Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Predominantly straight grain with prominent, tight vertical grain (quarter-sawn/rift-sawn appearance). Growth rings are distinct with a sharp transition between light earlywood and dark latewood.
Color Description
Heartwood is typically a light reddish-brown to orange-brown. Sapwood is a pale yellowish-white. This sample shows a warm, amber-toned patina common in older, light-exposed installations. It exhibits moderate luster.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; offers some resistance to rot and decay but is susceptible to insect attack if untreated.
Common Uses
Flooring (vertical grain), heavy construction, bridge timbers, sash and door manufacturing, cabinetry, and plywood.
Geographic Origin
Western North America, primarily the Pacific Northwest and Coastal regions.
Market Value & Sustainability
Estimated Market Value
Approximately $8.00 - $15.00 per board foot for high-grade vertical grain (CVG) reclaimed or clear stock.
Wood Age Estimate
30 to 70 years based on the tight growth ring density (old-growth characteristic) and the deepened oxidization/ambering of the finish and fibers.
Sustainability Status
Not CITES listed; classified as Least Concern by IUCN. Widely available through FSC certified sources and sustainable forestry practices.
Workability
Generally works well with both hand and machine tools, though it has a tendency to splinter or develop 'shell-out' between growth rings. Glues and finishes well.
Notable Features
Distinctive resinous scent when freshly cut; exceptional strength-to-weight ratio; high levels of tannins can cause iron staining if wet nails are used.
Finish Recommendations
Polyurethane or oils are recommended to highlight the grain. Periodic maintenance with wax or oil is common for flooring to prevent drying and splintering.
Identification Confidence
High; the tight, straight vertical grain and the specific contrast between the earlywood and latewood bands are diagnostic of Douglas Fir flooring.
