A sectional loading bay door is an overhead door made from horizontal insulated steel panels hinged together, which run up on rollers in side tracks and park beneath the ceiling or up the wall when open. Panels are commonly 40 to 80 mm thick, so the door seals and insulates better than a single-skin shutter, and it can be operated by hand chain, push-up or electric motor.
Is this right for your site in Lancing?
For distribution sites in Lancing with heavy daily trailer traffic, an electric sectional door with photocells keeps the bay moving without staff hauling on a chain. Warehouses across Lancing that still rely on single-skin shutters may switch to insulated sectional doors when heating costs or cold goods-in areas become a problem.
Our survey for a site in Lancing follows the same approach as anywhere else: measure the opening, check headroom and services, then quote a fixed price.
It starts with a free site survey in Lancing, 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.
Do sectional loading bay doors have to meet energy and safety rules?
Yes. New and replacement sectional loading bay doors fall under building energy rules and workplace safety law, and the detail differs between the four nations.
- Energy: in England, Approved Document L (2021) Volume 2 sets a limiting U-value of 1.3 W/m²K for vehicle access and similar large doors in new and replacement work. Wales, Scotland and Northern Ireland each have their own energy rules, and we confirm the figure that applies to your nation and project.
- Falling back: the Workplace (Health, Safety and Welfare) Regulations 1992 in Great Britain, and the Workplace (Health, Safety and Welfare) Regulations (Northern Ireland) 1993, require upward-opening doors to have a device that stops them falling back. On a sectional door that usually means spring break and cable break protection.
- Product standard: BS EN 13241 is the product standard for industrial doors, and powered doors are also assessed against BS EN 12453 for safety in use.
- Marking: a powered door in Great Britain may be UKCA or CE marked, while in Northern Ireland it is the CE mark, or CE with UKNI, that applies.
What happens on site when a sectional dock door is installed?
Fitting a sectional dock door often takes around a day per opening once the door is on site, though very large doors or awkward fixings take longer. The bay is out of use while the work is under way.
A typical installation runs like this:
- The old door, if there is one, is taken down and removed from site.
- Steel angles or packers are fixed to the opening so the tracks run true.
- Tracks, springs and panels are assembled and the door is balanced.
- The operator, safety edge, photocells and controls are fitted and wired.
- The door is tested, adjusted and handed over.
Before we arrive you will need a clear area inside the opening for access equipment and the bay taken out of service. Electric doors also need a suitable isolated power supply near the door head, single or three-phase depending on the operator, which we confirm in the quote. On multi-door sites we work bay by bay so the rest of the dock keeps running.
The same published guide range applies across England; access, out-of-hours working and site conditions are confirmed at the free survey.
Survey checklist for your dock
- Access for deliveries, cranes or lifting equipment during installation
- Yard gradient and the slope of the approach to the dock
- Drainage on recessed or sloping dock approaches
- Condition of any existing leveller pit, kerb angles and pit drainage
- Forklift and pallet truck loads crossing the leveller platform
- Escape routes and pedestrian doors close to the bay
Options to discuss
Thicker insulated panels
Panels at the upper end of the common 40 to 80 mm range improve insulation for heated warehouses and temperature-controlled goods-in areas.
Electric operator
A shaft-mounted or trolley operator with push-button controls, safety edge and photocells. Suits busy bays and can be interlocked with levellers, shelters and traffic lights.
Regulations and approvals in England
In England, Approved Document L (2021) sets a limiting U-value of 1.3 W/m²K for vehicle access and similar large doors in new and replacement work. That shapes door specification for sites in Lancing, so we confirm the requirement for your project and check what applies at survey before recommending a door.
Questions about sectional loading bay doors in Lancing
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 Lancing, 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.
Is the site survey in Lancing 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.
How long does installation take at a site in Lancing?
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.
Will the bay be out of action for long?
Usually only on installation day. The door is made to order before we book the fitting, so the old door stays in use until the new one is ready to go in. On sites with several bays we fit one opening at a time, keeping the rest of the dock running.
Can a sectional dock door be made to fit our existing opening?
Yes, sectional doors are made to measure, so they can be fitted to most existing dock openings. We measure the structural opening, headroom and side room at survey and choose a track to suit. Uneven reveals or a low lintel can usually be dealt with using packers, steel angles or a low-headroom track rather than building work.
