Options that matter on site
- Robust build. Steel-framed leaves with steel, panel or timber cladding.
- Insulated options. Leaves can be filled with insulated panels and sealed along their edges to cut heat loss.
- Wide spans. Openings of almost any width split into as many leaves as needed.
- Folding leaves. Where there is little wall either side, folding leaves concertina into a compact stack.
- Electric operation. Motor drives with safety edges, photocells and guarding where needed.
Jobs we can carry out
- Supplying insulated sliding leaves with edge seals for a converted building now used as a heated workshop.
- Installing telescopic sliding doors where the wall space to one side is limited by an adjoining structure.
- Fitting bi-folding doors to a maintenance workshop where overhead gantry cranes rule out a roller shutter or sectional door.
Who is responsible for door safety at a site in Harpenden?
In England, two sets of duties meet at a powered door. The installer who supplies or motorises it must hand over a door that meets the Supply of Machinery (Safety) Regulations 2008, tested against BS EN 12453 and documented. The business in control of the premises must then maintain it: regulation 5 of the Workplace Regulations 1992 covers maintenance, and regulation 18 requires upward-opening doors to have a device that stops them falling back and powered doors to have features that prevent trapping.
Planning the work around your site
Electrical work is the part that most often delays a job. If a new or converted door needs a supply, we confirm the motor's requirement at quote stage so your electrician can provide an isolator in the right place before installation day.
