Jarrah is a hardwood used for both indoor and outdoor applications. For outdoor use jarrah is very often chosen for decking timber by Australian home owners and also Australian businesses such as restaurants and hotels.
The native Australian Jarrah is an environmentally responsible timber to use for two main reasons. It is sustainably harvested in the Western Australian plantations.
Characteristics and Benefits of Jarrah Decking
Jarrah has a hardness rating of 8.5. To get an idea of the relativity of hardness, pine (soft timber) has a rating of 3.3 whilst the hardest of all timbers grey ironbark has a rating of 14.0.
Jarrah timber decking has a good oil level composition. This means that jarrah timber is suitable for sanding and varnishing and providing a great transparent finish.
Colour and Grain
The colour of the native Australian jarrah is a lovely red with shades of brown. Jarrah timber decking has an attractive (even beautiful) grain pattern. Together the lovely colour and grain makes jarrah one of the most popular Australian timbers.
Overtime, the redness of the jarrah timber decking deepens and transpired to a burgundy colour. If left untreated (stain or oil) and aged naturally, the timber will turn grey.
Jarrah has a class 2 durability rating which means the timber has relatively long expected lifetime usage depending on how its cared and maintained.
It is a natural termite resistance.
Jarrah decking timbers are naturally rot and decay resistant. This makes jarrah decking an excellent choice for pool decking and fwooden spas and hot tubs.
Due to high density of the wood, making Jarrah highly fire retardant
*Blackbutt timber Decking*
Blackbutt decking is a good choice for an outdoor timber deck. The durability and strength of the timber means that your deck will stand the test of time. The attractive colour and pattern of the wood also means a highly attractive deck. The timbers acceptance of stains and varnish too make it a good choice as a deck building material. Blackbutt decking boards if left untreated are also attractive providing a natural, weathered appearance.
Blackbutt timber is fire resistant. One of the top choice for bushfire region.
Blackbutt timber is strong and durable.
Blackbutt decking timbers have very little movement.
Blackbutt wood can also be prone to surface checking if it is not stained or oiled properly.
*Spotted Gum Timber*
Strong and durable, Spotted Gum is a popular Australian hardwood often used in exterior projects such as decking. It’s also commonly used in a variety of structural and internal applications.
Also known as Lemon-scented Gum, Spotted Irongum, Eucalyptus maculata, Corymbia citriodora, Eucalyptus citriodora, Corymbia henryi, and Eucalyptus henryi, Spotted Gum is actually the common name for four species of timber that grow along the east coast of Australia, from the New South Wales/Victoria border to Maryborough in Queensland. It is a very common form of Eucalypt, and one you have likely seen a lot of if you live in Australia.
As decking boards, Spotted gum weighs approximately 1010kg per cubic metre, which gives a good indication of its excellent density. Unseasoned Spotted Gum can expect 0.3%shrinkage when laid, which is a great indicator of its suitability for decking uses as movement and shrinkage are unlikely. In addition, it is naturally termite resistant, as well as very low in tannin compared to other hardwood such as Merbau
