What to specify

Insulated panels. 40 mm PU-insulated steel panels as standard, with thicker thermal panels where heat loss matters.
Safety devices. Spring-break and cable-break protection, safety edges, photocells or light curtains, set up to BS EN 12453.
Vision panels. Glazed rows or full-vision sections bring daylight in and let drivers see the yard.
Wicket doors. Integrated pass doors, including low-threshold versions, for staff access without opening the main door.
Paperwork. You get the manufacturer's Declaration of Performance plus commissioning and test records for your files.

Examples of work we can quote for

Converting a manual chain-operated sectional door to electric operation with a shaft-mounted motor, safety edge and photocells.
Renewing torsion springs and lift cables on a busy loading bay door, with higher-cycle springs where the usage justifies them.
Supplying sectional doors in a RAL colour matched to the existing cladding as part of a unit refurbishment between tenants.

Safety law for industrial doors in England

Industrial doors in Welwyn Garden City are covered by the same rules as the rest of Great Britain. On handover you should receive user instructions and, for a powered door, the conformity paperwork, because the installer is treated as the manufacturer when they assemble or motorise it. Afterwards, keeping the door in efficient working order is the occupier's job under the Workplace Regulations 1992 and PUWER 1998, which in practice means regular servicing and a written log.

Access, phasing and timing

For busy sites in Hertfordshire the work can be split across visits — preparation and framing first, door installation and commissioning second — so the opening is only out of action for the shortest time.

Sectional overhead doors in Welwyn Garden City: your questions

How much is a sectional overhead door in Welwyn Garden City?

Our guide price for an electric, 40 mm insulated sectional door up to about 4 × 4.5 m is £3,495 to £8,495 ex VAT, supplied and fitted. The fixed price for your opening in Welwyn Garden City is confirmed in writing after a free survey.

Will a sectional door reduce heating costs at our Welwyn Garden City premises?

An insulated, well-sealed sectional door loses much less heat than a single-skin shutter, and keeping it closed with fast electric operation helps further. Actual savings depend on your building, heating and how often the door is open.

Do you survey sites in Welwyn Garden City before quoting?

Yes. Surveys for new and replacement doors are free. We measure the opening, headroom and obstructions, check the fixings and power supply, and discuss how the door will be used before we price it.
