RADIATA (Pinus Radiata)

Radiata (Pinus Radiata)

Radiata Pine is a versatile and readily available timber, which is suitable for a wide variety of end use applications and products, including mouldings, finishings, weatherboards and fascia.

Mechanical Properties At 12 percent moisture content, the density of radiata pine varies from 560 kg/m3 from low-altitude growth sites from the Waikato northwards, to 460 kg/m3 in timber supplied from Otago and Southland. The average density figure for the whole country is 500 kg/m3.

Most of the density variation is related to the average temperature during the growing season: the cooler the site, the lower will be the wood density, hence the decrease with altitude and latitude.
