Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Strong, prominent flat-sawn cathedral patterns with distinct transitions between light earlywood and dark latewood; generally straight but featuring wide growth rings.
Color Description
Heartwood is a light reddish-brown to orange-brown with pale yellowish sapwood. It typically darkens to a more pronounced reddish-orange with age and UV exposure.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; offers some resistance to decay but is susceptible to insect attack and rot if in direct ground contact without treatment.
Common Uses
Structural framing, heavy timber construction, veneers, flooring, cabinetry, and exterior millwork.
Geographic Origin
Western North America, primarily the Pacific Northwest and Rocky Mountains.
Market Value & Sustainability
Estimated Market Value
Approximately $2.00 to $4.50 per board foot depending on grade and regional availability.
Wood Age Estimate
Relatively modern (less than 10 years); the wood lacks heavy oxidation, silvering, or deep patina, suggesting it is newer construction-grade stock.
Sustainability Status
Least Concern (IUCN); widely available and frequently FSC certified as it is one of the most sustainably managed timber species in North America.
Workability
Generally works well with machine tools but can be prone to splintering and tearout during planing. It sands easily and holds nails/screws well, though the hard latewood can cause bit deflection.
Notable Features
Distinctive resinous, sweet citrus-like scent when freshly cut; highest strength-to-weight ratio among commercial softwoods; high resin content.
Finish Recommendations
Takes stains reasonably well but benefits from a sanding sealer or pre-stain conditioner to prevent blotchiness. Oil-based polyurethanes or lacquers are common for interior use.
Identification Confidence
High: The wide growth rings, distinct orange-red latewood cathedrals, and overall texture are classic identifiers of Coast Douglas Fir construction timber.
