Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Generally straight with a medium to coarse texture; visible prominent growth rings show a distinct transition between lighter earlywood and darker latewood. This sample shows flat-sawn characteristics with some slight wavy figure.
Color Description
Heartwood ranges from a light orangey-brown to a deep reddish-brown depending on age and location. Sapwood is typically a pale cream to yellowish white. It darkens significantly over time into a deep reddish-orange when exposed to UV.
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
Heavy structural construction, flooring, veneer, cabinetry, boat building, and window frames.
Geographic Origin
Western North America, primarily the Pacific Northwest.
Market Value & Sustainability
Estimated Market Value
$3.00 - $6.00 per board foot depending on grade (clear vertical grain commands higher prices).
Wood Age Estimate
Freshly milled to recently seasoned (less than 1 year); shows bright oxidation and lacks deep patina or historical tool marks.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available with FSC certification and considered highly sustainable.
Workability
Generally easy to work with both hand and machine tools, though it can split during nailing or screwing. It sanded well but can have 'chip-out' or 'splintering' on the latewood bands.
Notable Features
Distinctive resinous scent when worked; high strength-to-weight ratio; susceptible to pitch pockets which can bleed through finishes.
Finish Recommendations
Takes stains and clear coats well, but a pre-stain wood conditioner is recommended to prevent blotchiness. Spar varnish or polyurethane is best for durability.
Identification Confidence
High; the distinctive growth ring contrast, reddish-tan hue, and fibrous texture visible on the cut edges are diagnostic of coastal Douglas Fir.
