Grain Pattern
Straight grain with distinct growth rings visible on the face, characteristic of a flat-sawn or rift-sawn cut.
Color & Appearance
Light reddish-brown to yellowish-orange heartwood with a paler yellowish sapwood. Exhibits a natural golden luster that darkens somewhat with exposure to light over time.
Hardness (Janka)
660 lbf (Soft)
Durability & Decay Resistance
Moderately durable, with fair resistance to decay, though susceptible to insect attack if left untreated.
Value & Sustainability
- Estimated Market Value
- Moderately low cost, approximately $2.50 to $5.00 per board foot depending on grade and dimensions.
- Wood Age Estimate
- Estimated to be relatively recent (freshly cut or milled within the last few months to a year) based on bright coloring and lack of heavy oxidation.
- Sustainability Status
- Not listed on CITES appendices or IUCN Red List. Widely available from sustainably managed forests and plantations.
Common Uses
Construction framing, plywood, structural lumber, flooring, doors, and general millwork.
Geographic Origin
Western North America, particularly the Pacific Northwest.
Workability
Generally easy to work with both hand and machine tools, though the sharp contrast in hardness between earlywood and latewood can occasionally cause splintering or uneven planing.
Finish Recommendations
Accepts stains and clear finishes (such as polyurethane or lacquer) well, though pre-conditioning may be required for even stain absorption on the softer earlywood.
Notable Features
High strength-to-weight ratio, distinct resin canals, and a pronounced grain contrast between earlywood and latewood zones.
