What we fit in Barnet
- Safety systems. Edge protection, photocells, warning lights, sounders and interlocks.
- Vertical-lift fabric. Tall openings with little side space can use a fabric door that lifts and folds into a compact stack.
- Wind resistance. Closed doors are designed to resist the wind pressure your site can see without jamming.
- Refurbishment. Sound but tired doors can be brought back with new running gear, drives and safety devices.
- Drives and controls. Electric drives per leaf or central, with manual or emergency operation.
Examples of work we can quote for
- Adding warning beacons, sounders and photocells to an older powered large-span door as part of a site risk assessment review.
- Refurbishing manual large-span sliding doors with new bottom wheels, top guides and an electric drive unit on each leaf.
- Surveying and specifying a very wide sliding or folding door for a building that houses large plant and machinery.
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.
Access, phasing and timing
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.
