Question 1

What size Treated Pine bearer do I need?

Accepted Answer

Treated Pine bearers 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 bearer table for your wind classification.

Question 2

What spacing should I use for Treated Pine bearers?

Accepted Answer

Bearers are typically installed at 450 or 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 bearers under AS 1684?
