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.
Why do sites in County Antrim choose this?
Yards that are open to the weather in County Antrim may need a wind-reinforced build, because a standard internal high-speed door is not designed for gusts at an external opening. Busy cross-dock and parcel operations in County Antrim can use a high-speed door behind the main dock door to keep traffic flowing while limiting the time the bay stands open.
Manufacturers around County Antrim moving work in progress between production and dispatch can use high-speed doors to stop dust and draughts crossing departments.
We never ask you to commit before you have a fixed price. A free survey at your County Antrim site comes first, followed by a written quote. When the order goes ahead, we plan the installation around your operation, book any out-of-hours working you need and manage the specialist installation engineers on site. The job ends with a full test, a run-through for the people who will use the equipment and a set of handover documents.
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.
Should a high-speed door replace our strip curtain or work alongside our dock door?
At very busy openings a high-speed door often replaces a strip curtain, and at external docks it usually works alongside a slower insulated door rather than replacing it.
Strip curtains are inexpensive, but they slow forklifts, scratch quickly and can hide a pedestrian on the other side. A high-speed door clears the opening fully, closes again within seconds and keeps a clear view through its vision panels. See PVC strip curtains if you are weighing up the two.
At external docks, a common arrangement is:
- an insulated sectional door on the outside for security and closing at night,
- a high-speed door just inside it for daytime traffic,
- an interlock so the high-speed door only runs when the outer door is open.
This pairing keeps the building secure out of hours while cutting the time the opening stands open during the working day.

Which rules apply in Northern Ireland?
Northern Ireland has its own system. Structural alterations at a site in County Antrim, such as a new opening or dock pit, may need building control approval from the council, and external structures such as loading houses or canopies can need planning permission through the council planning service. We check what applies at survey.
Questions
How long does installation take at a site in County Antrim?
It depends on the equipment, the number of bays, the condition of the dock and whether any building or electrical work is needed. We agree a programme with you after the survey, setting out which bays are out of use and when. Larger jobs are usually phased so that part of the dock stays open, and out-of-hours working can be arranged.
Is the site survey in County Antrim 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.
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.
Is a high-speed door secure enough to be the only door at a dock?
Usually not on an external dock. Fabric curtains are designed for speed and draught control rather than security, so most sites keep an insulated sectional door or shutter on the outside for closing at night. Some rigid high-speed designs give more security, and we can discuss them where a single door is needed.
