S-5! clamps will not fit on face-fastened trapezoidal rib or corrugated type panels.  While S-5! clamps won't work on thru fastened roofs we do have bracket products for them.  You can find those here: S-5! Brackets The bracket products will also not fit on most “batten” seam type panels, except for the traditional batten seams folded joints, as shown below in green.  Any time there is a folded seam we can usually attach a clamp to it.  A great way to know if we have a product for your roof is to determine what the roof is with our "Clamp to Seam tool"
