Australian Oak/Ash


Australian Oak is a mixture of two Eucalypt species. It ranges in colour from pale pink to brown straw. It is straight, open and even grained with a uniform texture, usually all quarter-sawn for stability with excellent staining properties. It is light in colour, varying from straw to reddish brown with intermediate shades of cream to pink. It is recognised for its excellent staining qualities.  

It is a versatile timber perfect for both construction and interior applications, used extensively for flooring, panelling, interior joinery, architraves and skirting boards.

Workability: A strong and stable timber, Australian Oak/Ash offers good all round workability. It planes, sands, finishes and glues well, and will readily bend making it deal for many applications including furniture.

Working Qualities: A strong and stable timber, Tasmanian oak offers good all round workability. It planes, sands, finishes and glues well, and will readily steam and bend. This makes Tasmanian oak is ideal for internal applications and furniture.
Uses: Tasmanian oak can be used for protected structural applications, such as timber framing, but it is best suited to indoor applications and furniture due its low to moderate durability. Flooring, paneling and high-end joinery are some of its more common applications, although it is also used for agricultural implements, oars, cooperage, boxes, crates, paper pulp and in the manufacture of plywood.
