Options that matter on site

  • Wind resistance. Closed doors are designed to resist the wind pressure your site can see without jamming.
  • Refurbishment. Sound but tired doors can be brought back with new running gear, drives and safety devices.
  • Vertical-lift fabric. Reinforced fabric curtains with wind bars that fold up beneath the lintel.
  • Designed per opening. Each door engineered around the opening size, structure and site wind exposure.
  • Drives and controls. Electric drives per leaf or central, with manual or emergency operation.

What this work can involve

  • Recladding the leaves of a large sliding door with a corrosion-resistant finish suited to an exposed site.
  • Coordinating floor rail installation with the groundworks contractor before new large-span door leaves arrive on site.
  • Fitting a vertical-lift fabric door to a tall vehicle maintenance shed where adjoining buildings take up the side space.

Who is responsible for door safety at a site in County Londonderry?

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.

How the work is organised

Downtime matters on a working site, so the programme is set around your shifts. For a single door the opening is usually needed for a day; multi-door jobs are done one bay at a time so deliveries keep moving.
