Cautions
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 groundLow 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 areasPaint 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 costCCA (copper-chrome-arsenate) and ACQ (alkaline copper quaternary) treatment chemicals raise environmental and disposal concerns — treated offcuts require controlled disposal, not general wasteSusceptible 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 cuppingNot BAL-29 compliant as standard cladding — combustible softwood with lower density than hardwood species; additional fire protection measures required in bushfire attack level zones per AS 3959Lower structural contribution than hardwood cladding — 19mm radiata pine battens provide minimal racking resistance; structural engineers may require additional bracing elementsKnots and resin pockets common in standard grades — can bleed through paint finish, requiring shellac-based primer treatment on knots before topcoat applicationPlantation-sourced but certification variable — FSC/PEFC certification not universal across all suppliers; specify certified product to meet Green Star or NCC sustainability requirements
