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.
Treated radiata pine is suitable for structural uses, decking, fencing, exterior cladding, window sashes, pergolas, landscaping, shingles, barge boards & exterior trim.
Interior uses for untreated timber include furniture, mouldings, trim, & panelling. Panel products, such as plywood, MDF and laminated veneer lumber, are also available from radiata pine resources.
Radiata pine is easily treated and Napier Pine can supply it with appropriate durability in any of the Hazard Classes from H1 to H6.
