Pine, Radiata

Pine, Radiata (Pinus radiata)

Pine, Radiata is an imported softwood

Location

Radiata pine (Pinus radiata), also known as Monterey pine, is planted extensively in the southern hemisphere, mainly in Chile, New Zealand, Australia, and South Africa. Plantationgrown trees may reach a height of 26 to 30 m (80 to 90 ft) in 20 years.

Characteristics

The heartwood from plantation-grown trees is light brown to pinkish brown and is distinct from the paler cream-colored sapwood. Growth rings are primarily wide and distinct. False rings may be common. The texture is moderately even and fine, and the grain is not interlocked. Plantation-grown radiata pine averages about 480 kg/m3 (30 lb/ft3) at 12% moisture content. Its strength is comparable with that of red pine (P. resinosa), although location and growth rate may cause considerable variation in strength properties. The wood air or kiln dries rapidly with little degrade. The wood machines easily although the grain tends to tear around large knots. Radiata pine nails and glues easily, and it takes paint and finishes well. The sapwood is prone to attack by stain fungi and vulnerable to boring insects. However, plantationgrown stock is mostly sapwood, which treats readily with preservatives. The heartwood is rated as durable above ground and is moderately resistant to preservative treatment.

Primary Uses

Radiata pine can be used for the same purposes as are the other pines grown in the United States. These uses include veneer, plywood, pulp, fiberboard, construction, boxes, and millwork.
