Yellow Pine (likely Southern Yellow Pine)
Pinus echinata • Softwood
Grain Pattern
Straight but coarse with distinct latewood bands; present flat-sawn cathedral patterns visible around knots; includes a large tight knot and some blue-stain fungal figure
Color Description
Natural heartwood is reddish-brown while sapwood is yellowish-white; this sample shows significant graying/weathering and 'blue stain' caused by fungi; luster is low due to surface oxidation
Hardness Rating
690 lbf (Soft)
Durability Rating
Slow to moderately durable; heartwood has some rot resistance but sapwood is susceptible to decay and insect attack if untreated
Common Uses
Construction lumber, pallets, framing, utility shelving, exterior decking (if pressure treated), and heavy-duty crating
Geographic Origin
Southeastern United States
Market Value & Sustainability
Estimated Market Value
$1.00 - $1.50 per board foot (standard utility grade)
Wood Age Estimate
2-5 years since milling based on rough texture, typical pallet-grade oxidation, and fungal staining characteristics
Sustainability Status
Highly sustainable; widely available and not CITES listed; commonly FSC certified
Workability
Easy to work with both hand and machine tools; high resin content can gum up sandpaper and saw blades; prone to splitting when nailing near ends
Notable Features
Distinctive resinous/pine scent; contains noticeable 'blue stain' (fungal discoloration) which does not affect structural integrity; very high resin content
Finish Recommendations
Penetrating oil or polyurethane if used indoors; needs pressure treatment or exterior-grade sealant if used outdoors due to sapwood content
Identification Confidence
High - the combination of prominent growth rings, large resinous knots, overall color, and blue-stain patterns is characteristic of utility-grade Southern Yellow Pine common in pallet construction
