Fixing Arrangement
Lift sheets onto roof supports with rib up and all with overlapping ribs (female) facing towards starting edge. To commence fixing place the first sheet in position with the female rib in line with other building elements and fasten as recommended. Lap the femal rib (with turned-out bottom edge) of the first sheet and insert recommended side lap fasteners to hold the lap firmly in place before fastening the second sheet to supports. Follow the second sheet procedure for subsequent sheets.
