Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Generally straight and plain with a coarse, uneven texture. In this flat-sawn sample, prominent dark/light growth rings are visible with a wide transition between earlywood and latewood.
Color Description
Heartwood ranges from light brown to a reddish-orange hue; sapwood is yellowish-white. The piece shows significant surface silvering and graying on the outer weathered surfaces, indicating oxidation and UV exposure.
Hardness Rating
660 lbf (Soft to Medium-Soft classification)
Durability Rating
Moderately Durable. It is resistant to decay but susceptible to insect attack. It is highly valued for its strength-to-weight ratio in structural applications.
Common Uses
Heavy construction, structural framing, flooring, cabinetry, veneer, and boat building. It is the most common structural timber in North America.
Geographic Origin
Native to Western North America, predominantly the Pacific Northwest and the Rocky Mountains.
Market Value & Sustainability
Estimated Market Value
$3.00 - $6.00 per board foot for select grade; reclaimed or vertical grain clear grades can be higher.
Wood Age Estimate
The piece appears to be reclaimed or salvaged secondary-growth timber, likely 10-30 years old based on the growth ring density and the degree of gray weathering on the exterior faces.
Sustainability Status
Least Concern (IUCN). Widely available and commonly FSC certified; heavily managed through sustainable plantation forestry.
Workability
Works well with machine tools but can be prone to splintering and tearout because of the density difference between earlywood and latewood. Glues and finishes well, though it can exhibit resin bleed.
Notable Features
Distinctive resinous, sweet scent when cut. It possesses excellent stiffness and strength, making it the industry standard for structural softwoods.
Finish Recommendations
Penetrating oils or clear polyurethane. A wood conditioner is recommended before staining to prevent blotchiness caused by varying porosity in the growth rings.
Identification Confidence
High. The characteristic reddish heartwood color, orange-toned latewood bands, and the way the wood has weathered to a charcoal-gray on the exterior are definitive for Douglas Fir.
