SPF (Spruce-Pine-Fir mix), likely White Spruce or Lodgepole Pine
Picea glauca / Pinus contorta • Softwood
Grain Pattern
Straight, fine-textured grain with a flat-sawn orientation; visible growth rings indicate moderate growth speed; presence of a small sound knot on the left edge.
Color Description
Pale yellowish-white to light light brown heartwood with little to no distinction from sapwood. Low luster; typically yellows or darkens to a golden tan over time with UV exposure.
Hardness Rating
420 - 510 lbf (Very Soft to Soft)
Durability Rating
Non-durable; low resistance to decay and highly susceptible to insect attack if left untreated or in contact with ground moisture.
Common Uses
General construction framing, dimensional lumber, pallets, crates, plywood, and pulpwood for paper.
Geographic Origin
Northern regions of North America, primarily Canada and Northern United States.
Market Value & Sustainability
Estimated Market Value
$0.60 - $1.20 per board foot (standard commodity construction grade)
Wood Age Estimate
Recently harvested/milled; the wood shows fresh, light oxidation, clear saw marks (fuzzing/tear-out), and no significant silvering or deep patina typical of old reclaimed wood.
Sustainability Status
Highly sustainable; widely available, managed forests, not CITES listed, and generally considered IUCN Least Concern.
Workability
Easy to work with both hand and machine tools; however, the soft fibers can lead to 'fuzzing' or tear-out if blades are dull (as seen on the rough edges of the sample). Glues and finishes well.
Notable Features
Mild resinous scent; lightweight with a high strength-to-weight ratio for its density; prone to splintering at edges where cross-cut.
Finish Recommendations
Usually left unfinished for framing; for decorative use, a wood conditioner is recommended before staining to prevent blotchiness. Accepts paint, polyurethane, and water-based finishes well.
Identification Confidence
High; the combination of pale color, tight softwood grain, characteristic knot structure, and rough-milled 'fuzzed' edges is diagnostic of SPF dimensional construction lumber.
