Wood Species - Pine
SOUTHERN YELLOW PINE
Color: Heartwood varies from light yellow/orange to reddish brown or
yellowish brown; sapwood is light tan to yellowish white.
Grain: Closed, with high figuring; patterns range from clear to knotty.
Variations within species and grades: Longleaf pine (P. palustris), shortleaf
pine (P. echinata), loblolly pine (P. taeda), slash pine (P. elliottii). All
have many of the same characteristics as Douglas fir. Old-growth lumber in these
varieties has substantially higher density and is more stable than second-growth
Hardness (Janka): Loblolly and shortleaf 690, 47% softer than Northern
red oak; longleaf 870, 33% softer than N. red oak.
Dimensional Stability: Above average (change coefficient .00265; 28%
more stable than red oak).
Durability: Soft, fairly durable, although not as resistant to scuffs,
dents and abrasions as the hardwoods. Often used for flooring, but may not be
suitable for all applications due to its softness.
Sawing/Machining: Good machining qualities.
Sanding: Resin in wood tends to clogs abrasives; frequent sandpaper changes
Nailing: Good holding ability and resistance to splitting.
Finishing: A durable finish can help minimize wear.
Comments: Generally manufactured for flooring with no end-match; sometimes
flooring is “distressed” to create an antique look.
