Dimensional lumber or Framing lumber is ideal for a wide range of structural applications including framing of houses, garages, sheds and commercial construction, as well of non-structural applications. Certain size (studs) boards are available Kiln-Dried to ensure limited shrinkage and movement when framing a structure.
Dimension lumber grading rules limit natural characteristics and manufacturing imperfections that affect the strength and utility of the piece
Structural lumber (including dimension lumber) is visually and/or mechanically (MSR) graded for its strength and physical working properties (appearance is secondary, unless specified)
The wood is very stiff and strong for its weight, and is also among the hardest and heaviest softwoods commercially available in North America
Doug-fir is often installed in its "green" or unseasoned state, and allowed to air dry during construction
Brand/grade may vary based on availability and stocking location
