140x65 Merbau Laminated GL17S Structural Beam
Deliver lasting strength for outdoor structures with this 140x65 Merbau Laminated GL17S structural beam. Built for harsh Australian conditions, it remains straight and sturdy across pergolas, verandahs, and decking projects thanks to finger-jointed lamination.
The durable kiln-dried hardwood offers a reliable option for service class 3 applications, while the GL17S structural rating supports demanding, exposed installations. A smooth Dar finish provides a high-quality surface ideal for visible timber work, with a rich yellow-brown to reddish-brown appearance and a natural grain pattern that ages gracefully.
Note: Merbau is tannin-rich and may leach during the initial months. Proper management and timely coating with oil or paint helps protect surrounding surfaces and the timber itself.
