Collection: Victorian Ash Timber

Victorian Ash (E. delegatensis & E. regnans) is the trade name for two of Australia’s tallest hardwood species—Mountain Ash and Alpine Ash. This timber grows in the alpine regions of Victoria, where its quality and versatility have made it a popular choice for a range of interior and protected structural applications. Victorian Ash should not be confused with Tasmanian Oak, which includes Mountain Ash, Alpine Ash, and Messmate and has a more varied color palette. Notably, Victorian Ash is resistant to lyctid borer, making it a durable option for interior applications.

Appearance of Victorian Ash Timber

Victorian Ash displays a beautiful spectrum of pale pink to yellowish-brown hues, with the color of the heartwood often difficult to distinguish from the sapwood. The wood typically has a straight grain, though it can also exhibit a unique fiddleback pattern and visible gum veins. The texture is moderately coarse, adding depth to its visual appeal. For a richer look, Victorian Ash can be steamed with ammonia, giving it a warm, walnut-like color.

Common Applications of Victorian Ash Timber

While Victorian Ash offers moderate durability, it excels in interior applications due to its stability and uniform color. It is commonly used for high-quality furniture, flooring, paneling, mouldings, staircases, handrails, balusters, cupboards, bench tops, and intricate joinery work. Victorian Ash is also suitable for protected structural uses, such as F17 seasoned structural framing, and can be found in agricultural tools, boxes, crates, plywood, and paper pulp production. Its quick growth and resistance to insect attack make it an ideal plantation timber as well.

Workability of Victorian Ash Timber

This timber is known for its excellent workability, making it easy to plane, sand, finish, and glue. Victorian Ash also bends and steams effectively, allowing it to be shaped for detailed joinery and interior applications. To maintain quality, logs are quarter-cut for stability, and reconditioning is standard practice, ensuring minimal shrinkage and optimal performance for refined projects.

Origin and Availability of Victorian Ash Timber

Kosny Timber sources Victorian Ash from native forests primarily in Victoria, with availability extending to other parts of Australia, including Tasmania and New South Wales. Known for its high quality, Victorian Ash is widely sought for its beauty and adaptability in both residential and commercial applications.
