Question 1

What size MGP12 ridge beam do I need?

Accepted Answer

MGP12 ridge beams are typically supplied in 190×45, 240×45, 240×63, 300×45 and 240×90 LVL mm sections. The correct size for your project depends on the span, spacing and load condition — always confirm against the AS 1684.2 ridge beam table for your wind classification.

Question 2

What spacing should I use for MGP12 ridge beams?

Accepted Answer

Ridge Beams 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 MGP12 suitable for ridge beams under AS 1684?

Accepted Answer

Yes — MGP12 Pine is recognised under AS 1684 for ridge beams 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.
