Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable to Durable; shows good resistance to rot but is susceptible to insect attack.
Common Uses
Veneer, plywood, structural timbers, flooring, furniture, trim, 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 (Vertical Grain commands a premium).
Wood Age Estimate
Modern (under 20 years); the surface shows minimal oxidation patina and appears to have a modern clear protective finish.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available as FSC Certified and considered a sustainable choice.
Workability
Generally easy to work with hand and machine tools, though it can exhibit splintering or tear-out when working with knots. Dulls cutters moderately; glues and finishes well.
Notable Features
Features a distinct, resinous, sweet scent when worked. High strength-to-weight ratio makes it one of the strongest softwoods. High resin content can sometimes cause finishing issues if not sealed.
Finish Recommendations
Polyurethane, varnish, or lacquer provide good protection. A sanding sealer is recommended to prevent uneven staining on the earlywood/latewood transitions.
Identification Confidence
High; the distinctive contrast between the light earlywood and the dark, well-defined reddish-brown latewood bands is a hallmark of Douglas Fir.
