Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Straight grain with a medium to coarse texture; visible growth rings showing a distinct transition between light-colored earlywood and darker latewood. This sample shows flat-sawn characteristics with some checking.
Color Description
Light brown to reddish-brown heartwood with a narrower yellowish-white sapwood. Substantial color variation between growth rings; tends to darken to a deeper reddish-tan over time with UV exposure.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; resistant to decay but susceptible to insect attack. Strongest under compression among softwoods.
Common Uses
Heavy construction, structural timber, framing, flooring, veneer, and boat building.
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 and vertical grain vs. flat-sawn.
Wood Age Estimate
Estimated 20-50 years based on the deep oxidation, surface patina, and drying checks consistent with reclaimed structural timber.
Sustainability Status
Not CITES listed; classified as Least Concern by IUCN. Widely available through FSC certified sources and sustainable forestry practices.
Workability
Generally easy to work with hand and machine tools, though it can be prone to splintering and tearout during machining. Responds well to glues and finishes but can have uneven stain absorption due to resin content.
Notable Features
Distinctive resinous scent when cut; high strength-to-weight ratio; high resin content which can cause pitch pockets.
Finish Recommendations
Penetrating oils or clear polyurethane are best to highlight the grain and provide protection. A wood conditioner is recommended before staining to prevent blotchiness.
Identification Confidence
High; the characteristic reddish-orange hue, prominent latewood bands, and specific checking patterns are classic indicators of Douglas Fir timber.
