Grain Pattern

Predominantly straight, flat-sawn grain with pronounced earlywood/latewood banding and broad cathedral-like arcs; no distinctive decorative figure visible.

Color & Appearance

Aged reddish-brown to gray-brown surface with darker streaks and weathering; fresh Douglas fir is typically yellow-orange to salmon-brown and darkens with exposure.

Hardness (Janka)

620 lbf Janka; Soft.

Durability & Decay Resistance

Slightly durable: limited natural resistance to prolonged exterior decay and insects, especially where moisture is retained.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $2–$6 per board foot for ordinary reclaimed/weathered material; selectively clear or old-growth stock may cost more.

AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.

Wood Age Estimate
The board’s patina and checking suggest years of outdoor exposure, perhaps 10–30 years; the tree’s biological age cannot be determined visually.

Common Uses

Framing, decking, siding, beams, doors, furniture, and general construction lumber.

Geographic Origin

Native to western North America, especially British Columbia, the Pacific Northwest, and California.

Workability

Generally machines, planes, sands, glues, and fastens easily, though resin, knots, and uneven grain can cause tear-out or blade loading.

Finish Recommendations

Remove loose fibers, clean, sand, and apply an exterior penetrating oil or stain; film finishes require very dry, stable wood and careful preparation.

Notable Features

Visible growth-ring contrast, resinous character, knots, and substantial surface checking typical of weathered softwood.
