- New Zealand radiata pine. The following description of the physical characteristics is intended to provide preliminary technical advice for current and intended users.
- Density of Radiata pine. Medium density ensures versatility. Average tree density (oven dry weight-/green volume) is lower near the pith and higher near the bark.
- Strength of Radiata pine. The Timber compares favourably with other species in bending strength, bending stiffness and fastening.
- Permeability of Radiata pine. Radiata Pine forms heartwood at about 15 years and progresses slowly. At 30 years about 20% of the stem is heartwood.
- Sapstain. Although sapstain fungi will colonise and discolour untreated wood. Modern treatments can effectively prevent sapstain.
- Shrinkage and Stability. Radiata Pine has good stability and low to moderate shrinkage. Radiata Pine compares well with most other softwoods. ...
- Colour of Radiata Pine. Radiata has a light coloured sapwood with slightly darker heartwood. Exposure to the sun leads to a yellowing of both heartwood and sapwood.
- Mechanical Properties. The mechanical properties of sawn lumber are closely related to knot size and density. ...
- To find out more about:
- Sapwood: pale yellow.
- Heartwood: reddish brown, varying to shades of yellow.
- Texture: non-uniform, consisting of alternating bands of earlywood and latewood; straight grain; knots usually present in constructional timber grades.

Is radiata pine a softwood or hardwood tree?
Radiata pine is a softwood tree, which means the wood does not have pores and in comparison to hardwoods has long fibres (tracheids). The name softwood is confusing because radiata pine is harder (denser) than many hardwoods such as balsa and poplars. Watch out a lot more about it. Just so, what is the hardness of radiata pine?

What are the identifying features of radiata pine?
Identifying features Radiata pine has a long straight cylindrical trunk. Its bark is dark reddish-brown, thick and deeply furrowed,with scaly ridges.
What are the benefits of radiata pine?
Compared with many other pine species, radiata pine is: • fast-growing and able to produce large logs in under 30 years; • flexible in growth habit, so can take advantage of a range of climates; • a nutrient-demanding species; • a versatile (although not exceptional) general-purpose timber.
Is radiata pine water resistant?
Look for exterior AC grade radiata pine plywood for outdoor use in construction projects, soffits, fences, and more. Since this type of treated radiata pine plywood resists moisture, it is suitable for applications such as outbuildings, lining commercial boxcars and trucks, lining commercial refrigerators, and more.

Radiata pine is a softwood tree, which means the wood does not have pores and has long fibres (tracheids) compared to hardwoods. However, the name softwood is confusing because radiata pine is harder (denser) than many hardwoods such as balsa and poplars.
What is the versatility of radiata pine?
OUTSTANDING VERSATILITY Nailing, screwing and sawing of radiata pine wood is carried out in a very simple way, which guarantees easy handling and the realization of more refined finishes. Another of its great qualities is that its texture adheres perfectly any type of dye, paint or varnish.
What can you do with radiata pine?
Radiata pine sawlogs are used for house frames, decking and panelling, fencing and landscaping, flooring, joinery and furniture. Pulpwood is used to make reconstituted timbers such as medium density fibreboard or particleboard and paper products.

Lighter. Radiata Pine is an affordable and light weight option for mass-timber construction.
Is radiata pine good for furniture?
Radiata pine lumber has a wide variety of uses including furniture, cabinets and millwork, as well as for paneling. It is widely used for building and structural applications, including glue-laminated beams and engineered trusses. It can be easily pressure treated and used in exterior environments.

What is the difference between heartwood and radiata pine?
Color/Appearance: Heartwood is light brown, wide sapwood is a paler yellowish white, and is distinct from the heartwood. Radiata Pine lumber is plantation-grown, and generally has very wide growth rings and is knot-free. Grain/Texture: Straight grained with a medium, even texture.
Where is Radiata Pine grown?
Pricing/Availability: Radiata Pine is grown almost exclusively on plantations—most notably in Chile, Australia, and New Zealand. Prices should be moderate for an imported lumber, though most likely more expensive than domestic pines/softwoods.

This species accounts for about 90 percent of the total planted resource. Radiata Pine is originally a native species from California and was introduced to New Zealand in the 1860's as part of a reforestation programme.
Where do knots occur in timber?
Although they occur in trees in all parts of the country they are the most prevalent in some areas, particularly Canterbury. Other than the defects associated with the weaker corewood zone, such as pith and spiral grain, the main defect found in the sawn timber is that of knots and to a lesser degree resin pockets.
What is the density of corewood?
The density of the younger wood is between 350 kg/m³ to 400 kg/m³ that stabilises as the wood reaches maturity to a density of 450 kg/m³ to 610 kg/m³. The corewood, which is usually confined to the innermost five rings, has a very low density, shorter fibers and higher longitudinal shrinkage than the outer wood.
Can radiata pine be dried?
