Lumber You Can Trust

As a family-owned sawmill in Lyons, Oregon, we take pride in manufacturing quality Douglas Fir lumber right here in the USA. Our mill produces MSR (machine stress rated) lumber for truss manufacturers and lam stock for glulam beam fabricators. We manufacture lumber in sizes 2x4 through 2x10, in lengths from 8 feet to 20 feet. Each board is tested with our state of the art Metriguard system to ensure consistent density, stiffness, and strength—giving builders confidence in every piece of lumber we produce.

Benefits Of Our Lumber

Durability and Stability

Douglas Fir is resistant to mold, insect damage, warping, and shrinking in a wide variety of weather conditions due to the high density of the wood, increasing the longevity of projects.

Easy To Work With

Douglas Fir is easily shaped, cut, and joined, making it perfect for complex projects. It is also very aesthetically appealing due to its uniform, straight grain pattern and warm color tones. If you want to add paint or stains to the wood, it applies easily, allowing for increased customization.

Versatility

Douglas Fir can be used for a variety of purposes, both residential and heavy duty, such as framing, flooring, furniture, etc. making it the ideal wood for every project under the sun.

Great Weight-to-Strength Ratio

Douglas Fir is one of the strongest lumbers within the softwood category, making it ideal for uses typically reserved for hardwood lumber. Due to its lighter weight, it is easier to work with.
