Pitch Pine

Commercial names:

Other names:

Gulf coast pitch pine, longleaf pitch pine (UK); longleaf yellow pine, longleaf (USA); southern yellow pine, southern pine.

Distribution:

Southern USA.

General description:

The heartwood is orange to reddish-brown in colour and resinous. The growth rings are clearly marked by the contrast between the light early wood and darker, denser latewood. It has a coarse texture, especially in rapid grown timber. The weight varies between 660 and 690 kg/m3 (41-43  1b/ft3) and the specific gravity is .67.

Mechanical properties:

This pitch pine has identical strength properties to Douglas fir. It is not for steam bending due to its resin content.

Seasoning:

This timber dries well with little degrade and has a small movement in service.

Working properties:

This particular timber has a moderate resistance to cutting edges with machine and hand tools. It also finishes clearly. The resin can be a problem in clogging cutters and saw teeth. Saws with long pitch reduce this effect. The timber holds nails and screws firmly and it can be glued without difficulty. Paint and other finishing treatments are fairly satisfactory.

Durability:

It is moderately durable and it is susceptible to insect damage. The heartwood is resistant to preservation treatment, but the sapwood is permeable.

Uses:

It can be used for heavy construction work, lorry and railway wagons, shipbuilding, spars, masts, exterior finish, flooring, dock work, decking, etc. Lower density grades are used for joinery, light construction, boxes, crates, pallets, etc. A large percentage of the resin of the world is produced from these species.
