In the woodworking industry
The log has a diameter of 60 to 120 centimeters, the thickness of sapwood is 3-7 centimeters (clearly expressed), the texture is fine. The wood color is brown, yellow-brown or gray-brown with black stripes or veins with a golden sheen, with black deposits in the pores.
Physical characteristics: Density: 0.53 g / cm3 Monnin hardness: 2.3 Volume shrinkage coefficient: 0.43% Total radial shrinkage: 3.7% Fiber saturation point: 27% Durability: resistant.
Mechanical characteristics: Crush resistance: 47 MPa. Static bending strength: 72 MPa. Elastic modulus: ~ 10000 MPa.
Resistance to fungi: class 3-4 - from moderate to low resistance; borers: persistent, risk limited to sapwood; termites: class S - susceptible; permeability: 3-4 - weak or impenetrable; class of use: 2 - indoors or under cover (dimming is possible).
Requirement for protective treatment: Against wood borers - does not require protective treatment; against the risk of temporary wetting - requires the necessary protective treatment; against the risk of constant moisture - not recommended for use.
