Best when…
- organic material benefits
Top advantages
- 01 organic material benefits
Top limitations
- 01 Durability Class 4 (non-durable) per AS 5604 — H3 CCA or ACQ preservative treatment mandatory for all external applications; untreated radiata pine will rot within 2–5 years above ground
- 02 Low density (~500–550 kg/m³) and low Janka hardness (3.2 kN) — softwood prone to denting, gouging, and surface damage; unsuitable for high-traffic or impact-exposed areas
- 03 Paint maintenance cycle every 8–12 years in typical Australian external exposure — repainting on top of failed paint requires full strip-back and re-prime, adding significant lifecycle cost
- 04 CCA (copper-chrome-arsenate) and ACQ (alkaline copper quaternary) treatment chemicals raise environmental and disposal concerns — treated offcuts require controlled disposal, not general waste
- 05 Susceptible to moisture movement without proper site practice — all faces (including back and ends) must be primed before installation per manufacturer requirements to prevent differential absorption and cupping
