01Overview
About Industrial Sectional Overhead Doors
A sectional door is built from horizontal insulated panels hinged together, running on tracks that curve from vertical to horizontal above the opening. When open, the whole door sits flat under the roof — the aperture is completely clear, and so is the wall on either side of it.
Operating method
03Variants
Available configurations
The same product, built for a different job. Where a specification depends on opening dimensions, selected profile, operating duty or site conditions, the final configuration is confirmed during technical assessment.
Standard lift
The default arrangement where there is moderate clear headroom above the opening. The leaf runs up the wall then turns back under the roof.
High lift
Extends the vertical track so the leaf travels further up before turning, freeing usable height beneath the horizontal track. For buildings with generous headroom.
Vertical lift
The leaf stores entirely vertically against the wall. Suits very high internal clearance and keeps the ceiling completely clear.
Low headroom
A second horizontal track lets the door operate where there is very little space between the top of the opening and the structure.
Glazed vision panels
Vision sections in one or more panels, or a full-vision glazed leaf, where daylight or sightlines through the opening matter.
Wicket access door
A pedestrian door built into the leaf, interlocked so the main door only runs when the wicket is closed.

FAQ
Questions we are actually asked
- How much headroom does a sectional door need?
- It depends on the lift configuration, which is chosen from the headroom available rather than the other way round. Standard lift needs the most conventional allowance; low headroom track exists specifically for openings that cannot provide it. The figure is confirmed at survey.
- Can a sectional door be insulated?
- Yes — our published specification is a 40–50 mm PUF-cored aluminium or galvanized steel panel, which gives both thermal and acoustic separation.
- What stops the door falling if a spring breaks?
- A spring-break device arrests the torsion assembly and an anti-fall device arrests the leaf if a lifting cable breaks. Both are part of the door, not options.
- How wide can a sectional door be?
- Our published configurations span up to 10 m. Beyond that the assembly is engineered against the specific opening.
