What we fit in Hertfordshire

Load path. We decide with your structural engineer whether the slab or the structure carries the door's weight.
Vertical-lift fabric. Tall openings with little side space can use a fabric door that lifts and folds into a compact stack.
Drives and controls. Electric drives per leaf or central, with manual or emergency operation.
Refurbishment. Older hangar doors renewed with new wheels, guides, drives and cladding.
Safety systems. Edge protection, photocells, warning lights, sounders and interlocks.

Typical scopes of work

Surveying and specifying a very wide sliding or folding door for a building that houses large plant and machinery.
Refurbishing manual large-span sliding doors with new bottom wheels, top guides and an electric drive unit on each leaf.
Recladding the leaves of a large sliding door with a corrosion-resistant finish suited to an exposed site.

Powered door rules that apply in Hertfordshire

Hertfordshire is in England, 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.

Access, phasing and timing

Most installations in Hertfordshire can be phased so part of the site keeps working. We agree access routes, exclusion zones and any temporary security with you before the team arrives, and can work early mornings, evenings or weekends where the business needs it.

Frequently asked questions

Do you service large doors across the East of England?

Yes. We service and repair hangar and large-span doors across the East of England, including running gear, drives, controls and safety devices. Service and repair visits are chargeable and quoted before work starts.

Which hangar door type would suit our building in Hertfordshire?

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.

Can you refurbish our existing hangar doors in Hertfordshire?

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.
