Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Straight, fine to medium grain; features prominent growth rings with a sharp transition from earlywood to latewood creating a distinct striped or 'cathedral' appearance on flat-sawn surfaces.
Color Description
Heartwood is typically a yellowish-tan to reddish-brown; sapwood is lighter cream to nearly white. Displays a medium luster and tends to darken/redden significantly with light exposure over time.
Hardness Rating
660 lbf (Soft to Medium-Soft)
Durability Rating
Moderately Durable; offers some resistance to decay but is susceptible to insect attack. Fairly resistant to rot compared to other architectural softwoods.
Common Uses
Heavy construction, framing, flooring, cabinetry, veneer, furniture, and boat building.
Geographic Origin
Western North America (Pacific Northwest regions of USA and Canada).
Market Value & Sustainability
Estimated Market Value
$3.00 - $7.00 per board foot depending on grade (Vertical Grain/Clear vs. Construction grade).
Wood Age Estimate
Based on the oxidation/patina and the rough-sawn end grain, this appears to be seasoned construction-grade lumber, likely 5-20 years old since Harvest.
Sustainability Status
Not listed on CITES or IUCN Red List; widely available as FSC certified and considered a highly sustainable, managed resource.
Workability
Generally works well with hand and machine tools, though it can be prone to splintering and tear-out. It glues and finishes well but is known for 'grain telegraphing' if not sanded properly.
Notable Features
Distinctive resinous scent when cut; high strength-to-weight ratio; notable for its ability to produce very large, straight-grained timbers.
Finish Recommendations
Takes stains and oils well; a sanding sealer or pre-stain conditioner is recommended to prevent blotchiness. Polyurethane provides a durable finish for high-wear areas.
Identification Confidence
High; the combination of the reddish-orange hue, prominent latewood bands visible in the end grain, and the splintering pattern at the break point is diagnostic for Douglas Fir.
