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.
How does this suit sites in Cornwall?
Where a site in Cornwall is exposed to salt air or regular washdown, aluminium laths or a good powder coat help slow corrosion on the curtain and guides. Every shutter we quote for a building in Cornwall starts with a survey of the opening, the space above it and how often the door will run.
Landlords refurbishing a vacant unit in Cornwall may choose an insulated shutter where headroom is tight but a future tenant is likely to heat the building.
Here is what happens after you contact us about a site in Cornwall. We arrange a free survey, measure up and send a fixed written quote. If you go ahead, we manage the whole job, including ordering, delivery and coordination with your site team. Specialist installation engineers working under our management do the fitting, at times built around your loading schedule, with out-of-hours work by arrangement. Testing and handover documents close the job.
Which lath should I choose: single skin, insulated or aluminium?
Choose single-skin steel for unheated buildings where cost and strength matter most, insulated laths where the building is heated, and aluminium where weight or corrosion is the main concern.
- Single-skin steel: strong and economical, ideal for unheated stores, trade counters and secure external openings, but it offers little insulation.
- Insulated steel laths: twin-skin laths filled with foam improve thermal performance and reduce noise. The coil is larger, so the box above the opening is bigger.
- Aluminium laths: lighter and corrosion resistant, useful in coastal or washdown environments, and easier on the motor at large openings.
- Perforated or punched laths: let light and air through while keeping the opening secure, better suited to internal cages than external docks.
Lath gauge and profile matter too. Heavier gauges resist forklift knocks and wind better, and we specify them for wide or exposed openings.
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.

Planning, building control and safety law in England
Workplace safety in England is regulated by HSE.

We check what applies at survey and design the bay accordingly.
Questions
Do you cover Cornwall for roller shutter loading bay doors?
Yes. We take on roller shutter loading bay doors for businesses in Cornwall and across Cornwall. 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.
How long does installation take at a site in Cornwall?
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.
Can an existing manual shutter be motorised?
Often yes. If the barrel, end plates and curtain are in good condition, an external or tubular motor can be added with controls and safety devices. Older or heavier shutters sometimes need a stronger barrel first, and a badly worn curtain is usually better replaced at the same time.
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.
