Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Generally straight with conspicuous growth rings. Exhibits flat-sawn cathedral patterns on faces and prominent darker latewood bands. Occasional small, tight knots as seen in this sample.
Color Description
Heartwood is typically a light reddish-brown to orange-yellow. Sapwood is a lighter white to pale yellow. This sample shows a fresh, light orange-hued heartwood that will darken and redden with light exposure.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; heartwood shows moderate resistance to rot and decay but is susceptible to insect attack. Not suitable for direct ground contact without treatment.
Common Uses
Structural framing, heavy construction, flooring, cabinetry, veneer, and trim work. Highly valued for its strength-to-weight ratio.
Geographic Origin
Western North America (Pacific Northwest, Rocky Mountains) and widely planted in Europe and New Zealand.
Market Value & Sustainability
Estimated Market Value
$3.00 - $6.00 per board foot depending on grade (Vertical Grain/Select vs. Construction Grade).
Wood Age Estimate
Freshly milled/cut lumber. The lack of oxidation and graying suggests the wood was surfaced within the last 3-6 months.
Sustainability Status
Least Concern on IUCN Red List; widely available with FSC certification; considered a highly sustainable commercial timber species.
Workability
Generally works well with both hand and machine tools, though it can be brittle and prone to splintering. It has a tendency to tear out during planing and requires sharp blades. Takes glue and finish well.
Notable Features
Distinctive resinous, sweet balsamic scent when cut. High resin content can occasionally cause gumming of tools or finish issues if not dried properly. High strength-to-weight ratio for a softwood.
Finish Recommendations
Polyurethane, lacquer, or oil-based finishes. A sanding sealer or shellac pre-coat is recommended to prevent uneven absorption of stains due to the density difference between earlywood and latewood.
Identification Confidence
High. The distinct contrast between the light earlywood and dark latewood, the orange-red color profile, the specific knot structure, and the apparent density are characteristic of Douglas Fir.
