Sapwood Demarcation: Not demarcated

Resistance to Decay: Class 5 – non-durable
Resistance to Dry Wood Borers: Class S – susceptible (risk in all the wood)
Resistance to Termites: Class S – susceptible
Treatability: Class 1 – treatable
Use Class Covered by Natural Durability: Class 2 – inside or under cover (dampness possible)
Durability Notes: Red heartwood is not permeable to preservation products.

Log Buoyancy: Not applicable
Log Conservation: Low (treatment necessary)
Drying Rate: Slow
Drying Risk of Distortion: High risk
Drying Risk of Case Hardening: Yes
Drying Risk of Checking: High risk

Blunting Effect: Normal
Sawing Tooth: Stellite-tipped
Machining Tool: Tungsten carbide
Suitability for Peeling: Good
Suitability for Slicing: Good
Sawing Machining Notes: The frequent presence of growth stresses in the logs might complicate sawing (risk of splits and distortions in boards during sawing). Beech wood has a good aptitude for bending.
Assembly Nailing Screwing: Good but pre-boring necessary
Assembly Notes: Very absorbent wood: to be taken into account when gluing.
Additional Notes: Beech wood is easy to stain
End Uses: Arched goods, Built-in furniture or mobile item, Turned goods, Moulding, Coffins, Flooring, Boxes and crates, Seats, Veneer for back or face of plywood, Marquetry, Interior joinery
