Appearance
- Colour – Sapwood is greyish-brown and distinct. The heartwood varies from light red to reddish-brown or brown, darkening on exposure.
- Grain – reasonably straight with occasional interlocking.

Characteristics
- Strength – Keruing generally compares with teak in most strength categories, but it is a little stiffer, and about 40 per cent more resistant to shock load.
- Weight – High – about 720 kg/m³. Density can vary by 20% or more.
- Ease Of Drying – dries slowly. Difficult to achieve uniform drying particularly in thick stock. High temperatures aggravates the release of resin so care is needed to reduce this to a minimum and also to reduce the tendency for cupping to occur. There is a high shrinkage during drying and a corresponding high movement potential.
