Southern Yellow Pine

Pinus taeda, Pinus palustris, Pinus elliottii, and Pinus echinata (a commercial grouping of loblolly, longleaf, slash, and shortleaf pine)

Overview 

Southern Yellow Pine grows in the southeastern United States.

It is a strong, dense softwood with straight to medium grain and high resin content. It holds fasteners well, carries load, and wears hard.

Often used for structural framing, beams and joists, decking, flooring, plywood, and outdoor work (treated) that needs strength.
