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 Gloucestershire?
Landlords preparing an industrial unit in Gloucestershire for a new tenant may choose to replace tired dock doors so the building is ready to trade from day one. For distribution sites in Gloucestershire with heavy daily trailer traffic, an electric sectional door with photocells keeps the bay moving without staff hauling on a chain.
Our survey for a site in Gloucestershire follows the same approach as anywhere else: measure the opening, check headroom and services, then quote a fixed price.
If you are planning sectional loading bay doors for a site in Gloucestershire, expect four stages. A free survey and fixed written quote come first. We then agree a programme with you, including any out-of-hours work. Specialist installation engineers carry out the installation under our management, with us as your single point of contact. Finally, the equipment is tested, your staff are shown how it works and everything is handed over with its documentation.
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.
Which track type suits my dock: standard, high-lift or vertical lift?
The right track depends on how much headroom sits above the opening and what is in it. Standard lift track turns the door through a tight radius so it parks just under the ceiling, and suits units with limited space above the lintel.
- Standard lift: needs the least headroom; the open door rests horizontally close to the head of the opening.
- High-lift: the door travels further up the wall before turning, keeping it above lighting, sprinkler pipes or overhead conveyors and away from forklift masts.
- Vertical lift: the door runs straight up the wall and never turns, which suits tall buildings with racking or cranes close to the opening.
- Low headroom: a special track arrangement for openings with very little space above, often found in older units.
We measure headroom, side room and back room at survey and check where lights, ducts and pipework run, because a door that clashes with services cannot open fully. Our door types guide compares sectional doors with shutters and high-speed doors.

What do the rules in England mean for the work?
Sites in Gloucestershire 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
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 Gloucestershire, 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.
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 Gloucestershire 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 is a sectional loading bay door locked?
A manual sectional door is usually locked with a slide bolt or shoot bolt on the inside, while an electric door is held closed by its operator. Because dock doors are secured from inside the building, extra locks are not often needed, but we can add bolts or a locking operator where security is a priority.
Can a manual sectional door be motorised later?
Often yes, if the door is sound and correctly balanced. An operator is fitted to the spring shaft or a trolley drive is fixed to the ceiling, and the door gets a safety edge and photocells at the same time. We check spring condition and balance first, because a motor should never be used to make up for a badly balanced door.
