Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Generally straight to slightly wavy with a coarse, uneven texture. The sample shows prominent latewood bands characteristic of flat-sawn or rotary-peeled veneer surfaces.
Color Description
Heartwood is typically a light reddish-brown; sapwood is yellowish-white. This sample shows significant oxidation (graying/weathering) and old paint residue, with some natural warmth remaining under the surface.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; resistant to decay but susceptible to insect attack. Common for external use if properly treated or maintained.
Common Uses
Sash, doors, windows, general millwork, plywood, veneer, and heavy structural timber/construction.
Geographic Origin
Western North America, primarily from the Rocky Mountains to the Pacific Coast.
Market Value & Sustainability
Estimated Market Value
$3.00 - $5.00 per board foot for select grades; significantly less for reclaimed structural material.
Wood Age Estimate
30-50 years based on the heavy oxidation, multiple layers of chipped lead-style paint, and the darkening of the exposed grain fibers.
Sustainability Status
Least Concern (IUCN); widely available as FSC certified and managed through sustainable forestry practices.
Workability
Generally easy to work with machine tools, though it can be prone to splintering and tearout during planing. It holds screws and nails well but may require grain sealing before finishing.
Notable Features
Distinctive resinous scent when freshly cut. High strength-to-weight ratio for a softwood. Known for prominent growth rings that can create a 'shell' effect when weathered.
Finish Recommendations
Requires careful sanding to remove old paint; an oil-based primer or clear sealer is recommended to prevent grain raising, followed by polyurethane or outdoor-rated varnish.
Identification Confidence
Medium-High. The contrast between earlywood and latewood bands, the reddish tint in the protected areas, and its use in what appears to be a door or panel frame are hallmarks of Douglas Fir.
