Heartwood is reddish brown, sapwood is yellowish white.
Large resin canals, numerous and evenly distributed, mostly solitary ; earlywood to latewood transition abrupt, color contrast high; tracheid diameter medium-large.
Overall, Slash Pine works fairly well with most tools, though the resin can gum up tools and clog sandpaper. Slash Pine glues and finishes well.
The heartwood is rated as moderately resistant to decay.
Straight grained with a fine to medium texture.
Slash pine has been reported to cause allergic skin reactions and/or asthma in some people.
Should be widely available as construction lumber for a modest price.
This wood species is not listed in the CITES Appendices, and is reported by the IUCN as being a species of least concern.
Slash Pine is considered to be in the group of southern yellow pines, and shares many characteristics with other species of this group (Longleaf, Shortleaf, and Loblolly Pine) such as being: hard, dense, and possessing an excellent strength-to-weight ratio.
