What to specify
- Wind resistance. Closed doors are designed to resist the wind pressure your site can see without jamming.
- Drives and controls. Electric drives per leaf or central, with manual or emergency operation.
- Vertical-lift fabric. Reinforced fabric curtains with wind bars that fold up beneath the lintel.
- Load path. We decide with your structural engineer whether the slab or the structure carries the door's weight.
- Designed per opening. Each door engineered around the opening size, structure and site wind exposure.
What this work can involve
- Installing heavy-duty sectional doors with wind-resistant panels across the frontage of a bus or coach garage.
- Adding warning beacons, sounders and photocells to an older powered large-span door as part of a site risk assessment review.
- Surveying and specifying a very wide sliding or folding door for a building that houses large plant and machinery.
Safety law for industrial doors in England
Industrial doors in Potters Bar 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.
Keeping your site running during the work
Where a door is being replaced, the opening has to be made secure at the end of each day. We plan strip-out, any new framing and the new door so the gap is never left open overnight unless you have agreed temporary measures.
