Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Straight but coarse, showing prominent latewood bands characteristic of flat-sawn or rough-hewn timber. Distinctive growth ring lines are visible even through the rough texture.
Color Description
Heartwood ranges from light brown to reddish-brown, often developing a deep orange or red patina over time. Sapwood is much lighter, almost white to pale yellow. This sample shows a warm, aged orange-brown hue.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; Douglas Fir is known for its strength-to-weight ratio and has some natural resistance to decay and rot, but is susceptible to insect attack without treatment.
Common Uses
Heavy dimensional construction, framing, flooring, cabinetry, interior joinery, and veneers. Common in historical timber framing and modern residential structures.
Geographic Origin
Native to Western North America (Pacific Northwest) and widely cultivated in Europe and New Zealand.
Market Value & Sustainability
Estimated Market Value
$3.00 - $6.00 per board foot depending on grade (Vertical Grain commands higher prices)
Wood Age Estimate
Estimated 40-70 years based on the heavy oxidation (orange patina) and the presence of older square-cut or industrial-grade fasteners and rough-milled industrial surfacing.
Sustainability Status
Least Concern; highly sustainable in North America with FSC certification widely available and extensive reforestation programs in place.
Workability
Generally works well with both hand and machine tools, though it can be prone to splintering and tearout due to the contrast between soft earlywood and hard latewood. It glues and finishes well but may require a sealer for even staining.
Notable Features
Distinctive resinous scent when freshly cut. High strength-to-weight ratio. Known for being the strongest and stiffest softwood in North America.
Finish Recommendations
Responds well to oil-based finishes which enhance the warm orange tones. Requires a sanding sealer or wood conditioner if staining to prevent blotchiness. Rough-sawn textures often benefit from penetrating oils or flat urethanes.
Identification Confidence
Medium; The color, texture, and growth ring patterns are highly indicative of Douglas Fir, though some variants of Southern Yellow Pine can appear similar in rough-sawn rustic applications.
