A bi-folding security gate is made of hinged leaves of vertical bars that fold against each other as they slide along a top track. It covers wide openings like a retractable grille but folds into fewer, flatter panels with no scissor lattice.
What you can specify
- Black, anthracite and RAL colours
- Top-hung on a heavy track with bottom guides
- Mesh or solid infill panels on request
- Suits openings from a single door width to several metres
- Fold to one or both sides

London's buildings range from Victorian and Edwardian terraces and mansion blocks to post-war estates, with long high streets of ground-floor shops below flats.
This type of grille suits:
- Restaurant and bar frontages
- Garden room and orangery openings
- Wide internal openings
- Loading doors and goods-in
Questions we will ask at the survey
Floor guide
A bottom guide keeps the leaves aligned. Recessed guides keep the floor flush.
Look
Bi-folds read as a screen rather than a lattice, which suits modern interiors.
Planning and safety in England
Grilles inside the glass
A grille fitted inside the glass does not normally need planning permission, because it does not materially change how the building looks from outside. If the building is listed, listed building consent may still be needed.
Listed buildings and conservation areas
Listed buildings need listed building consent for works that affect their character, which can include internal grilles and their fixings. In conservation areas, councils look closely at anything fitted to the outside. We recommend speaking to the council's conservation officer before ordering.

Bi-folding security gates in Harrow: questions
Do you cover Wembley as well as Harrow?
Yes. As well as Harrow, we can arrange surveys in nearby Wembley, Northolt and Greenford, and elsewhere in Greater London.
Can a bi-fold gate go outside?
Yes, with galvanised steel and an external-grade track, though most are fitted inside.
What is the difference between a bi-fold gate and a retractable grille?
A retractable grille uses a scissor lattice that concertinas; a bi-fold gate uses rigid hinged leaves that fold flat. Bi-folds look more architectural; retractables fold into a narrower stack.
How wide can a bi-fold gate be?
From a single doorway up to several metres, split to fold both ways on wider openings.
