Pseudotsuga menziesii · Softwood (conifer)

AI-generated identification · may be incorrect
Type
Softwood (conifer)
Origin
Native to western North America, especially the Pacific Northwest and interior western mountain regions.
Hardness
Janka approximately 620 lbf — Soft.
Durability
Slightly durable; heartwood has limited resistance to decay and insects, while sapwood is readily vulnerable outdoors.

Grain Pattern

Predominantly straight, pronounced earlywood/latewood growth bands, with flat-sawn cathedral patterns and occasional knots; no notable decorative figure.

Color & Appearance

Pinkish tan to orange-brown heartwood with paler sapwood; moderate luster and strong growth-ring contrast. It generally darkens slightly and becomes warmer brown with age and light.

Hardness (Janka)

Janka approximately 620 lbf — Soft.

Durability & Decay Resistance

Slightly durable; heartwood has limited resistance to decay and insects, while sapwood is readily vulnerable outdoors.

Value & Age

Estimated Market ValueNot an official valuation

About $3–$8 per board foot for ordinary clear/select stock; reclaimed or exceptionally clear material 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 boards appear relatively recent, likely kiln-dried construction or interior stock; visible surface weathering is insufficient to establish actual tree age.

Common Uses

Framing, beams, siding, doors, flooring, cabinetry, trim, plywood, and general construction lumber.

Geographic Origin

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

Workability

Machines and hand-tools fairly well, though resin, pronounced hardness contrast, and occasional knots can cause tearout or uneven planing. Sands, glues, and fastens readily; predrilling helps near edges.

Finish Recommendations

Sand uniformly and seal knots or resinous areas before applying oil, lacquer, shellac, or polyurethane. Clear finishes emphasize the ring contrast; a conditioner or washcoat can reduce uneven absorption.

Notable Features

Distinctive strong growth-ring contrast, moderate weight, and resinous conifer scent when freshly cut; the pictured material resembles vertical-grain/flat-sawn Douglas-fir boards.
