Color Description
Light reddish-brown to yellowish-tan heartwood with lighter creamy sapwood. Shows typical darkening toward an amber/orange hue with age and UV exposure.
Hardness Rating
620-710 lbf (Soft)
Durability Rating
Slightly durable to non-durable; poor rot and insect resistance without chemical treatment.
Common Uses
Residential construction, framing, structural lumber, palettes, and utility shelving.
Geographic Origin
North America (Pacific Northwest and Canada)
Market Value & Sustainability
Estimated Market Value
$0.50 - $1.20 per board foot (Commodity lumber prices)
Wood Age Estimate
Relatively young lumber, likely milled within the last 5-10 years based on minimal oxidation and modern mill marks.
Sustainability Status
Highly sustainable; widely available as FSC certified and managed through large-scale North American forestry.
Workability
Easy to work with both hand and machine tools, though susceptible to splintering and tearout around knots. Glues and nails well.
Notable Features
Mild resinous scent when cut; lightweight with a high strength-to-weight ratio for construction purposes.
Finish Recommendations
Accepts paint and solid stains well. Clear coats may require a wood conditioner to prevent blotchiness due to uneven resin distribution.
Identification Confidence
Medium-High; the grain structure, knot style, and reddish-tan color are characteristic of commercial structural softwoods found in North American hardware stores.
