Fastener Spacing

Fasteners should be of grade and type suitable for the application, installed at spacings required by design loads and manufacturer’s recommendations.

On buildings constructed to NZS 3604, a consistent fixing pattern should be used on all fastener rows; for other buildings, higher fastener density may be required around the periphery. All purlins must be fastened to so that they each contribute to resisting uplift loads. See Maximum Span and Fastener Requirements.

Rivets on flashings should be placed at 50 mm centres.
