High-speed dock doors, in short

A high-speed dock door is a power-operated door with a flexible PVC fabric curtain that opens and closes much faster than a conventional sectional door or shutter, usually driven by a frequency-controlled motor. Many versions use a self-repairing curtain or breakaway bottom bar, so a forklift strike pushes the curtain out of its guides instead of wrecking it, and the door re-engages itself on the next cycle.

What should sites in Trowbridge consider?

Whether your site in Trowbridge is a new build or an older unit, we survey the opening, traffic and power before recommending any high-speed door. Where a goods-in area in Trowbridge borders a chilled zone, a fast fabric door helps hold the temperature line without slowing forklift movements between the two.

Yards that are open to the weather in Trowbridge may need a wind-reinforced build, because a standard internal high-speed door is not designed for gusts at an external opening.

We do not give a fixed price without seeing the site. A free survey in Trowbridge lets us check the details that affect the job, and the written quote that follows is a fixed price for the agreed scope. We plan the work around your operation, arrange out-of-hours access if you need it and manage specialist installation engineers throughout. Handover includes testing, a demonstration and the paperwork you need for your records.

Can a high-speed door be used on an external dock opening?

Yes, provided it is specified for the wind and weather the opening faces. Many high-speed doors are designed for internal openings, so an external dock door needs a reinforced build.

  • Wind resistance: external doors use stronger curtains, horizontal wind bars or tensioned belts, and deeper side guides so the curtain stays put in gusts.
  • Insulation: a double-skin curtain reduces heat loss, though fabric does not insulate as well as a thick sectional door.
  • Security: fabric doors are not security doors, so many sites keep a sectional door or shutter outside for closing at night.
  • Impact protection: a self-repairing curtain re-engages after a knock, which matters at a busy dock.

For openings that are mainly internal, such as between goods-in and a chilled zone, a lighter single-skin door with vision panels is usually enough. We match the build to the exposure at survey.

What does a high-speed dock door cost, and why does the price vary so much?

A high-speed dock door typically costs £6,500 to £14,500 per door, excluding VAT, supply and fit. The range is wide because each door is built to order, and an internal door between two zones is a very different product from one facing an exposed yard.

The main things that move the price are:

  • Size and wind exposure: large external openings need reinforced curtains, wind bars or belts and heavier side frames.
  • Curtain type: single-skin fabric costs less than an insulated double-skin curtain.
  • Self-repair and breakaway features: worth paying for wherever forklifts pass through.
  • Activation: radar, induction loops or pull cords, and how many control points are needed.
  • Interlocks: links to an outer door, a leveller or traffic lights.
  • Site works: power supply, removing an old door or strip curtain, and access equipment.

Our loading bay costs guide sets these figures alongside other dock equipment. After a free site survey you receive a fixed written price.

  • Traffic routes for vehicles and separation of pedestrians
  • Escape routes and pedestrian doors close to the bay
  • Wall and steel structure for door, shelter and bumper fixings
  • Clear opening width and height for each door

Options to discuss

Insulated double-skin curtain

Two layers of fabric with an air gap or insulation between them, reducing heat or chill loss at openings between temperature zones or at external docks.

Self-repairing curtain

If a forklift strikes the door, the curtain or bottom bar pulls out of the side guides without damage and re-engages on the next cycle, keeping the opening in use.

What do the rules in England mean for the work?

Workplace safety in England is regulated by HSE. For a loading bay in Trowbridge, that means doors meeting regulation 18 of the Workplace (Health, Safety and Welfare) Regulations 1992, equipment maintained under PUWER and suitable safeguards against vehicles driving away too early. We check what applies at survey and design the bay accordingly.

Questions about high-speed dock doors in Trowbridge

Do you remove and dispose of the old equipment?

Yes, where it is part of the scope. When we replace doors, levellers, shelters or seals at a site in Trowbridge, removal and disposal of the old equipment can be included and is itemised in the quote, so it is clear what is covered. If anything should be kept, such as a frame or motor that is still serviceable, we agree that at survey.

Will you deal with building control and planning for a project in Trowbridge?

We check at survey whether the work is likely to need approval. Forming a new opening or dock pit may need Building Regulations approval, a building warrant or building control approval, depending on the nation, and external structures such as loading houses can need planning permission. Where approval is needed, we explain what is involved, work with your designer or agent, and build it into the programme.

Is the site survey in Trowbridge free?

Yes. For new installations, replacements, upgrades, conversions and complete bays, the site survey and written quote are free and come with no obligation. The survey lets us measure the openings, check the dock and structure, and understand how the bay is used, so the quote reflects your site. Repair and servicing visits are different: they are chargeable, with the price agreed before anyone attends.

What happens if a forklift hits a high-speed door?

On a door with a self-repairing curtain or breakaway bottom bar, the curtain is pushed out of its guides and re-engages on the next cycle, usually with no repair needed. Repeated hard impacts still wear the curtain and guides, so knocks should be logged and checked at the next service visit.

Can a high-speed door be opened in a power cut?

Yes, a high-speed door should have a manual release, crank or counterbalance so it can be opened if the power fails. This reflects the workplace rule that powered doors must be operable by hand where needed for health or safety, unless they open automatically on power failure.
