Douglas Fir
Scientific name: Pseudotsuga menziesii
Overview
Douglas Fir is one of the most important structural softwoods in North America and is widely used in construction, framing, beams, and engineered wood products. Despite its common name, it is not a true fir and is valued for its strength, stability, and availability.
