1220 lbf (Hard)

Durability & Decay Resistance

Slightly durable to non-durable regarding decay resistance; vulnerable to insect attack and rot if exposed to moisture

Value & Sustainability

Estimated Market Value
3.00 to 6.00 USD per board foot depending on grade and region
Wood Age Estimate
Estimated to be relatively freshly milled or modern stock (less than 5 years old based on clean, unweathered surface)
Sustainability Status
Least concern, widely abundant, not listed on CITES appendices, readily available with FSC certification options

Common Uses

Flooring, furniture, cabinetry, interior millwork, and general construction

Geographic Origin

Eastern North America

Workability

Favorable workability; machines well, glues, stains, and finishes easily, though prone to splitting if nailed without pre-drilling due to hardness

Finish Recommendations

Accepts stains, polyurethane, lacquer, and oil finishes exceptionally well; grain filler is recommended if a completely smooth, level surface is desired

Notable Features

Open grain structure with large visible pores, moderate tannin content, distinctive reddish hue, porous end grain requiring pore filler for a smooth glass-like finish
