Solid Strip Timber Flooring
Blackbutt is a blonde Australian native, widely used in modern and traditional architecture. The Eucalyptus pilularis tree is grown in the coastal regions of New South Wales and Queensland. The name Blackbutt correlates with the tree’s appearance after the effect of bushfires. The buttress of the tree is often charred black due to previous bushfires.
Blackbutt is not fashionable, it is a classical hardwood flooring species and has been used for decades and is frequently specified at Provincial Floors. Blackbutt ranges from golden yellow to pale browns. Occasionally minute pinkish tones can be present. Blackbutt has a beautiful even texture and can add a classy and timeless look and feel to your home. Further characterised by relatively straight-uniform grain, providing appeal for interior uses.
Blackbutt is a strong and durable hardwood and provides incredible fire resistance. In fact, the building commission in Victoria classified Blackbutt as one of the seven hardwood species that is suitable for constructions in bushfire regions – although overall thickness must be above 18mm.
- Janka Rating
Janka Rating: 9.1
Hardness rating: The hardness rating of a timber species is measured by the Janka Test. This is a standard test which measures the penetration into the timber of a common load and projectile. The results relate to a hardness capacity of the material and are expressed in kN. This information is useful where the timber may be subject to potential damage from impacts e.g. a dance floor. There are 2 sets of published figures; one for 'Green' or freshly felled timber and one for seasoned timber - i.e. timber with a moisture content of 12%.
The ratings given here are:
Soft - less than 5.5
Moderate - 5.5 to 7.0
Hard - 7.1 to 10.0
Very Hard - greater than 10.0
Flooring is graded during manufacturing to Australian Standards resulting in Select, Standard, Feature and Prestige and Rustic grade. Grading is simply a sorting process based on a set of rules that permits specific features up to a certain size and number. This species may or may not carry all of these grades, contact our office for accurate gradings.
Select Grade is a subtle feature grade of timber flooring which provides a limited variation in natural characteristics. The features that are present are relatively small and few in number. Irrespective of the species although visible do not dominate the appearance of the floor. It has been carefully graded, floorboard by floorboard to ensure that it meets strict quality standards. It has a sleek uniform look that is well suited to modern, minimalist and traditional styles. This will have the least number of natural features such as pin holes and gum veins.
This grade contains boards that may be moderately featured. Where gum veins are more prevalent in a species, considerably more character is provided to the floor and may look quite dominant in light coloured species. Species in this grade with less gum vein may appear more lightly featured due to smaller features being prevalent such as those from previous borer activity. Standard Grade is distinguished by highlighting selective gum veins, spirals, burls, insect trails and other natural variations that give timber floors a unique character as individual as a signature. This grade is a visual chronicle of forest history including bush fires, floods, drought, insect travels and the natural variations that appear in the grain of Australian native hardwoods. Standard grade is carefully graded to include the most interesting variations and distinctive timber marking to enhance the looks of a timber with a moderate amount of natural features.
Feature Grade features a high level of natural characteristics. In many respects this grade can look similar to Standard Grade but with the features a little more frequent and dominant. This grade offers a unique rustic aged appearance with extenuated natural features including gum vein, knots, face checking and insect travels.
Combines the features of Select Grade and Standard grade to provide a floor with more character than a Select Grade Floor.
Fully featured to provide an old world charm. It may contain features that are more prominent than Feature Grade but with the structural integrity of a Feature Grade Floor.
