Radiata pine is native to California but is now the most widely planted pine species in the world. Australia has substantial plantations of this high demand and fast-growing tree, to cater to the many that choose to buy building supplies in this timber.
Properties of Radiata Pine
A low-to-medium density softwood, the grain tends to be of fine texture and straight, but characterised by knots, which contribute to Radiata Pine’s charm and natural appearance.
The colour ranges from light brown to yellow at the core, and paler yellow to white in the outer sapwood. The inner 100mm core can be prone to twisting and effects from moisture. This timber is often characterised by wide growth rings and is not naturally resistant.
With its open grain, Radiata Pine is easily treatable with water, solvent and/or oil borne preservatives all the way to an H6(highest) hazard level, to make it resistant to moulds, fungus, insects and moisture.
Appropriately treated, beams, boards, posts, piles and sleepers are used for external structures like decks and fencing. Other uses, including internal, are:
