Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Straight, dense grain with a distinct vertical orientation. Shows prominent latewood/earlywood contrast (ringing) typical of flat-sawn or slightly rift-sawn construction lumber.
Color Description
Light brown to reddish-tan heartwood with yellowish-white sapwood. Shows a slight orange/red hue common in the species; darkens to a more pronounced reddish-brown with exposure to UV light and air.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; offers some natural resistance to rot and decay compared to other softwoods, but remains susceptible to insect attack without treatment.
Common Uses
Structural framing, heavy timbers, plywood, flooring, cabinets, and exterior millwork.
Geographic Origin
Western North America (Pacific Northwest through the Rocky Mountains).
Market Value & Sustainability
Estimated Market Value
$1.50 - $3.00 per board foot (varies significantly between framing grade and select structural/vertical grain clear).
Wood Age Estimate
Relatively young lumber (likely 1-5 years post-harvest). The crisp edges and lack of deep gray oxidation suggest it is recently milled construction-grade material.
Sustainability Status
Not listed on CITES Appendices or the IUCN Red List; widely available and frequently FSC certified as it is a major commercial timber species in North America.
Workability
Generally easy to work with machine and hand tools. However, the hard latewood bands can cause uneven sanding and can be prone to splintering. Glues, stains, and finishes well.
Notable Features
Distinctive sweet/resinous scent when cut. High strength-to-weight ratio makes it the preferred softwood for structural applications.
Finish Recommendations
Oil-based stains or clear polyurethanes. A pre-stain wood conditioner is recommended to prevent blotching due to the variations in grain density.
Identification Confidence
High. The prominent latewood lines, specific orange-red undertones, and fiber texture are classic identifiers for Douglas Fir construction lumber.
