Wood description [more info]
Heartwood is light red coloured with an attractive grain. When cut on the quarter the wide medullary rays show an oak like figure. Sapwood is paler.

Wood density [more info]
Green density is about 945 kg/m3 and air-dry density about 560 kg/m3.

Shrinkage [more info]
Tangential and radial shrinkage are estimated as ... per cent respectively.

Workability [more info]
Sharp tools must be used on Banksias as they all have a very open grain and tend to tear when dressing. Sanding, gluing , drilling and turning are rated as good, carving is fair. Banksia will take lacquer, wax and oil well, however, having such and open grain it will require several coats to fill the grain. A wax finish is said to give a silky finish.
