Karri
Species profile
Karri presently commercialized does not come from primary forests anymore ; it only comes from regrowth forests (Australia) as well as plantations (in particular South Africa).

The wood is pinkish brown. It has clearly demarcated sapwood. The grain is straight or interlocked and the texture is medium. Density at 12 % moisture content: 0.90 g/cm3.

The blunting effect is fairly high and peeling and slicing is not recommended or without interest. Nailing is good but pre-boring is necessary. Gluing is correct. It dries slowly.

Karri is durable to fungi and is durable to dry wood borers; sapwood demarcated (risk limited to sapwood).

Karri can be used for several applications such as:
• interior: e.g. high class furniture, flooring, stairs, panelling, industrial or heavy flooring, moulding
• exterior: e.g. panelling, bridges, vehicle or container flooring, heavy carpentry
