Sapwood Thickness: 3÷5cm
Sapwood Demarcation: Not clearly demarcated

Resistance to Decay: Class 3 – moderately durable
Resistance to Dry Wood Borers: Class S – susceptible (risk in all the wood)
Resistance to Termites: Class S – susceptible
Treatability: Class 2 – moderately treatable.
Use Class Covered by Natural Durability: Class 2 – inside or under cover (dampness possible)
Durability Notes: Resistance to decay moderate to good according to the species.

Log Buoyancy: Does not float
Log Conservation: Moderate (treatment recommended)
Drying Rate: Rapid to normal
Drying Risk of Distortion: Slight risk
Drying Risk of Case Hardening: No known specific risk
Drying Risk of Checking: Slight risk

Blunting Effect: Normal
Sawing Tooth: Ordinary or alloy steel
Machining Tool: Ordinary
Suitability for Peeling: Bad
