SPF (Spruce-Pine-Fir mix), likely Eastern White Pine or Spruce
Pinus strobus / Picea glauca • Softwood
Grain Pattern
Straight, with distinct annual growth rings showing a semi-abrupt transition from earlywood to latewood; large integrated knot present near the center.
Color Description
Pale creamy white to light yellowish heartwood with barely distinguishable sapwood. Minimal luster, will darken to a deeper amber/yellow over time with UV exposure.
Hardness Rating
380 lbf (Very Soft)
Durability Rating
Non-durable to Slightly Durable; low resistance to rot and insect attack if left untreated in outdoor environments.
Common Uses
General construction framing, 2x4 dimensional lumber, crates, pallets, and basic interior millwork.
Geographic Origin
Northern North America (Canada and Northern United States).
Market Value & Sustainability
Estimated Market Value
$0.60 - $1.20 per board foot (standard construction grade).
Wood Age Estimate
Freshly cut or modern stock (less than 5 years old) based on bright color, lack of oxidation, and rough-sawn mill marks.
Sustainability Status
Highly sustainable; common species not listed on CITES or IUCN Red List; widely available with FSC certification.
Workability
Very easy to work with both hand and machine tools; however, the soft nature makes it prone to denting and fuzzy surfaces if tools are not sharp. Glues and finishes well.
Notable Features
Mild, resinous scent; lightweight; contain resin canals which can sometimes lead to pitch bleed; visible "rough-back" fibers from high-speed commercial sawing.
Finish Recommendations
Water-based or oil-based polyurethane for protection; requires a wood conditioner before staining to prevent blotchiness due to uneven absorption.
Identification Confidence
High; the combination of ring structure, color, knot morphology, and the specific cross-section dimensions are characteristic of standard retail SPF lumber.
