Grain Pattern

Straight grain with distinct growth rings showing alternating bands of earlywood and latewood, typical of flat-sawn dimensional lumber with minor knots.

Color & Appearance

Light yellowish-brown to reddish-brown heartwood with lighter yellowish sapwood, showing surface weathering, oxidation, and signs of previous finishing or staining that has aged.

Hardness (Janka)

690 lbf (Soft)

Durability & Decay Resistance

Moderately Durable

Value & Sustainability

Estimated Market Value
3.00 to 6.00 USD per board foot for standard dimensional lumber.
Wood Age Estimate
Estimated 5 to 15 years based on surface wear, weathering, and exposure patterns typical of outdoor decking.
Sustainability Status
Highly sustainable, widely planted and harvested on tree farms throughout the southeastern United States with abundant commercial availability.

Common Uses

Decking, construction, framing, flooring, and exterior applications.

Geographic Origin

Southeastern United States

Workability

Generally easy to work with both hand and machine tools, though the strong contrast between soft earlywood and hard latewood can sometimes cause uneven planing or sanding if tools are not sharp.

Finish Recommendations

Exterior semi-transparent penetrating stains or exterior sealers work best for outdoor applications like decking. Surface preparation requires cleaning and light sanding to remove weathered fibers.

Notable Features

High resin content, strong distinct grain contrast, characteristic pine scent when freshly cut, and good dimensional stability when properly treated.
