Jarrah (Eucalyptus marginata) is a hardwood timber, native to Western Australia. Its heartwood is a rich, brownish-red, with occasional dark brown flecks on the end grain and boat-shaped flecks on flat sawn surfaces. It may also have black streaks and bark inclusions. Upon exposure, the wood changes to a rich mahogany-red. The grain is often interlocked or wavy, with a moderately coarse, even texture. Gum pockets and veins may be present. The clearly defined sapwood is commonly pale yellow but can darken over time.
Jarrah is a highly versatile timber, with many uses. It is commonly used for furniture, tool handles, flooring and more. Its strength, durability and excellent working properties make it an ideal choice for a variety of applications.
Jarrah is a stunning timber, with its beautiful red hue and contrasting sapwood. Its unique grain and texture are sure to add character and distinction to any project.

Jarrah wood is a very durable timber.
The drying and seasoning of Jarrah 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; Jarrah - needs careful drying, with partial air-drying before kilning. Broad timber sections may warp and check in drying and collapse can occur. Movement in service is medium. 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. You will find more information about the suitability of this wood, for any proposed application, by using our interactive system and the filters shown.
Jarrah is a dense, heavy, hard wood that has medium bending and high crushing strength. Jarrah is satisfactory for steam bending. Jarrah is fairly challenging to work with hand tools and when machined it has a tolerable blunting effect on tools. Jarrah glues, turns and polishes very well.

Commonly asked questions about Jarrah Wood
Is Jarrah a hardwood or a softwood? Jarrah is a hardwood. It is the same for; is Jarrah hardwood or softwood? - Jarrah 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 Jarrah 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 Jarrah? Jarrah can be described as brown, dark red, red
Is Jarrah good for outdoor use? or is Jarrah good for exterior use? Jarrah is most suited for exterior/external use. Jarrah can 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
