Question 1

What size Hardwood roof batten do I need?

Accepted Answer

Hardwood 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 Hardwood 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 Hardwood suitable for roof battens under AS 1684?

Accepted Answer

Yes — Australian Hardwood is recognised under AS 1684 for roof battens in residential construction. Wind classification, load condition and span all affect the specific section size needed; always size against the official AS 1684.2 (non-cyclonic) or AS 1684.3 (cyclonic) table.
