Kail – Pine

Radiata pine is native to the central coast of California but is widely planted in Australia and New Zealand. It makes up 28% of Tasmania’s timber plantations and is popular in all types of construction and decorative uses. These include framing, lining, glue laminated beams, veneer and plywood. It can be used for many exposed structural and non-structural applications if it is treated with the right preservatives.

The texture of radiata pine is fine, but uneven, and knots are common. The timber is fairly soft and has a low density, often with very wide annual growth rings. The sapwood is white to pale yellow, but often indistinguishable from the heartwood, which is light brown to yellow. The grain is usually straight, apart from a central core of 100mm, which can twist if the moisture content of the timber changes.

Radiata pine is easy to work, apart from the knots, and it readily accepts preservatives. Timber that is high in resin can be hard to glue and the resin may mar painted and stained exteriors. It does not cause staining of alkaloid surfaces such as fibre-cement and concrete.

Radiata pine is not resistant to termites. It can be preservative treated to increase its durability.
