Species: eucalyptus grandis
Family: Myrtaceae
Clade: Angiospermae
Description: Eucalyptus grandis, commonly known as Flooded Gum or Rose Gum, is a very tall, fast-growing Australian tree. It features smooth, pale grey to white bark that sheds in strips, revealing cream or yellowish patches. Its leaves are glossy, lance-shaped, and green, and it produces clusters of white flowers followed by small, cup-shaped fruits.
Other Local Names: Flooded gum, Kamarere, Rose gum, Grandis, Eucalyptus grandis Grandis

Reference Colour: Red brown
Texture: Coarse
Grain: Straight or interlocked
Interlocked Grain: Slight
Notes: Pale pink to reddish brown wood.

Diameter: 30÷60cm
Density @12% MC: 650kg/m³
Janka Hardness: 750lbf
Crushing Strength @12%MC: 59MPa
Static Bending Strength @12%MC: 103MPa
Longitudinal Modulus of Elasticity E: 15.2GPa
Volumetric Shrinkage Coefficient: 0.48% per %
Total Tangential Shrinkage TS: 10%
Total Radial Shrinkage TS: 5.8%
T/R Anisotropy Ratio: 1.7-
Fibre Saturation Point: 31%
Thermal Conductivity: 0.22W/mk
Sapwood Thickness: 2÷4cm
Sapwood Demarcation: Clearly demarcated

Resistance to Decay: Class 3-4 – moderately to poorly durable
Resistance to Dry Wood Borers: Class D – durable (sapwood demarcated, risk limited to sapwood)
Resistance to Termites: Class S – susceptible
Treatability: Class – 3-4 – poorly or not permeable EUCALYPTUS
Use Class Covered by Natural Durability: Class 2 – inside or under cover (dampness possible)
Durability Notes: Some Eucalyptus grandis sold in the world today comes from young plantations. Wood often has properties inferior to the wood in natural forests. In particular, juvenile wood presents an incomplete duraminisation which explains their lower natural durability compared to the durability of more mature woods.

Log Buoyancy: Does not float
Log Conservation: Low (treatment necessary)
Drying Rate: Normal to slow
Drying Risk of Distortion: High risk
Drying Risk of Case Hardening: Yes
Drying Risk of Checking: High risk

Blunting Effect: High
Sawing Tooth: Stellite-tipped
Machining Tool: Tungsten carbide
Suitability for Peeling: Good
Suitability for Slicing: Not recommended or without interest
Sawing Machining Notes: Like almost all Eucalyptus, E.grandis develops growth stresses which create splits or distortion in the stocks during log sawing. Appropriate sawing techniques must be used: log sawing turning, symmetrical sawing, first sawing by the heart, production of short length stocks.
Assembly Nailing Screwing: Good but pre-boring necessary
Additional Notes: In Brazil, a high percentage of Eucalyptus grandis production is transformed into, charcoal and used by the iron and steel industry
End Uses: Pit props, Built-in furniture or mobile item, Framing, House framing, Panelling, Flooring, Glued Laminated, Poles, Interior joinery
