Douglas Fir Dimensional Lumber

The strongest of British Columbia’s family of softwoods, Douglas fir (pseudotsuga Menziesii) is characterized by strength, stiffness and durability. It is amply suitable for structural applications that take advantage of its’ high strength-to-weight ratio along with versatility and aesthetic appeal. Truly, it is the best species for heavy structural applications just as joists, headers, rafters and glue-laminated timber construction. Coastal and Interior Douglas fir is known for its rich pink heartwood and creamy white sapwood adding visual appeal to the overall strength of the species.

The desirable physical properties and wide range of available sizes make Douglas fir the material of choice for a broad spectrum of end uses—ranging from post and beam & heavy timber construction to glue-laminated timbers; from porch and gazebo projects to the heaviest of bridge components; from piling and shoring applications and beyond, the structural performance and inherent natural beauty of Douglas fir make it a smart choice for many applications.
