Resistance to termites Class D – Durable
Treatability Class 3 – poorly treatable
Use class covered by natural durability Class 3 – not in ground contact, outside


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 Sometimes difficulties with sawing and machining due to interlocked grain. Good finish with filling


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
Notes must be dried slowly to prevent defects. A period of air drying prior to kiln drying is recommended
Suggested drying schedule Schedule # 7


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

Commercial Grading

Sawn timber appearance grading

According to NHLA grading rules (2015) Possible grading: FAS, Select, Common 1, Common 2, Common 3. In French Guiana, the local name of this species is "COEUR DEHORS". Grading is done according to local rules "Bois guyanais classés". Possible grading: Choice 1, choice2, choice 3, choice 4

Fire Safety

Conventional French grading Thickness > 14 mm: M3 (moderately inflammable)
Thickness < 14 mm: M4 (easily inflammable)
Euroclass grading D-s2, d0
Default grading for solid wood that meets requirements of European standard NF EN 14081-1 (April 2016): structural graded timber in vertical uses and ceilings with minimal mean density of 0.35 and minimal thickness of 22 mm.
