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 10 to 30 years old, showing moderate weathering, surface checking, and environmental exposure typical of outdoor decking or architectural elements.
- Sustainability Status
- Generally abundant and sustainable, widely managed through tree farms and plantations in North America. Not listed on CITES appendices.
Common Uses
Construction framing, structural plywood, exterior decking, flooring, and doors.
Geographic Origin
Western North America and the Pacific Northwest.
Workability
Generally easy to work with both hand and machine tools, though the strong hardness contrast between earlywood and latewood can occasionally cause splintering or uneven planing if tools are not sharp.
Finish Recommendations
Exterior penetrating oils, semi-transparent stains, or exterior-grade polyurethane work best to protect against UV degradation and weathering.
Notable Features
High strength-to-weight ratio, distinct contrast between springwood and summerwood rings, and a slight resinous scent.
