Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Generally straight with a medium to coarse texture; visible latewood bands create a high-contrast plain-sawn appearance with wavy grain lines common in construction grade material.
Color Description
Heartwood is typically a light yellowish-tan to reddish-brown; sapwood is a paler cream color. It darkens significantly upon exposure to UV light, developing a deeper orange-red patina.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; resistance to decay is moderate but susceptible to insect attack. It is highly valued for structural stability.
Common Uses
Plywood, veneer, construction/structural framing, flooring, boat building, and exterior trim.
Geographic Origin
Western North America (Pacific Northwest to British Columbia).
Market Value & Sustainability
Estimated Market Value
$2.50 to $5.50 per board-foot depending on grade (Vertical Grain vs. Flat Sawn).
Wood Age Estimate
Freshly milled to slightly seasoned (less than 1 year); shows minimal oxidation and typical rough-sawn mill marks.
Sustainability Status
Least Concern (IUCN); widely available and harvested from sustainably managed forests; FSC certification is common.
Workability
Generally easy to work with both machine and hand tools; can be prone to splintering and tearout if tools are not sharp. Holds nails and screws well but may require pre-drilling near ends.
Notable Features
Distinctive resinous, sweet scent when cut; high strength-to-weight ratio; susceptible to pitch pockets.
Finish Recommendations
Responds well to most finishes; however, a wood conditioner or sealer is recommended before staining to prevent blotching due to density variations.
Identification Confidence
High; the distinctive reddish-orange hue, prominent latewood growth rings, and characteristic rough-sawn texture are hallmark traits of North American Douglas Fir.
