Oregon-Pine

The Northamerican Oregon-Pine (Pseudotsuga menziesii) is one of the most wide spread timbers which has been used for over 100 years in USA. Strong stems allow a production of flawless sawn timber of much larger measurements than is possible with the technically similar spruce and larch. It´s natural environment is the Northamerican westcoast from British Colombia to California.

The stem is straight and round with a diametre of 0,9- 1,5 m with 20 m of stem-length being knot-free. It is a porefree wood, whereby older trees have a considerable share of particularly fine annual timber, which with annual ring widths of approx 1,0 mm and a correspondingly narrow late-timber zone results in a light coloured, also known as yellow-fir, heart wood.

With common annual ring widths of 1-3 mm Oregon-pine is one of the hardest conifers and has therefore excellent strength properties.

Weight of sawn timber

(air-seasoned): ≈700 kg/m2
(oven dried): ≈0,50 g/cm2

Compression strength

(air-seasoned): ≈68 N/mm2

Bending strength

(air-seasoned): ≈88 N/mm2

The high load-bearing capacity of the wood as well as the possibility to produce flawless rift wood, emphasizes, also with Oregon-Pine, it´s suitability for stage floors. Also with Oregon-Pine, wholes originating from drilling and screws do not close again.
