Welcome to the Bunnings Workshop community @Ricardo1960. It's sensational to have you join us, and many thanks for your question about rafter spacing.

You'll find maximum support spacings on page nine of this Lysaght roofing installation manual. The support spacing is determined by the type of sheeting you are using, and it's best to consult the manufacturer. For our Lysaght sheeting in custom orb, it's 700mm for the 0.42mm sheets

Please let me know if you have any questions.
