Grain Pattern
Straight grain with distinct growth rings visible from rough-sawn circular or band saw marks
Color & Appearance
Light brown to reddish-brown heartwood with a lighter yellowish-white sapwood, moderate natural luster, darkens slightly to a deep reddish-brown with age and UV exposure
Hardness (Janka)
710 lbf (Soft)
Durability & Decay Resistance
Moderately durable, with fair resistance to decay and weathering depending on the heartwood content
Value & Sustainability
- Estimated Market Value
- 3.00 to 6.00 USD per board foot depending on grade and dimensions
- Wood Age Estimate
- Estimated to be moderately weathered, likely several decades old based on surface oxidation and rough-sawn texture
- Sustainability Status
- Not listed on CITES appendices or IUCN red list, widely available as plantation-grown and sustainably managed timber
Common Uses
Construction framing, heavy timber construction, plywood, flooring, doors, and veneer
Geographic Origin
Western North America, particularly the Pacific Northwest
Workability
Generally easy to work with both hand and machine tools, though it has a tendency to splinter or tear out during planing if tools are not sharp due to the varying hardness between earlywood and latewood
Finish Recommendations
Takes stains and finishes well, though oil-based finishes or exterior sealers are recommended to highlight the grain and protect against UV degradation
Notable Features
High strength-to-weight ratio, distinct contrast between earlywood and latewood bands, characteristic resin canals
