Natural durability & Treatability

Resistance to decay Class 2-3 – durable to moderately durable
Resistance to dry wood borers Class D – durable (sapwood demarcated, risk limited sapwood)
Resistance to termites Class D – Durable
Treatability Class 4 – non-treatable
Use class covered by natural durability Class 3 – not in ground contact , outside


This species is listed in the NF EN 350 standard. Resistance to decay varies from moderate to good. According to the European standard NF EN 335 of May 2013, performance length might be modified by conditions in which it is used.

Preservation Treatment

Against dry wood borer attacks. This wood does not require any preservation treatment
In case of temporary humidification This wood does not require any preservation treatment
In case of permanent humidification Use of this wood is not recommended.

Sawing and Machining

Blunting effect Fairly high
Tooth for sawing Stellite tipped.
Machining tools Tungsten carbide
Suitability for peeling Not recommended or without interest
Suitability for slicing good
Notes Sawing and machining are difficult due to hardness and interlocked grain


Drying rate Normal to slow
Risk of distortion Slight risk
Risk of case hardening No known specific risk
Risk of checking Slight risk
Risk of collapse No known specific risk
Suggested drying schedule Schedule # 6


Nailing/ Screwing Good but pre – boring necessary.
Notes Very high specific gravity: important that gluing be performed in compliance with the code of practice and instructions for the glue used.
