Tasmanian Oak timber, also known as Tassie Oak, has a good level of durability and has a Janka rating of 5. It is very easy to work with, mostly being used for indoor applications such as flooring and Parquetry.
This is because Tasmanian Oak has an amazing texture and colour, beautifully showing off this stunning soft, light timber. Five Yards by Archier shows the Tasmanian oak colour range. This mix of hardwood species ranges from straw to pale blonde and straw pink. All of the GoodWood Victorian Ash resource is regrowth which limits the variation in colour to a slight mix of colours — primarily in the straw colour range.
Another impressive quality of Victorian Ash timber is that it is very easy to work with machine tools and by hand, resulting in it having a wide range of practical uses. Victorian Ash is usually the perfect material when building balustrades and staircases because it has minimal shrinkage after it has dried. Its flexible nature of the timber also results in it being highly used in F17 seasoned structural framing, which is one of the highest grades commercial framing timber can receive.
Victorian Ash timber has a Janka rating in the 4. When used in above ground applications, Victorian Ash timber features an impressive life span between 7 to 15 years.
You can learn more information by reading our Victorian Ash timber brochure. Five Yards by Archier shows the variation in Victorian ash colour. Although they share many similarities, including species makeup, there are some minor differences between Victorian Ash and Tasmanian Oak.
Regarding the basis of colour, figure and grain when differentiating veneer, the subtle differences between Tasmanian Oak and Victorian Ash become more visible. The other main difference is their price. Victorian Ash tends to be more expensive due to Eucalyptus Regnans and Eucalyptus Delegatensis producing a much smaller portion of light-coloured veneer. Tasmanian Oak, on the other hand, is less expensive due to being widely available.
Both species are suitable for many of the same applications and are quite easily used in unison. The main uses for Tasmanian Oak and Victorian Ash hardwood timber include:.
The quality of species can depend on the timber mill, grading and their processes. Unit shrinkage: E. These values apply to timber reconditioned after seasoning. Durability above-ground: Class 3 life expectancy 7—15 years.
Durability in-ground: Class 4 life expectancy 0—5 years. Lyctine susceptibility: untreated sapwood of E. Termite resistance: not resistant. Preservation: sapwood readily impregnates with preservative, but penetration of heartwood is negligible using available commercial processes.
Seasoning: be careful when seasoning as prone to collapse and internal checking; also prone to surface checking on the tangential surfaces. Hardness: firm to moderately hard rated 3 and 4 on a 6-class scale to indent and work with hand tools.
Machining: machines, and turns well, to a smooth surface. Fixing: no difficulty using standard fittings and fastenings. Gluing: bonds satisfactorily using standard procedures. Finishing: readily accepts stain, polish and paint. Identification features General characteristics Sapwood: similar to the heartwood. Heartwood: pale brown to white-brown and often with pinkish tints. Texture: open to moderately open; grain is usually straight; gum veins sometimes prominent in E.
The heartwood ranges from pale pink to yellowish brown and a walnut colour can be achieved by steaming with ammonia. The heartwood is often indistinguishable in colour from the softwood. Care needs to be taken when drying Victorian ash because it is prone to collapse and internal checking, as well as surface checking on the tangential surface.
There is minimal shrinkage after drying. To ensure good quality boards, logs are quarter-cut, which provides excellent dimensional stability. Reconditioning is standard practice. Victorian ash can be used for general construction, such as F17 seasoned structural framing, but its moderate above-ground durability and its consistent and even colour means it is best suited for interior applications such as flooring, panelling, mouldings, staircases, handrails, balusters, cupboards, bench tops high value joinery, furniture as well as protected e.
Victorian ash is also used to manufacture plywood and may also be used for boxes, crates and paper pulp. Victorian ash can be grown as a plantation timber due to its quick growth and resistance to insect attack.
Modulus of Elasticity - Unseasoned:. Maximum Crushing Strength - Seasoned:. Not Resistant. Victorian ash timber can range from a pale pink to pale yellow or brownish colour. The heartwood and sapwood colours are generally quite hard to tell apart, with sapwood 25 to 50mm wide. Victorian ash features a moderately course texture and has a predominately straight grain, although it may be wavy in parts resulting in a fiddleback appearance.
Gum veins are also a common appearance feature. It will provide a light, creamy-coloured timber for appearance applications, although a richer walnut colour can also be achieved by steaming Victorian ash with ammonia. Victorian ash can be used for protected structural applications, such as high strength seasoned structural F17 timber framing, but it is best suited to indoor appearance applications and furniture due its low to moderate durability, its excellent working properties and its consistency in colour.
