STRUCTURAL LUMBER
Douglas Fir
The backbone of Pacific Northwest construction - exceptional strength, stability, and versatility for all your building needs.
Douglas Fir is the premier structural lumber species of the Pacific Northwest, prized for its exceptional strength properties and versatility. This remarkable softwood combines high strength with dimensional stability, making it the foundation of modern wood-frame construction.
With one of the highest strength-to-weight ratios among softwoods, Douglas Fir provides exceptional structural performance. Its high modulus of elasticity and bending strength make it ideal for spans and load-bearing applications.
