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 Letchworth Garden City consider?
Yards that are open to the weather in Letchworth Garden City may need a wind-reinforced build, because a standard internal high-speed door is not designed for gusts at an external opening. Replacing tired strip curtains is one reason a business in Letchworth Garden City might consider a high-speed door, especially where drivers struggle to see through scratched strips.
Manufacturers around Letchworth Garden City moving work in progress between production and dispatch can use high-speed doors to stop dust and draughts crossing departments.
We keep the process simple for sites in Letchworth Garden City. A free survey tells us what the dock needs; a fixed written quote tells you what it will cost and what is included. We then organise the installation, with specialist engineers under our management and a programme agreed around your shifts. Night and weekend work is available by arrangement. Before we leave, the new equipment is tested, demonstrated and handed over with its documentation.
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.
What does a high-speed door installation need from our site?
A high-speed door installation needs a sound opening to fix the side frames to, a suitable power supply near the door, and the opening taken out of use on the day of fitting.
Before we attend, please make sure:
- a dedicated supply with a local isolator is in place near the door head, or is included in our quote,
- the floor at the threshold is level, as the bottom edge needs a consistent landing,
- stock, racking and vehicles are cleared from both sides of the opening,
- your team has agreed where push buttons, pull cords or radar sensors should sit, based on traffic routes.
On site, engineers working under our management fit the frames and drive unit, hang the curtain, wire the control panel and light curtain, then set opening heights and speeds. Where the door sits behind an existing sectional door, we also wire the interlock so the two doors work in sequence.
The same published guide range applies across England; access, out-of-hours working and site conditions are confirmed at the free survey.
What does the free survey cover?
- Drainage on recessed or sloping dock approaches
- Access for deliveries, cranes or lifting equipment during installation
- Power supply at each bay, including three-phase availability
- Headroom above the opening and which track type will suit it
- Working hours, shift patterns and windows for out-of-hours work
- Whether planning, building control or a building warrant may be needed
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.
Planning, building control and safety law in England
Workplace safety in England is regulated by HSE. For a loading bay in Letchworth Garden City, 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 Letchworth Garden City
Do you cover Letchworth Garden City for high-speed dock doors?
Yes. We take on high-speed dock doors for businesses in Letchworth Garden City and across Hertfordshire. We survey the site, provide a fixed written quote and manage the installation, with specialist installation engineers working under our management. Visits are arranged in advance at a time that suits your operation, and the same single contact stays with the job through to handover.
What details do you need from us to quote for high-speed dock doors?
To get started, send the site address in Letchworth Garden City, the number of bays or openings, approximate sizes, and photos of the dock from inside and outside. Tell us what vehicles you load, what goods you handle and any temperature requirements. Drawings help on new builds. We then arrange the free survey and confirm the details before the written quote is issued.
What warranty comes with new loading bay equipment?
New equipment comes with the manufacturer's warranty, which varies by product. Our workmanship terms are set out in writing in the quote for your Letchworth Garden City site, so you can see what is covered before you commit. Check the warranty terms for any servicing conditions, and we can quote for planned maintenance once the installation is complete.
How fast does a high-speed door open?
Many dock and internal high-speed doors open at around 1 to 2 metres per second, so a typical opening clears in a few seconds. Speed depends on the size, the drive and whether the door is built for wind. Closing speed is usually set slower than opening for safety, and both are adjusted at handover.
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.
