Question 1

What size Treated Pine lintel do I need?

Accepted Answer

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

Question 2

What spacing should I use for Treated Pine lintels?

Accepted Answer

Lintels are typically installed at 600 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 Treated Pine suitable for lintels under AS 1684?

Accepted Answer

Yes — Treated Pine is recognised under AS 1684 for lintels 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.
