A roller shutter loading bay door is a door made from interlocking horizontal slats, called laths, that coil around a barrel in a box above the opening. Because it rolls up into a compact space, a shutter needs little headroom and no ceiling tracks, which suits older units, low-headroom openings and buildings with cranes, pipes or racking close above the door.
Is this right for your site in Trowbridge?
Unheated stores and trade counters in Trowbridge can suit a single-skin steel shutter, giving a secure dock door at a lower cost than an insulated sectional door. Where a site in Trowbridge is exposed to salt air or regular washdown, aluminium laths or a good powder coat help slow corrosion on the curtain and guides.
Timber yards and builders merchants in Trowbridge handling long loads and heavy forklift traffic can benefit from strong steel shutters that tolerate knocks.
Keeping the dock running is usually the first concern, so we plan around it. After a free survey of your Trowbridge site and a written quote at a fixed price, we agree when each bay can be released and whether any work should happen out of hours. Specialist installation engineers working under our management then fit the equipment, and we test it and hand over the documentation before the bay goes back into use.
What safety and energy rules apply to roller shutters at a dock?
A dock roller shutter must be protected against falling, must not trap anyone if powered, and in a heated building may need insulated laths to meet energy rules.
- Falling back: the Workplace (Health, Safety and Welfare) Regulations 1992 in Great Britain, and the Northern Ireland regulations of 1993, require upward-opening doors to have a device that stops them falling back. On a shutter this is usually a safety brake or anti-fall device on the barrel.
- Trapping: powered shutters need suitable features to prevent trapping, typically a safety edge and photocells, and a way to open by hand, such as a chain override, where needed.
- Energy: in England, Approved Document L (2021) Volume 2 sets a limiting U-value of 1.3 W/m²K for vehicle access doors in new and replacement work. A single-skin steel shutter will not normally reach that figure. Wales, Scotland and Northern Ireland set their own rules, and we confirm the figure for your nation and project.
Our guide to energy rules for loading bay doors explains U-values in more detail.
Can a roller shutter cope with high winds at an exposed dock?
Yes, if it is specified for the exposure. Wind pushes the curtain inwards or draws it outwards, and on a wide opening that load can pull laths out of their guides or bow the whole curtain.
For exposed docks we typically consider:
- End locks: clips on the ends of the laths that hold the curtain inside the guides under load.
- Deeper guides: give the end locks more to hold on to.
- Heavier gauge or profiled laths: stiffer across wide openings.
- Intermediate wind bars: horizontal reinforcement on very large shutters.
Openings that face open yards, sit at the end of a building or are funnelled between units tend to see the strongest gusts. We note orientation and surroundings at survey and choose a wind-resistant build where it is needed, rather than adding cost to every door on the site.
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?
- Power supply at each bay, including three-phase availability
- Wall and steel structure for door, shelter and bumper fixings
- Age and condition of the equipment already in place
- Scope to convert ground-level doors into docks or add lift tables
- Condition of any existing leveller pit, kerb angles and pit drainage
- Temperature requirements for chilled, frozen or ambient goods
Options to discuss
Single-skin steel shutter
Galvanised or powder-coated steel laths giving a strong, economical door for unheated stores, builders merchants and openings where security matters more than insulation.
Electric operation with safety devices
An external or tubular motor with push-button controls, safety edge, photocells and a hand-chain override for use during a power cut.
Regulations and approvals in England
Sites in Trowbridge fall under the rules for England. Structural changes such as forming a new opening or a dock leveller pit may need Building Regulations approval, and external structures such as loading houses, canopies or new dock approaches can need planning permission from the local planning authority. We check what applies at survey and build any approvals into the plan.
Questions about roller shutter loading bay doors in Trowbridge
Can you work alongside our main contractor on a new build in Trowbridge?
Yes. For new warehouses and fit-outs, we can supply and install the dock package as part of a wider project, working to the main contractor's programme, site rules and permits. We will need drawings, dock levels and the programme, and we coordinate pit details, power supplies and door openings with the relevant trades before installation begins.
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 Trowbridge 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.
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.
Can individual damaged laths be replaced?
Yes, damaged laths can usually be cut out and replaced without changing the whole curtain, provided matching laths are still available. If damage spreads across many laths or the guides are bent, a new curtain is often more economical. Lath repairs are carried out on a chargeable visit with the price agreed first.
What finish options are available?
Most dock shutters are supplied in galvanised steel or powder-coated in a standard colour, with other colours available at extra cost. A hood box over the coil protects it from dust and weather and gives a tidier finish inside. We confirm finish and colour in the written quote.
