Douglas-fir (Pseudotsuga menziesii) is one of the world’s best-known and most widely used wood species. In British Columbia there are two varieties of Douglas-fir, Coastal and Interior.

Due to its strength, Douglas-fir is primarily used for building and construction. It is one of the finest timbers for heavy structural purposes, including laminated arches and roof trusses. Structurally, it is used in the form of lumber, timbers, pilings and plywood.

Douglas-fir is marketed predominantly as Douglas-fir - Larch in structural grades according to National Lumber Grades Authority (NLGA) rules for dimension lumber. Select Structural, #2 and better and stud grades are the most common. Specialty in-house grades and export grades are also available.
