Options that matter on site
- Wide spans. Very wide openings are handled by adding leaves, so width is rarely a limit.
- Folding leaves. Bi-folding leaves stack neatly where side wall space is limited.
- Top-hung or bottom-rolling. Weight carried overhead or on a floor rail, chosen to suit the structure.
- Insulated options. Leaves can be filled with insulated panels and sealed along their edges to cut heat loss.
- Wicket doors. Pass doors built into a leaf so staff need not open the whole door.
Jobs we can carry out
- Replacing a damaged floor rail and guide wheels on a bottom-rolling door struck by a vehicle.
- Automating a pair of heavy bi-parting sliding doors with a drive motor, safety edges and photocells.
- Fitting bi-folding doors to a maintenance workshop where overhead gantry cranes rule out a roller shutter or sectional door.
Powered door rules that apply in Caernarfon
Caernarfon is in Wales, 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
For busy sites in Gwynedd the work can be split across visits — preparation and framing first, door installation and commissioning second — so the opening is only out of action for the shortest time.

Frequently asked questions
How long does it take to fit sliding doors in Caernarfon?
A pair of manual sliding doors on a sound structure is usually fitted in a day or two. Large folding doors, electric operation and new steelwork add time, which we set out with your quote.
Do you fit sliding doors on farm buildings around Gwynedd?
Yes. We supply and fit steel sliding doors on agricultural buildings across Gwynedd, including timber-clad leaves, bottom-rolling gear for lightweight portal frames and wicket doors so staff and livestock handlers can get in without opening the main leaves.
Can our existing sliding doors in Caernarfon be motorised?
Often, if the leaves and track are in good condition. We assess the doors, fit a drive and the safety devices needed, and take on the conformity responsibilities that come with converting a manual door to power.
