Sliding and folding industrial doors in Barnet

Quick answer

We can supply and fit steel sliding and bi-folding doors in Barnet and across Greater London, manual or electric, with insulated or single-skin leaves and wicket doors wherever staff need everyday access.

Town: Barnet
Postcode district: EN5
Area: Greater London
Survey: Free for new installations

What to specify

Insulated options. Insulated panel infill and edge seals for heated buildings.
Robust build. Steel-framed leaves with steel, panel or timber cladding.
Folding leaves. Bi-folding leaves stack neatly where side wall space is limited.
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. Openings of almost any width split into as many leaves as needed.

Typical scopes of work

Replacing a damaged floor rail and guide wheels on a bottom-rolling door struck by a vehicle.
Fitting bi-folding doors to a maintenance workshop where overhead gantry cranes rule out a roller shutter or sectional door.
Installing telescopic sliding doors where the wall space to one side is limited by an adjoining structure.

Who is responsible for door safety at a site in Barnet?

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

Most installations in Barnet can be phased so part of the site keeps working. We agree access routes, exclusion zones and any temporary security with you before the team arrives, and can work early mornings, evenings or weekends where the business needs it.

Questions from businesses in Barnet

Can our existing sliding doors in Barnet 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.

Will a sliding door fit our building in Barnet?

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.

Which is better for our Barnet 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.
