Species

Red pine

(Pinus resinosa)
Sepcification sheet: Red pine

Red Pine is a slow-growing native tree found mainly in Eastern Canada. In homogeneous stands, often in plantations, or in mixed natural stands in association with White Pine or Jack Pine, it can reach diameters up to 60 cm and heights of 25 m. Since the wood grain is straight and readily treated with preservatives, Red Pine is an excellent species for outdoor applications. It can also be used for structural lumber because of its relatively high strength.

Color

The heartwood’s colour ranges from light brown to reddish brown, whereas the sapwood is yellowish white.

Texture

Red Pine wood is relatively light and moderately hard. The wood grain is straight and tapering is minimal. Compared with the heartwood, the sapwood is relatively wide.

Common applications

The thick rings of the Red Pine’s sapwood means it can be readily treated with preservatives. Red Pine can therefore be used outdoors and in contact with soil, and is suitable for poles, piling, railway ties and balconies. Red pine also has great qualities for appearance applications such as boards, panelling, log houses, exterior woodwork, wooden toys, household articles and garden tools. This tree can also be used for most construction work, but is rarely used as lumber since it is more valuable for making boards and poles. Other applications: finger-joined lumber and glulam.
