DescriptionTallowwood is a large hardwood
found along the coast and coastal ranges between the Hunter River in
New South Wales up to the Maryborough district of
Rough bark persists to the small branches and is
brown to red-brown, soft and fibrous.
The heartwood is a
greyish-yellow colour with tinges of olive green and is a hard,
fairly close-grained timber. The sapwood is distinctly paler. The
timber is free of gum vein, something quite rare in eucalypts.
timber has a slightly ‘greasy’ feel which comes from the high levels
of triterpenes among its extracts. This feature can also impact on
adhesive bond strength to the material. The problem can be resolved
to a certain extent by washing the area(s) to be glued with a 10%
solution of sodium hydroxide.
The heartwood is
very durable (Class 1). The material works well and has been widely
used in a variety of applications including decking, flooring,
domestic structures, heavy commercial construction, sleepers, marine
structures, poles, piles and bridges. Definition
