Blackbutt Flooring Sydney
Blackbutt is a tall hardwood, growing in large numbers in coastal forests between Bega in New South Wales and Maryborough in Queensland. A moderate to large tree with a long, straight cylindrical trunk, Blackbutt reaches heights of 40 to 60 metres, with a diameter of up to three metres.
Blackbutt literally means “half bark.” It has rough fibrous bark on the lower trunk and a smoother whitish to yellow upper trunk and branches where bark has shed in strips. The heartwood of Blackbutt is pale brown with a faint tinge of pink when freshly cut, while the sapwood is usually slightly paler in colour. The grain tends to be straight with some gum veins present but little evidence of growth rings.
Blackbutt is classed as Class 1 with a life expectancy over 40 years when used above ground and is Class 2 with a life expectancy 15 to 25 years when used in-ground. Blackbutt is considered naturally resistant to termites and its sapwood is not susceptible to lyctid borer attack.
Blackbutt is ideal for flooring but is also used in a variety of aesthetic and structural building applications including weatherboards, railway sleepers and bridge planks. It may also be used for posts and poles if it is treated with a suitable preservative. Other uses include boat building, coach and carriage building, structural plywood and hardboard. Blackbutt’s botanical name is eucalyptus pilularis and it has a Janka rating of 9.1.
