7.2 Roof Sheet Span Information
The roof sheet support spacing for the various profiles are listed in the typical span information of the manufacturer’s product literature. This information varies depending on whether it is an end span, internal span or overhang.
The typical span charts are based on the ability of sheeting to withstand the wind loads specified in AS/NZS 1562.1 and the NCC. All sheeting is to be fixed to each and every roof support unless otherwise approved by a structural engineer

Flashing Type: Flashing edge to material other than metal cladding (e.g barge flushing edge fixed to concrete wall)
Faster Spacing:
Non-cyclonic wine regions: At the same or less spacing as the fastener spacing on the other flashing surface
Cyclonic wind regions:
At not more than 500mm centres.
