Appearance of White Stringybark Timber
The heartwood of white stringybark is light brown, sometimes with pale pink hues, while the sapwood is lighter and not always sharply differentiated from the heartwood. The timber has a generally uniform grain and medium texture, with occasional interlocking that can produce attractive figuring in some samples.
Applications of White Stringybark Timber
White stringybark is highly versatile, making it suitable for a range of applications. It is widely used in heavy construction, including wharf and bridge construction, railway sleepers, cross-arms, poles, piles, and mining timbers. In general construction, it is used for house framing, cladding, flooring, decking, linings, and joinery. It is also employed in fencing, landscaping, retaining walls, and outdoor furniture. Additionally, the timber is valued for boat, coach, and carriage building, turnery, and structural plywood.
Workability of White Stringybark Timber
White stringybark is a hard timber but machines and turns well. It can be used with standard fittings and fastenings and readily accepts paint, stains, and polish, making it an excellent choice for both structural and decorative applications. Like other high-density species, surface preparation and machining should be done immediately before gluing to ensure optimal results.
Durability of White Stringybark Timber
White stringybark is rated as a class 2 hardwood, with an above-ground life expectancy of up to 40 years and an in-ground life expectancy of 15 to 25 years. While it is not termite-resistant, its sapwood is immune to lyctid borer (powder post beetle) attack and can be readily treated with preservatives to enhance its durability.
Origin and Availability of White Stringybark Timber
White stringybark is a common east-coast species, occurring naturally along the coastal regions and adjacent tablelands of New South Wales and Queensland. It is readily available in its native regions and widely used across various industries in Australia.
Source of White Stringybark Timber
White stringybark is harvested from native forests, ensuring a sustainable supply for construction, furniture, and other applications. Its balance of durability, appearance, and workability makes it a highly sought-after material.
