Blackbutt

Blackbutt is a coarse-textured, strain-grained timber typical of the harsh Australian coastal climate in which it thrives. It's hard and tough but relatively easily worked – qualities that have made it a popular choice for decking. Blackbutt is honey blonde coloured, and its sapwood is resistant to borers.


Heartwood is pale brown, but northern material may sometimes display a pinkish tinge. Sapwood is distinctively paler. Texture medium and even. Grain is usually straight. Gum veins are common.

Jarrah

Jarrah is renowned for its rich red colours that deepen over time. The heartwood ranges from deep browns to burgundy hues. Jarrah sapwood exhibits shades from pale yellow to pink-orange. The timber displays a moderately coarse and even textured grain. The occasional incidence of wavy and interlocking grain produces some samples with a sought-after fiddle-back figure.

Silvertop Ash

Silvertop ash has a narrow sapwood, which is not clearly distinguishable from its heartwood. The heartwood is brown and sometimes pinkish in colour and often features the grain interlocked with growth rings. With a medium texture, silvertop ash is also recognisable by the common occurrence of gum veins, the markings of pinhole borers and pencil streaks.

Spotted Gum

Spotted gum is a tough timber that has been weathered by harsh conditions. This weathering produces spotted gum's unique characteristics: gum veins and a wavy grain, which results in a 'fiddleback' effect. Architects and Specifiers favour spotted gum for its individuality and stunning colour palette, which ranges from light browns to dark reds. It is also known as lemon-scented gum.

Wormy Chestnut

No two pieces of Australian wormy chestnut are ever the same.

Deep in the forests of Southern Eastern Australia, the trees are affected by bushfires, years of drought, attacks by insects, and the occasional flood and winds so strong that the trees stunt their growth to cope with the environment. It is from these trees that the Australian wormy chestnut is born, with each piece showing nature's signature. Deep red gum veins formed by fire, ambrosia beetle marks, pin holes and squiggly worm marks are all reflected in Australian wormy chestnut.

Botanical Name:

A blend of species, predominantly Eucalyptus oblique, Eucalyptus sieberi & Eucalyptus fastigata

Origin of Timber:

South-East Australia
