Town: Welwyn Garden City
Postcode district: AL8
Area: Hertfordshire
Survey: Free for new installations

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.
Folding leaves. Bi-folding leaves stack neatly where side wall space is limited.
Wide spans. Very wide openings are handled by adding leaves, so width is rarely a limit.
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.

What this work can involve

Renewing seized trolleys and a distorted overhead track on large sliding doors to a vehicle shed.
Automating a pair of heavy bi-parting sliding doors with a drive motor, safety edges and photocells.
Adding a steel support beam and top-hung track so a sliding door leaves the floor flush for forklifts.

Powered door rules that apply in Welwyn Garden City

Welwyn Garden City is in England, 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.

Planning the work around your site

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.

Your questions about sliding and folding industrial doors

Can our existing sliding doors in Welwyn Garden City 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.

How long does it take to fit sliding doors in Welwyn Garden City?

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.

Will a sliding door fit our building in Welwyn Garden City?

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.
