Treated Pine pergola beams are typically supplied in 140×45, 190×45, 240×45, 190×90 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 pergola beam table for your wind classification.

Question 2

What spacing should I use for Treated Pine pergola beams?

Pergola Beams are typically installed at 900 or 1200 or 1800 or 2400 mm centres in Australian residential construction. Wider centres mean larger sections; narrower centres allow smaller sections or longer spans for the same section.
