Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Straight, tight, and relatively uniform grain. The sample shows flat-sawn characteristics with some visible knots and checking along the center line.
Color Description
Heartwood is typically a range of light brown to reddish-brown; sapwood is yellowish-white. This specific weathered sample shows a greyish patina due to oxidation and heavy surface wear.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; offers some resistance to decay but is susceptible to insect attack if left untreated in ground contact.
Common Uses
Structural framing, heavy construction, flooring, boat building, exterior joinery, and reclaimed furniture.
Geographic Origin
Western North America (Pacific Northwest)
Market Value & Sustainability
Estimated Market Value
$5.00 - $12.00 per board foot for high-quality reclaimed old-growth boards.
Wood Age Estimate
Old-growth reclaimed timber, likely 50-100+ years old based on the density of growth rings and heavy surface oxidation.
Sustainability Status
Least Concern (IUCN); widely available as FSC certified, though old-growth is primarily sourced through reclamation.
Workability
Generally works well with both hand and machine tools, though it can be prone to splintering and edge tear-out. Glues and finishes well.
Notable Features
Distinctive resinous scent when freshly cut. High strength-to-weight ratio for a softwood. Notable for its large available dimensions in structural beams.
Finish Recommendations
Deep-penetrating oils or clear polyurethanes. For weathered reclaimed looks, a light sanding followed by a matte wax or water-based finish is recommended.
Identification Confidence
Medium-High; the growth ring density, color transition in worn areas, and common use as structural planking strongly suggest Douglas Fir over Pine or Larch.
