A retractable dock shelter is a fabric shelter fixed to the building around a loading bay door, with flexible top and side curtains carried on a sprung or pantograph steel frame. When a trailer reverses in, the frame retracts and the curtains drape against the trailer's sides and roof, closing most of the gap while leaving the full width of the trailer opening clear for loading.
Why do sites in Cornwall choose this?
Shelter sizing for a bay in Cornwall starts with measuring the door and wall and recording the tallest, lowest and widest trailers you receive. Third-party logistics sites in Cornwall receiving trailers from many hauliers usually need a shelter rather than a seal, because widths and heights vary.
Loading staff at a draughty dock in Cornwall notice the difference when the gaps around the trailer are closed, especially through the colder months.
It starts with a free site survey in Cornwall, where we measure the openings, check the dock and talk through how the bay is used. You then receive a fixed written quote. Once you accept, we manage the job: specialist installation engineers carry out the work under our management, planned around your deliveries, and out-of-hours working can be arranged. At handover we test everything with you and leave the documentation.
How do I size a retractable shelter for my trailers?
Size a retractable shelter to the largest trailer you receive, with a projection deep enough for opened trailer doors and the leveller lip, and curtains that still reach the smallest vehicles. The trailer mix sets almost every dimension.
- Width: wider than the trailer, so the side curtains drape along its sides rather than across the opening.
- Height: high enough for the tallest trailers, with a top curtain deep enough to reach the roof of the lowest.
- Projection: deep enough for the rear doors, folded back along the trailer sides, to sit inside the curtains.
- Curtain cut-outs: vertical slits let the side curtains wrap around hinges and rear fittings without tearing.
- Guide stripes: contrasting stripes on the curtains help drivers centre the trailer.
If your fleet is uniform, a seal may give a tighter fit. Our guide to shelters and seals sets out the trade-offs.
Why do trailer door hinges matter when choosing a shelter?
Trailer door hinges matter because the rear doors are opened and folded back along the trailer sides before reversing, and the shelter has to accommodate them. If the shelter is too shallow, the hinges and doors sit outside it, leaving gaps or snagging the curtains.
A shelter handles this better than a seal:
- its side curtains drape over the opened doors and hinges rather than pressing against them,
- the full width of the trailer opening stays clear, because nothing protrudes in front of the trailer's rear frame,
- slit curtains wrap around hinge blocks without tearing.
By contrast, a dock seal presses against the rear of the trailer, so gaps at the hinges can remain, and poorly sized side pads can intrude into the opening. That is why shelters are generally favoured for mixed fleets, where hinge positions and trailer widths vary from one vehicle to the next.

Which rules apply in England?
Powered doors and dock equipment installed in England may carry the UKCA or the CE mark, and doors are covered by the product standard BS EN 13241. We hand over the relevant documentation for each item fitted in Cornwall. Planning and Building Regulations questions are never assumed either way: we check what applies at survey, so you know before work is booked.
Questions
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 Cornwall 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.
What details do you need from us to quote for retractable dock shelters?
To get started, send the site address in Cornwall, 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.
Can I replace just the curtains on an old shelter?
Yes, if the frame and fixings are sound, new top and side curtains can be fitted to an existing shelter, which is often the most economical way to restore it. The frame and springs are checked first, because new curtains on a failing frame will not last. This is handled as a repair, with the visit price agreed beforehand.
Does a dock shelter keep a building warm?
A shelter reduces the draughts and rain entering the dock around a trailer, which helps keep the loading area warmer. It does not seal as closely as a dock seal or inflatable shelter, so for chilled and frozen docks those options are usually preferred.
