SPF (Spruce-Pine-Fir) commercial lumber, likely White Spruce or Eastern White Pine
Picea glauca / Pinus strobus • Softwood
Grain Pattern
Predominantly straight grain with a medium to coarse texture; visible small tight knots and a flat-sawn face exhibiting subtle cathedral patterns in wetter/denser areas.
Color Description
Pale yellowish-white heartwood with nearly indistinguishable creamy sapwood; low luster with a rough-sawn surface that will yellow or darken to a golden tan over time with UV exposure.
Hardness Rating
380-420 lbf (Very Soft)
Durability Rating
Non-durable to Slightly Durable; low resistance to decay and insect attack if left untreated in exterior conditions.
Common Uses
General construction framing, dimensional lumber, pallets, crates, and basic DIY utility projects.
Geographic Origin
Northeastern United States and across Canada (Transcontinental Spruce-Hardwood Boreal Forest).
Market Value & Sustainability
Estimated Market Value
Approximately $0.75 - $1.50 per board foot depending on local dimensional lumber prices.
Wood Age Estimate
Freshly milled or relatively new stock (less than 1 year); shows minimal oxidation or patina, exhibiting typical kiln-dried brightness.
Sustainability Status
Not listed on CITES or IUCN Red List; widely available, FSC certified, and considered a highly sustainable renewable building resource.
Workability
Easy to work with both hand and machine tools; very easy to nail and screw, though can be prone to splintering on rough-sawn edges and some pitch buildup on blades.
Notable Features
Mild resinous scent when cut; lightweight with a high strength-to-weight ratio for its density; may contain small resin canals.
Finish Recommendations
Best suited for paint or solid stains in construction; if used for furniture, a wood conditioner is recommended before staining to prevent blotching.
Identification Confidence
High; the rough-sawn texture, pale color without distinct heartwood contrast, and presence of small knots are characteristic of commercial SPF graded dimensional lumber.
