Grain Pattern
Tight vertical grain (quarter-sawn and rift-sawn), showing narrow, closely spaced growth rings typical of old-growth conifers.
Color & Appearance
Rich amber to reddish-brown heartwood with high color variation between boards, displaying a warm patina and moderate natural luster due to high resin content.
Hardness (Janka)
870 lbf (Medium)
Durability & Decay Resistance
Durable to Moderately Durable, featuring high natural resistance to rot and decay due to dense resin content.
Value & Sustainability
- Estimated Market Value
- 6.00 to 12.00 USD per board foot for reclaimed grade material.
- Wood Age Estimate
- Estimated 80 to 120+ years old, characteristic of antique reclaimed old-growth structural lumber with deep oxidation.
- Sustainability Status
- Old-growth longleaf pine forests are largely depleted, making reclaimed stock the primary sustainable source. Not CITES listed.
Common Uses
Flooring, structural framing, heavy construction, historical restoration, and fine furniture.
Geographic Origin
Southeastern United States (historically widespread across the coastal plains).
Workability
Generally easy to work with hand and machine tools, though high resin content can gum up saw blades and sandpaper.
Finish Recommendations
Penetrating oils, oil-based polyurethanes, or traditional wax finishes enhance the deep amber tones; ensure proper dewaxing or sealing if high resin bleeding is present.
Notable Features
Extremely high resin content, distinctive sweet pine scent when freshly cut, very tight growth rings indicating slow growth, and high density compared to modern plantation pine.
