The purlins are held with the metal screwed on from the outside. The 2x6 will allow me to add a little insulation, frame between them with 2x4 before attaching the osb. Everyone I look at that these guys built did not have a problem with sagging and most were not finished on the inside.
Never saw it done this way, which makes me curious about it. As long as you are happy with it, then that's all that matters.
