Douglas fir trees are the second tallest conifers in the world, and the predominant species in Pacific Northwest forests. It is dimensionally stable and universally recognized for its superior strength-to-weight ratio. Its high specific gravity provides excellent nail and plate-holding ability. The species also enjoys a documented superior performance against strong forces resulting from natural phenomena such as winds, storms and earthquakes.
