Strength & Precision Grading
Structural potential in recovered timber is unlocked through rigorous stress grading. Unlike plantation timber, mature urban hardwoods like Jarrah and Marri offer exceptional density and mechanical stability. Every piece designated for structural use—from beams to posts—must undergo visual or mechanical stress grading to Australian standards (AS 2082). This ensures that load-bearing capacities are verified for engineering specifications, providing peace of mind for residential and commercial frameworks.
Structural Applications
- Residential: Decorative load-bearing beams, exposed rafters, and lintels.
- Landscaping: Retaining wall sleepers, structural bollards, and heavy-duty bridging.
- Light Commercial: Interior fit-out framing, mezzanine supports, and shopfront structural posts.
Managing moisture and identifying defects is the hallmark of structural timber recovery. Success depends on proper seasoning—transforming 'green' timber into stable, kiln-dried structural components. We carefully analyse natural characteristics such as gum veins and knots, distinguishing between aesthetic features and structural defects that affect fibre integrity.
Practical Limitations
Structural hardwood recovery is localised and resource-dependent. Unlike industrial plantation products, urban recovered timber is restricted by the diameter and length of individual salvaged logs. Sizing is often custom rather than standardised. Furthermore, any structural application must be accompanied by an engineer's sign-off based on the specific grade assigned to the batch, ensuring absolute compliance with current Western Australian building codes.
