Sitka Spruce and Douglas

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.
