Wespine

Wespine’s Untreated structural timber is a naturally aesthetic and durable choice for low‑hazard residential framing or internal structural applications. Each piece undergoes rigorous machine stress grading to Australian Standards (AS 1684 and AS 1720), ensuring consistent strength and reliability. The natural grain is retained, making it ideal for visible applications where appearance matters as much as performance.

Wespine Blue H2F is a lightly treated structural pine designed for termite and European house borer resistance in humidity-exposed but above-ground applications. Designated to hazard class H2F, it uses eco-friendly pyrethroid-based treatment with a distinctive blue tint. It comes with a 25-year warranty (via Koppers Performance Chemicals), does not promote fastener corrosion, and meets the same mechanical stress‑graded standards (MGP‑10 and MGP‑12) as untreated timber.

Premium Green H3 represents Wespine’s top-level treated structural timber, suitable for higher hazard external or in-ground use. Meeting AS 1604 for H3 protection, it is engineered for resistance to rot, fungal decay, and termites, and backed by a 25‑year warranty. While offering durable protection, it retains the workability of untreated pine—allowing easy painting, staining, and fastening—while still meeting AS 1684 mechanical grading requirements.
