Sitka Spruce
Picea sitchensis – Family Pinaceae
The main features of this wood are its stability and resistance once it has reached the right balance with environmental humidity.
Its mechanical resistance related to weight is excellent. As it has large-sized logs with regular grain (very small yearly growth-rings) without defects in the mass, the Sitka spruce has been greatly in demand for aeronautical construction and ship masts for many years.
Sitka Spruce origin area
Forests of North-West America.

Douglas
Pseudotsuga taxifolia – Family Pinaceae
This wood is medium resistant from a mechanical point of view, and quite hardwearing.
It is used in civil and architecture construction, structure and furniture for interiors, and in naval construction for masts and small sized structures.
