Dumbarton?

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.
