Options for sliding and folding industrial doors in Derry

Folding leaves. Bi-folding leaves stack neatly where side wall space is limited.
Wicket doors. Pass doors built into a leaf so staff need not open the whole door.
No headroom needed. Leaves move sideways, so nothing coils above or runs under the roof.
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.

Typical scopes of work

Renewing seized trolleys and a distorted overhead track on large sliding doors to a vehicle shed.
Replacing worn timber sliding doors on a storage building with steel-framed bottom-rolling doors and a wicket door.
Automating a pair of heavy bi-parting sliding doors with a drive motor, safety edges and photocells.

Powered door rules in Northern Ireland

Derry is in Northern Ireland, where workplace safety is regulated by HSENI under the Health and Safety at Work (Northern Ireland) Order 1978. The Workplace (Health, Safety and Welfare) Regulations (Northern Ireland) 1993 and PUWER (Northern Ireland) 1999 require occupiers to keep powered doors safe and maintained. Under the Windsor Framework, EU machinery rules and CE marking continue to apply to powered doors placed on the market here, with the EU Machinery Regulation 2023/1230 applying from 20 January 2027.

Access, phasing and timing

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.

Sliding and folding industrial doors in Derry: your questions

Can our existing sliding doors in Derry 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.

Which is better for our Derry site, top-hung or bottom-rolling?

Top-hung keeps the floor flush but needs a strong structure overhead. Bottom-rolling suits lighter buildings but needs a clean, protected floor rail. We recommend one after checking both on survey.

Will a sliding door fit our building in Derry?

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.
