Repair of an industrial sectional door in Bussy-Saint-Martin (77), including replacement of the two lower panels and the cables. The work retained the existing installation while renewing the components affected by the fault and making the necessary adjustments before returning it to service.
Shasama Fermetures worked in Bussy-Saint-Martin, Seine-et-Marne (77), to restore an industrial sectional door with damaged components in its lower section and lifting system.
The work involved replacing the two lower panels and the sectional door’s cables, along with checks of the various components, adjustments and operating tests before returning it to service.
What was carried out on site
- Measure the panels and inspect the door components
- Secure the door before dismantling
- Replace the two lower panels and the lifting cables
- Adjust the alignment, guidance and cable tension
- Test opening and closing operations before returning the door to service

From inspection to return to service
This project illustrates the different steps required to restore an industrial sectional door without replacing the entire installation.
Inspect the door and identify the components to replace
Before any work begins, our technicians inspect the overall condition of the sectional door to identify precisely which components are concerned. On this installation, the work required replacement of the two panels in the lower section and the lifting cables. The condition of the rails, fixings and main operating components is also taken into account before work starts.
Secure the installation
The door is secured before dismantling operations. Given the height of the installation and the configuration of the industrial building, our technicians used a lift platform to access the door’s various components under suitable working conditions.
Replace the panels and cables
The two affected lower panels are removed and replaced. The sectional door’s cables are also renewed to restore the lifting system correctly. Particular attention is paid to panel positioning, fixing points and cable routing to ensure regular movement of the closure.
Carry out adjustments and checks
Once the components have been replaced, the entire door is checked: panel alignment, travel in the rails, cable position and tension, behaviour during opening and closing, fixing points and overall regularity of movement. The necessary adjustments are made before the final tests.
Test the door before returning it to service
Several opening and closing cycles are used to check the installation’s operation after repair. The door is checked in different positions to ensure that the panels remain properly guided and that movement is regular before it is returned to service.

Why replace only the damaged components?
An industrial sectional door does not necessarily require complete replacement when a fault or damage occurs.
When the rails, structure and other components remain in working order, a targeted repair can preserve a large part of the existing installation.
On this Bussy-Saint-Martin project, the work therefore focused on the components that genuinely required replacement:
- The two lower panels.
- The lifting cables.
This solution restores the door while retaining the components that remain serviceable.
What to watch for afterwards
After work on the panels and cables of a sectional door, certain signs may indicate that another inspection is needed.
- Irregular movement during opening or closing.
- Door rising or descending unevenly.
- Unusual mechanical noise.
- Cable that appears slack, displaced or incorrectly guided.
- Abnormal rubbing at the rails.
- Visible misalignment between the panels.
- Unusual difficulty during operation.
If any of these symptoms occur, it is preferable not to force the door and to have the installation inspected.
