Start fastening the screws on the lower edge purlin (End-lap), through every other
corrugation crest (1).
Fasten screws at the internal purlins, through every third corrugation crest, starting at
the same side (2).
Fasten screws at the upper edge purlin, through every other corrugation crest, starting
