Appearance of Red Stringybark Timber
The heartwood of red stringybark is pale red or pinkish-brown, contrasting with its creamy sapwood, which is typically about 50 millimetres wide. The timber is close-textured, and its interlocked grain frequently produces a striking fiddleback figure, adding to its decorative appeal.
Applications of Red Stringybark Timber
Red stringybark is versatile and suited for a range of uses. In light construction, it is commonly employed for fencing, framing, weatherboards, posts, and poles. Its strength and moderate durability also make it suitable for engineering applications, such as sleepers, utility pole cross-arms, and components in bridge and wharf construction. In addition, its aesthetic qualities have led to its use in cabinetmaking for furniture and benchtops.
Workability of Red Stringybark Timber
Red stringybark is a highly workable timber that machines, routs, saws, and sands efficiently. Occasionally, the timber may exhibit natural features or surface cracking. Its density requires the use of polyurethane glues for effective bonding, and it performs well with standard fastenings and fittings. Red stringybark readily accepts most standard coatings and responds particularly well to oil-based finishes, making it ideal for cabinetmaking and other decorative applications.
Durability of Red Stringybark Timber
Classified as moderately durable, red stringybark offers reliable performance in a variety of settings. It is suitable for outdoor applications when treated and can withstand exposure in structural and engineering contexts.
Origin and Availability of Red Stringybark Timber
Red stringybark is native to southeast Australia, with timber sourced primarily from New South Wales and Victoria. Supplies are generally limited, making it a less common choice, though still accessible through specialist timber suppliers.
Source of Red Stringybark Timber
Red stringybark is harvested from native forests, offering a sustainable option for both structural and decorative uses. Its moderate durability, versatility, and attractive appearance make it a sought-after material for a variety of projects.
