Grain Pattern

Coarse, mostly straight longitudinal grain; the rough, weathered end surface limits assessment of growth-ring and cut pattern. No distinctive figure is visible.

Color & Appearance

Exposed wood appears tan to brown, with a darker weathered surface and gray discoloration. Original heartwood and sapwood colors are obscured; light exposure can deepen and gray the surface.

Hardness (Janka)

Douglas-fir: about 660 lbf, Soft. Values vary by source and material.

Durability & Decay Resistance

Slightly Durable; untreated material has limited decay and insect resistance, especially outdoors.

Value & Age

Estimated Market ValueNot an official valuation

Typical construction-grade Douglas-fir commonly costs roughly US$2–6 per board foot retail; this rough piece's grade and value are uncertain.

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

Wood Age Estimate
Cannot reliably estimate age from this single weathered view; wear and discoloration indicate exposure, not the wood's age.

Common Uses

Framing, sheathing, beams, trim, doors, and general construction.

Geographic Origin

Native to western North America, especially the Pacific Northwest and western interior.

Workability

Generally machines and glues well, though coarse grain may splinter or tear out; use sharp tools and predrill near edges.

Finish Recommendations

Clean and dry thoroughly, sand to sound wood, then use an exterior-rated primer and paint or suitable penetrating finish if exposed outdoors.

Notable Features

A common structural softwood with prominent growth-ring contrast; no reliable scent or resin features are discernible here.
