NATURAL DURABILITY AND TREATABILITY
| Funghi (according to E.N. standards): |
class 2 - durable |
| Dry wood borers: |
durable - sapwood demarcated (risk limited to sapwood) |
| Termites (according to E.N. standards): |
class M - moderately durable |
| Treatability (according to E.N. standards): |
class 4 - not permeable |
| Use class ensured by natural durability: |
class 3 - not in ground contact, outside |
| Species covering the use class 5: |
No |
| Note: |
This species is listed in the European standard NF EN 350-2. Durability is linked to the presence of water soluble tanins. It decreases with tanins washing in case of harsh exposition. |
SAWING, MACHINING AND ASSEMBLING
| Blunting effect: |
normal |
| Sawteeth recommended: |
stellite-tipped |
| Cutting tools: |
tungsten carbide |
| Peeling: |
good |
| Slicing: |
nood |
| Note: | Steaming is recommended before slicing. |
| Nailing / screwing: |
good but pre-boring necessary |
| Gluing: |
correct |
| Note: |
Gluing must be done with care: wood is dense, slightly acid and rich in tanins. Nail or screw corrosion if in contact with humidity. |
