Question 1

What size F7 roof batten do I need?

Accepted Answer

F7 roof battens are typically supplied in 38×25, 50×38, 50×50, 70×35 and 70×45 mm sections. The correct size for your project depends on the span, spacing and load condition — always confirm against the AS 1684.2 roof batten table for your wind classification.

Question 2

What spacing should I use for F7 roof battens?

Accepted Answer

Roof Battens are typically installed at 450 or 600 or 900 mm centres in Australian residential construction. Wider centres mean larger sections; narrower centres allow smaller sections or longer spans for the same section.

Question 3

Is F7 suitable for roof battens under AS 1684?
