Safety law for industrial doors in Wales

Industrial doors in Carmarthen are covered by the same rules as the rest of Great Britain. On handover you should receive user instructions and, for a powered door, the conformity paperwork, because the installer is treated as the manufacturer when they assemble or motorise it. Afterwards, keeping the door in efficient working order is the occupier's job under the Workplace Regulations 1992 and PUWER 1998, which in practice means regular servicing and a written log.

How the work is organised

Most installations in Carmarthen 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 work on hangar door projects with our engineer in Carmarthen?

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 a large door at our Carmarthen 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.

Which hangar door type would suit our building in Carmarthen?

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.
