Engineered Strength and Stability
Laminated/Finger Jointed (FJ):?/span>Manufactured from kiln-dried (KD) Merbau components, the laminating process creates a "gun barrel straight" product that is highly stable with low dimensional movement, significantly reducing the risk of twisting, cupping, or warping.
- GL17 Structural Rating:?/span>Many 140x42 laminated Merbau products are GL17 rated, meaning they possess exceptional strength and load-bearing capacity suitable for structural beams and handrails.
-
Superior to Solid Timber:?/span>The laminating process removes defects, resulting in a product stronger and more reliable than solid timber of the same size.
Durability and Performance
- Class 1 Durability:?/span>Merbau is highly durable, offering a 40 year life expectancy.
- Natural Resistance:?/span>The timber is naturally resistant to termites, rot, and fungi.
-
Bushfire Approved:?/span>Compliant with BAL29 (Bushfire Attack Level), making it suitable for use in bushfire-prone areas.

Dimensions:?/span>140mm width by 42mm thickness, providing a substantial, heavy-duty feel.
