Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Growth ring pattern exhibiting a mix of tight and wide latewood bands; end-grain shows distinct annual rings with a fairly abrupt transition from earlywood to latewood. The surface shows some circular growth figure due to the cookie cut.
Color Description
Heartwood is typically a light reddish-brown to yellowish-tan, while the sapwood is a narrower band of pale white to yellowish-cream. It tends to darken or redden over time with exposure to UV light.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable to Slightly Durable; generally resistant to decay but susceptible to insect attack if left untreated in ground contact.
Common Uses
Heavy construction, framing, flooring, sashes, doors, furniture, and boat building.
Geographic Origin
Western North America (Pacific Northwest)
Market Value & Sustainability
Estimated Market Value
$3.00 - $6.00 per board foot depending on grade and vertical grain quality.
Wood Age Estimate
The visible growth rings suggest the tree section was approximately 35-45 years old when harvested; the surface oxidation suggests this cut is relatively fresh, likely less than 2 years old.
Sustainability Status
Least Concern (IUCN); widely available and frequently FSC certified due to extensive plantation forestry.
Workability
Generally works well with both hand and machine tools, though it can be prone to splintering or tearing during surfacing. It glues and finishes well but may require a sealer for even staining.
Notable Features
Distinctive resinous scent when cut; high strength-to-weight ratio; clear distinction between light earlywood and dark latewood rings.
Finish Recommendations
Penetrating oils or clear polyurethane are recommended to highlight the natural grain contrast. If staining, a pre-stain wood conditioner is advised to prevent blotching.
Identification Confidence
High; the distinct reddish-orange heartwood, narrow pale sapwood, and specific growth ring characteristics are classic markers of Pseudotsuga menziesii.
