Can anyone point me in the right direction to find recommended details on installation of steel sheet roofing. Specifically, I am trying to find out if plywood sheathing is required or recommended, a condensation barrier and the size of the purlins.
Thanks for any suggestions

In my experience there are a thousand variables.
What are you building? Home, barn, garage, heated shop, or?
When you say "sheet steel" do you mean the "raised rib" type, standing seam, corrugated, or?
Something is what it does.
Spec's differ from manufacturer to manufacturer. Installation manuals are available online from numerous manufacturers.
on mine it was plywood 5/8 no waffer board, tarpaper then steel
