Question 1

What size LVL hip rafter do I need?

Accepted Answer

LVL hip rafters are typically supplied in 140×45, 190×45, 240×45, 240×63 and 240×90 mm sections. The correct size for your project depends on the span, spacing and load condition — always confirm against the AS 1684.2 hip rafter table for your wind classification.

Question 2

What spacing should I use for LVL hip rafters?

Accepted Answer

Hip Rafters are typically installed at 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 LVL suitable for hip rafters under AS 1684?

Accepted Answer

Yes — LVL (Laminated Veneer Lumber) is recognised under AS 1684 for hip rafters 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.
