Spiral Seams Face Different Directions in an Exposed Run
PROCEED WITH CHECKSFast answer
Verify the project’s exposed-work expectation, then rotate unconnected sections consistently before final fastening and branch layout. Mechanical fit alone may not satisfy the architectural finish.
What to check
- Sight the run from customer and entry views.
- Check seam direction, branch orientation, screw pattern, labels, and hanger alignment.
- Confirm whether the finish standard or mockup controls.
- Correct rotation before taps and supports lock the section in.
Do not
Do not rotate a connected section if doing so twists branches, damages joints, or changes approved fitting orientation.
Ask the foreman
“The exposed spiral run is mechanically aligned, but two seam lines face the sales floor while the rest face up. Does the approved finish or mockup require us to rotate them before final fastening?”
Why it matters
In exposed work, inconsistent seam orientation can make an otherwise sound installation look crooked or unfinished.
