Southern Yellow Pine
Pinus spp. (likely Pinus taeda) • Softwood
Grain Pattern
Straight but coarse with distinct growth rings; flat-sawn orientation showing cathedral patterns typical of construction lumber.
Color Description
Yellowish-white to tan sapwood with light reddish-brown heartwood. This sample shows the greenish-yellow hue characteristic of copper-based pressure treatment (ACQ or MCA).
Hardness Rating
690 lbf (Soft)
Durability Rating
Durable (due to pressure treatment); naturally non-durable to slightly durable without chemical protection. High rot and insect resistance after treatment.
Common Uses
Outdoor construction, fencing, decking, framing, utility poles, and landscaping.
Geographic Origin
Southeastern United States.
Market Value & Sustainability
Estimated Market Value
$1.50 - $2.50 per board foot (standard dimensional treated lumber price).
Wood Age Estimate
Fresh/New (Under 1 year); shows minimal weathering, light coloration, and sharp factory edges consistent with recent installation.
Sustainability Status
Highly sustainable; abundant in the US, widely farmed on plantations, and not listed on CITES or IUCN Red List.
Workability
Easy to work with both hand and machine tools. Resinous nature can gum up sandpaper and blades; requires corrosion-resistant fasteners (hot-dipped galvanized or stainless steel) due to treatment chemicals.
Notable Features
Distinctive resinous smell; specifically treated for ground contact or exterior use; high strength-to-weight ratio for a softwood.
Finish Recommendations
Allow to dry (season) for several months until moisture content drops before applying oil-based stains or exterior-grade sealants.
Identification Confidence
High; identification based on the visible growth ring structure typical of Southern Yellow Pine combined with the distinctive green tint of pressure-treating chemicals used for fence rails.
