Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Straight and uniform with a medium to coarse texture; visible growth rings show contrast between earlywood and latewood. Appearance indicates a flat-sawn or rotary-cut veneer surface with some minor pin knots.
Color Description
Heartwood is typically a light reddish-brown or yellowish color; sapwood is lighter cream to yellowish. Color darkens with age and exposure to UV light toward a more orange-ish hue.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable - heartwood has moderate resistance to decay but is susceptible to insect attack. Common for construction but needs treatment for ground contact.
Common Uses
Structural framing, plywood veneers, heavy timber construction, flooring, window and door frames, and boat building.
Geographic Origin
Native to Western North America (Pacific Northwest)
Market Value & Sustainability
Estimated Market Value
$3.00 - $6.00 per board foot (standard grade); higher for clear vertical grain (CVG)
Wood Age Estimate
Modern sample, likely less than 5-10 years old based on lack of deep oxidation or heavy patina.
Sustainability Status
Least Concern (IUCN); widely available and sustainably managed; FSC certified options are common.
Workability
Generally easy to work with both hand and machine tools, though it can be prone to splintering and tear-out along grain lines. Sharp blades are required to avoid crushing the soft earlywood fibers.
Notable Features
Distinctive resinous scent when freshly cut. High strength-to-weight ratio for a softwood. Known for its stiffness and stability in structural applications.
Finish Recommendations
Takes stains and paints well, though a wood conditioner is recommended to prevent blotching on flat-sawn surfaces. Polyurethane and lacquer are standard for durability.
Identification Confidence
Medium-High; the coarse texture, distinct growth ring contrast visible in the fibers, and the specific reddish-orange hue are highly characteristic of Douglas Fir veneer.
