Sheoak Hardwood


Sheoak, also known as Allocasuarina freseriana, is a timber species native to Australia. Its heartwood ranges in colour from orangey-red-brown through to burgundy and dark red, and is distinguished by its lighter sapwood. It has a moderately fine, straight grain with an even texture and large, prominent rays, which is what likely led to it being referred to as 'oak' by European settlers. Its name 'she' oak may be derived from its relative softness when compared to true oak.

Sheoak is a highly versatile timber and can be used for a variety of applications, including panelling, furniture, turnery and more. It is a sustainable and legal source of wood, making it an excellent choice for a variety of projects.

Durability Notes:
Sheoak sapwood can be susceptible to attack from lyctus borers, but the heartwood is durable. Overall a moderately durable timber.

The drying and seasoning of Sheoak is dependant on a number of factors; the speed in which it is processed after felling and logging, the method of drying and the specific kilns or location (if air dried). Generally the care taken by those processing the wood will have an impact on its drying and seasoning. As an overview; Sheoak - can be challenging to dry, as it has a tendency to warp and check with high shrinkage. However, when dry it displays only a small amount of movement and is stable in service. Please note that all wood is liable to move when in service plus there can be dimensional change. The extent of this will depend on; the stability of the species itself, the conditions it is exposed to, the coating, decoration and protection.

Sheoak is hard and of medium weight and strength. Sheoak machines and cutes reasonably well and a smooth surface can be achieved. There is only a slight blunting effect on cutting tools. Sheoak holds screws well but can split when nailed, so pre-drilling or extra care is recommended. Sheoak glues and steam-bends well and can be brought to a high polish.

Typical Uses:
Furniture, Flooring, Cabinetry, Decorative Panels, Joinery, Exterior Cladding, Decking, Firewood.

Commonly asked questions about Sheoak Wood

Is Sheoak a hardwood or a softwood? Sheoak is a hardwood. It is the same for; is Sheoak hardwood or softwood? - Sheoak is a hardwood.

Most groups/families of species share the same characteristics but this normally relates to their life as plants. Individual species do not always share the same characteristics as their relatives, in terms of the wood. Many factors influence how we use the wood and what we use it for, including where it grows, how it is forested, how it seasons/dries, etc. The answers to the following common questions, therefore relate to this particular species/wood and not the Sheoak family as a whole. Even more specific – our answers relate to the wood (as we know it) in its form as a useable resource.

What colour is Sheoak? Sheoak can be described as brown, dark red, red, orange

Is Sheoak good for outdoor use? or is Sheoak good for exterior use? Sheoak is most suited for internal/interior use. Sheoak should not be used as an exterior/external timber (without treatment).

Whether the wood is naturally durable or not we would still recommend that it is decorated and/or coated with a suitable product to provide protection and/or maintain its appearance. This even applies when using the wood internally as, even subtle, changes in temperature or humidity will affect the wood. This will depend on the application/purpose of the wood and the user’s desired appearance. We also recommend that a recoating, care and maintenance programme is adhered to, for the life of an exterior wood. Wood cannot rot if it is kept dry – coatings and decoration can provide this protection. All of that said there are many durable timbers that are often left to weather naturally and will last for many years untreated/coated – movement and visual changes will occur but this is sometimes the desired effect. All wood is hygroscopic (it 'wants' to be in tune with its environment) it will therefore take on water from moisture in the air (or when directly exposed to or submerged in water) and ‘release it’ when dry or exposed to heat. This, inevitably, results in movement and dimensional change. For more about moisture in wood please click here - Moisture in wood
