Radiata Pine has a number of structural uses including decking, fencing, exterior cladding, window sashes, pergolas, landscaping, shingles, barge boards and exterior trim.Untreated, it can be used for furniture, mouldings, trim and panelling.Panel products, such as plywood, MDF and laminated veneer lumber, are also available from radiata pine resources.
Radiata pine is grown commercially in New Zealand as an exotic species from the Monterey peninsular in California. The majority of plantation forests are Forest Stewardship Council certified.
The Resource Management Act 1991 places several requirements on forest growers, including the need to consider employment, social, cultural and environmental impacts. This results in a level of environmental responsibility that does not exist in other countries.
In addition, 80 percent of plantation forest owners have adopted the New Zealand Forest Owners’ Environmental Code of Practice for Plantation Forestry (2007). The code of practice covers areas including the protection of waterways, endangered species, historical sites, sediment control and the management of fuel, oil and wastes.
Afforestation with Radiata pine rehabilitates previously farmed soils by reducing compaction caused by stock, with soil condition improving with subsequent rotations.

Radiata pine is a versatile and readily available timber, suitable for a wide variety of end-use applications.
Low level treatment such as boron is recommended to future-proof against insect attack in areas completely protected from moisture, such as furniture and the framing of internal walls of buildings. The timber is easily treated for all Hazard Class applications.
Radiata pine is easily processed, dried and treated, and will take staining and coating. It is used in conjunction with a range of structural adhesives.
Tests have confirmed that radiata pine machines well for most applications and compares favourably with a variety of other internationally traded timbers.
The heartwood of radiata pine is an even light brown to chestnut brown in colour, the sapwood is creamy white.
Radiata pine heartwood is an even, light brown to chestnut brown colour, the sapwood is creamy white. Resin canals are present as fine brown lines in the latewood part of the growth rings, especially on radial surfaces, and these can be a handy means of identification. Texture is fine but uneven.
The contrast in colour and texture between early and latewood bands (growth rings) in flat-sawn timber is relatively moderate compared with other pines and conifer species. The veneer has a moderate-to-high lustre. Common features in most Pinus species, including radiata pine, are: knots, cone stem holes and pine-needle flecks.
Radiata pine is a versatile and readily available timber, suitable for a wide variety of end-use applications. It produces wood that is very acceptable to the construction industry. The bark is rich in tannins and suitable for use in the manufacture of adhesives; it also contains some wax, which may have possible use in water repellents. It is suitable for framing, industrial uses, posts, cladding, decking, interior finishes and trims, and everyday furniture.
Radiata does not begin to form heartwood until it is about 15 years old and forms it at the rate of one ring every two years. Most of the wood, therefore, is easy-to-dry and easy-to-treat sapwood. This is an advantage over many Northern Hemisphere conifers, which are largely heartwood.
