Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Straight grain with distinct, prominent growth rings. This sample shows a flat-sawn face with some cathedral patterns and visible tight knots.
Color Description
Heartwood is a warm reddish-brown to orange color; sapwood is much lighter yellowish-white. The wood will darken and redden over time when exposed to UV light.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; good resistance to decay but susceptible to insect attack without treatment.
Common Uses
Structural framing, exterior posts, decking, flooring, glue-laminated beams (glulams), and heavy timbers.
Geographic Origin
Western North America (Pacific Northwest)
Market Value & Sustainability
Estimated Market Value
$2.50 to $4.50 per board foot for standard construction grade.
Wood Age Estimate
Newer construction; likely harvested within the last 5-10 years based on fresh color and modern dimensional milling.
Sustainability Status
Not listed on CITES or IUCN Red List; widely available and frequently FSC certified.
Workability
Generally easy to work with both hand and machine tools, though latewood can be hard and brittle, leading to tearout during planning; glues and finishes well.
Notable Features
Distinctive resinous scent when cut; known for having one of the highest strength-to-weight ratios of any softwood.
Finish Recommendations
Penetrating oil-based stains or film-forming clear coats like exterior-grade polyurethane to prevent UV graying.
Identification Confidence
High; the distinct separation between earlywood and latewood bands, reddish hue, and use as an exterior structural post are hallmark traits.
