Premium 70x45 Solid Merbau Timber: Structural Excellence & Premium Screening
Decking Wood QLD is the premier Merbau specialist in Queensland, supplying premium, sustainably sourced 70x45mm solid Merbau timber for structural applications, high-end screening, and architectural features.
Known botanically as Intsia bijuga and commonly referred to as Kwila, Merbau is a highly durable Class 1 hardwood. The 70x45mm profile delivers structural-grade integrity with an F27 stress rating, making it a versatile timber that combines exceptional load-bearing strength with a beautiful, clean finish.
Key Product Specifications
- Dimensions: 70mm width x 45mm thickness.
- Available Lengths: Set lengths ranging from 2.4m up to 6.0m to suit precise project needs.
- Weight: Approximately 2.7 kg per linear meter (kiln-dried).
- Stress Grade: F27 Structural Grade, providing high bending strength and stiffness.
- Durability Class: Class 1 Above Ground / Class 2 In-Ground (highly resistant to decay, rot, and insects).
- Hardness Rating: Janka rating of 8.6 kN (excellent resistance to impact, scratching, and wear).
- Fire Rating: BAL 29 certified (Bushfire Attack Level), naturally compliant for fire-prone areas without extra treatment.
- Grade: Solid Select Grade with pencil-round edges, ensuring minimal imperfections and smooth installation.
Primary Applications
The F27 70x45mm profile is ideal for both secondary structural framing and visible architectural elements:
- Handrails & Balustrades: Widely utilised for premium external deck handrails, top rails, and balusters.
- Heavy-Duty Screening & Battens: Perfect for building bold, modern horizontal privacy screens and gates, as well as vertical architectural battens.
- Decking Sub-Frames: Used as joists or light bearers in low-profile sub-frames where depth is limited but strength is required.
- Pergola Slats & Rafters: Adds structural stability and clean linear aesthetics to the roof framework of gazebos and pergolas.
- Stair Balustrades & Carpentry: Excellent for framing external stairs and internal architectural joinery.
Why Choose Merbau Hardwood?
- Superior F27 Strength: Offers much higher load capacities and greater span capabilities than standard treated pine.
- Kiln-Dried (KD) Stability: Carefully seasoned to a controlled moisture level to minimise shrinking, twisting, warping, or cupping.
- Natural Longevity: Rich in natural oils that shield the timber from termites and fungal attacks, lasting 25+ years above ground.
- Distinctive Look: Features deep golden-to-reddish-brown tones intertwined with signature mineral flecks that deepen beautifully over time.
Installation & Maintenance Tips
- Pre-drilling & Fastening: Always pre-drill and use Grade 304 or 316 stainless steel fixings to eliminate the risk of corrosion and black staining.
- Tannin Management: Merbau naturally bleeds rich red-brown tannins when exposed to moisture. Use a tannin remover or coat the timber before installation if it sits near light concrete or tiles.
- Oiling & Sealing: Apply a premium oil-based timber sealer directly after installation to preserve its deep natural hues and shield it from UV weathering.
