Pine
(Southern Yellow) Species Information
Top portion is finished with water-base urethane; bottom with
oil-modified polyurethane.
Appearance
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
material.
Properties
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.
Workability
Sawing/Machining: Good machining qualities.
Sanding: Resin in wood tends to clogs abrasives; frequent sandpaper
changes are required.
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.
