Short answer: Aluminum bifold doors are a complete frame, glass and hardware system. Compare the panel pairs, profile, glass, rollers, hinges, threshold, drainage, fixing and installation scope rather than choosing by finish alone.
Measure the finished opening and show how the panels fold and park. Mark the first-opening panel, handle, furniture, steps and clear route. For a renovation, inspect the header, sill, floor and substrate; for new construction, coordinate the structural opening and finishes.
Request a drawing with the closed elevation and the folded plan. The drawing should show which dimensions are measured and which are assumptions for budgeting.
Send every supplier the same opening schedule, finish direction and quantity. Compare clear opening, panel order, glass, hardware, threshold, lead time, packing, installation exclusions and service responsibility. A cheaper price may omit structural preparation or final adjustment.
At handover, operate each pair, check lock engagement, inspect gaps and seals and record how rollers and hinges are adjusted. Keep the approved drawing and care sheet with the project records.
Aluminum profiles are only one part of the door. Check the glass, panel weight, hinges, rollers, locks, threshold and fixing detail as a single system. For a renovation, photograph the opening before the frame arrives and record any substrate repair. At handover, confirm the panel order, clear passage, lock engagement, seals, drainage and adjustment points. Keep the approved drawing and care sheet with the finish reference so a later replacement follows the original specification.
Compare the proposed aluminum system with the actual opening and panel weight, not with a generic profile image. Confirm the finish, glass, rollers, hinges, locks, seals and fixing detail in the submittal. At handover, test each pair, record the clear passage, inspect the threshold and explain how to clean and adjust the moving parts. A clear service record protects both the finish and the operation of the door.
Check the profile, glass, panel weight and hardware as one assembly. At handover, demonstrate the pair sequence, lock engagement and cleaning routine. Keep the approved submittal and adjustment notes available for future roller or hinge service.
No. Tracks, rollers, hinges, seals and drainage need inspection and cleaning.
Possibly, but panel weight and hardware limits must be checked for the actual system and opening.
Opening dimensions, panel pairs, handing, glass, hardware, threshold, drainage and installation scope.
