Southern Yellow Pine
Pinus spp. (likely Pinus palustris or Pinus taeda) • Softwood
Grain Pattern
Straight but coarse with a prominent cathedral pattern on flat-sawn faces. High contrast between earlywood and latewood growth rings creates a ribbed texture on weathered surfaces.
Color Description
Heartwood is typically reddish-brown, while sapwood is yellowish-white. This sample shows deep silver-grey to black oxidation and weathering (patina) due to outdoor exposure.
Hardness Rating
690 lbf (Soft to Medium - varies significantly by specific species)
Durability Rating
Moderately Durable; heartwood has some natural resistance to decay, but untreated sapwood is susceptible to rot and insect attack in ground-contact scenarios.
Common Uses
Residential construction, heavy framing, decking, flooring, crates, and pressure-treated lumber for outdoor use.
Geographic Origin
Southeastern United States
Market Value & Sustainability
Estimated Market Value
$1.50 - $2.50 per board foot (standard grade); reclaimed value may be slightly higher if structural integrity is maintained.
Wood Age Estimate
20-40 years since harvest. The deep grey oxidation and rounding of edges suggest long-term outdoor exposure (10+ years), likely as part of a salvaged structure or deck.
Sustainability Status
Not listed on CITES or IUCN Red List; widely available and considered highly sustainable due to fast growth and extensive plantation management.
Workability
Generally easy to work with hand and machine tools, though high resin content can gum up blades and sandpaper. It holds screws and nails well but can split if not pre-drilled near edges.
Notable Features
Distinctive resinous/turpentine scent when cut; high contrast in ring density; high strength-to-weight ratio for a softwood.
Finish Recommendations
Requires thorough cleaning/sanding if reusing. For outdoor use, a high-quality oil-based stain or UV-resistant sealer; for indoor use, polyurethane or shellac after removing surface oxidation.
Identification Confidence
High; the wide growth rings with very distinct, dark latewood bands seen on the end-grain and the typical weathering patterns are characteristic of Southern Yellow Pine utility lumber.
