The short version
Sliding and folding industrial doors for farms, workshops, vehicle sheds and wide-span buildings in Gwynedd. We survey the opening and the structure, then recommend a top-hung or bottom-rolling layout that suits it.

Options that matter on site
- Insulated options. Insulated panel infill and edge seals for heated buildings.
- Electric operation. Motorised leaves with the safety devices needed to protect against crushing and shearing.
- Wicket doors. A personnel door within a leaf saves sliding the main door for every visit.
- Top-hung or bottom-rolling. We hang the door from above or run it on a floor rail depending on what the building can support.
- Wide spans. Very wide openings are handled by adding leaves, so width is rarely a limit.
What this work can involve
- Replacing a damaged floor rail and guide wheels on a bottom-rolling door struck by a vehicle.
- Adding a steel support beam and top-hung track so a sliding door leaves the floor flush for forklifts.
- Installing telescopic sliding doors where the wall space to one side is limited by an adjoining structure.
Safety law for industrial doors in Wales
Industrial doors in Gwynedd 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
If your premises are leased, check whether the landlord needs to approve the work. We can provide drawings and product data for the landlord or managing agent before the order is placed.

Frequently asked questions
Will a sliding door fit our building in Gwynedd?
It needs wall space to the side for the leaves to slide past, or room for folded leaves to stack. We measure this on survey and choose between sliding, telescopic and folding layouts to suit what is there.
How much do sliding or folding industrial doors cost in Gwynedd?
Our guide price is £5,995 to £24,995 ex VAT, supplied and fitted, depending on size, number of leaves, infill and whether the doors are manual or electric. After a free survey in Gwynedd we confirm the fixed price in writing.
How long does it take to fit sliding doors in Gwynedd?
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.
