SYSTEM 04.01 · SAWTOOTH CONFIGURATION
ST-960: 9.6 m sawtooth with polycarbonate support.
Reference 9.6 m sawtooth: steel frame, vertical glazing face, purlins set to the PC sheet span table.
The 9.6 m sawtooth is the most quoted PC configuration because it matches a standard 4 m bay and a standard multi-wall sheet width. The vertical face is framed separately; that frame is what the glazing contractor fixes to, so its straightness is inspected.

One design question to settle early
Snow drift against the vertical glazing face can govern the roof beam. Ask your engineer before the purlin layout is frozen — it is cheaper to change a drawing than a punched profile.
