Radiata pine originated on the West Coast
of North America and has since been planted widely in the world's south
temperate zone. Large areas of plantation is grown
in South Africa, Chile, New
Zealand and Australia. The bulk of the
material on the Australian market is sourced out of New Zealand.
The species has been very successfully developed given its ease of
propagation, rapid growth, adaptability to a wide range of soil conditions
and its structural properties. The supply volume of this species is growing
rapidly with New Zealand
and Australia
forecasting approximately doubling of available volumes within the next 10
- 15 years.

yellow-brown. Sapwood is wide and not always readily distinguishable from
the heart wood. The texture is fine but uneven. Grain is usually straight
except for a central core of approximately 100mm in diameter which has a
pronounced spirality.
Shrinkage about 3 % radial
and 4.5% tangential. The material is easy to work and nails satisfactorily.
The wide sapwood band is readily treated with preservative chemicals so
lends itself to a number of extrernal application as a treated product. Very commonly
available in both untreated and treated timber in a wide range of sizes and
profiles.
