Merbau Dar Solid 90×42

Merbau 90 × 42 mm DAR: kiln-dried, Select Grade hardwood, dressed all round and used for external handrails, rails and pergola framing. Class 1 durable above ground, termite resistant and accepted for bushfire areas up to BAL-29.

• Lengths: 1.8 m to 5.7 m, sold per length
• Timber: Merbau (Intsia bijuga and I. palembanica) from Southeast Asia and the Pacific; orange-brown, darkening with age; about 830–860 kg/m³, Janka hardness 8.5 kN
• Durability: Class 1 above ground, which the Queensland Government rates at more than 40 years’ expected life; the heartwood is termite resistant
• Bushfire: Merbau is on the AS 3959 list of bushfire-resisting timbers, accepted up to BAL-29
• Not for in-ground use: Merbau is only Class 3 in-ground, so keep posts off the soil with galvanised stirrups rather than setting them in concrete
• Stability: kiln-dried, and low-movement for a hardwood, so it holds its line in screens and battens
• Fixing: pre-drill — WoodSolutions notes Merbau tends to split unless pre-bored — and keep fixings at least 12 mm from edges and ends. Use stainless steel within 1 km of the coast or 1 m of a pool
• Tannin: new Merbau bleeds tannin that stains concrete, paving and render. Seal every face and cut end, and to finish it straight away, draw the tannin out first with Intergrain UltraPrep Tannin & Oil Remover
• Finishing: coat every face and cut end before fixing, then recoat at least once a year, or leave it bare to weather silver-grey. Oils we stock: CUTEK CD50, Intergrain Universal Timber Oil or Sceney’s Timber Decking Oil
• Not structurally graded: these are dressed appearance-grade boards. For a structural span use GL17 finger-jointed Merbau or LVL
• At Greenhill: stocked at 170 Settlement Road, Thomastown, with pickup or delivery across Melbourne and regional Victoria. See all our dressed Merbau.
