Mechanical properties: All three species have medium bending strength and stiffness and high crushing strength. Can be steam bent but some fibre disruption can occur. Kiln dry densities vary from 550kgs/m³ (34lb/ft³) and 750kgs/m³ (47lb/ft³).

Working properties: It is generally easy to work with hand and machine tools with slight blunting of edges. Pre drilling for nails and screws to avoid splitting. Glues satisfactorily, takes most stains and finishes well.
