Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Straight grain with very prominent, flat-sawn latewood bands (cathedral figure potential). Shows a distinct transition between earlywood and latewood rings, typical of many conifers.
Color Description
Light brown to reddish-brown heartwood with a paler yellowish-white sapwood. This sample shows weathering gray streaks and oxidation, which is common as it ages under light or moisture exposure.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable. While it has some natural resistance to rot, it is susceptible to insect attack and will decay if in constant contact with ground moisture without treatment.
Common Uses
Structural framing, heavy construction, utility lumber (pallets/crates as seen here), flooring, trim, and plywood.
Geographic Origin
Western North America (Pacific Northwest, Rocky Mountains)
Market Value & Sustainability
Estimated Market Value
$1.50 - $4.00 per board foot (standard construction grade vs. vertical grain select)
Wood Age Estimate
The lumber itself appears recently milled (within 1-3 years), but the graying/dirt suggests it has been outdoors for several months.
Sustainability Status
Least Concern (IUCN). Generally considered sustainable due to massive reforestation programs and FSC availability in North America.
Workability
Easy to work with both hand and machine tools. It holds nails and screws well but can split if nailed near the ends. Resin can occasionally gum up blades.
Notable Features
Distinctive resinous scent when cut. Known for having one of the highest strength-to-weight ratios among softwoods. Possible minor skin irritation from splinters.
Finish Recommendations
Penetrating oils or stains work best. If painting, a primer is necessary to prevent tannin/pitch bleed. For outdoor use, a UV-inhibiting sealer is recommended to prevent graying.
Identification Confidence
High. The wide dark/light growth ring contrast, the texture of the splintering edges, and the specific reddish-orange hue are hallmark identifiers of Douglas Fir lumber used in utility applications.
