Grain Pattern

Straight to slightly irregular grain with prominent growth rings showing mixed flat-sawn and quarter-sawn patterns, characteristic of narrow strip flooring.

Color & Appearance

Hardness (Janka)

1360 lbf (Hard)

Durability & Decay Resistance

Durable, with very good resistance to rot and fungal decay due to closed cellular structure (tyloses).

Value & Sustainability

Estimated Market Value
$6 to $12 per board foot for standard lumber, higher for salvaged/reclaimed flooring grades.
Wood Age Estimate
Estimated to be 80 to 120 years old, typical of turn-of-the-century or early-to-mid 20th-century residential strip flooring.
Sustainability Status
Abundant, widely distributed, not listed on CITES appendices, and of least concern on the IUCN Red List.

Common Uses

Flooring, furniture, cabinetry, boat building, and tight cooperage.

Geographic Origin

Eastern North America

Workability

Generally easy to work with both hand and machine tools, though it can blunt cutting edges due to density. Glues, stains, and finishes well.

Finish Recommendations

Polyurethane, penetrating oils, or traditional shellac and wax. Pre-finishing sanding is required to remove surface wear and old oxidation layers.

Notable Features

High tannin content which reacts strongly with iron; closed cellular structure containing tyloses making it water-resistant.
