Dimensional Lumber

Various grades of dimensional, pressure treated and untreated lumber, ranging in both size and species (cedar, pine, spruce, fir and more).

Framing vs. Pressure-Treated Lumber

  • Framing Lumber (Spruce-Pine-Fir or SPF)
    Used primarily for indoor construction, framing lumber is kiln-dried to ensure durability. SPF lumber is a versatile choice for general construction projects.
  • Pressure-Treated Lumber
    Ideal for outdoor use, pressure-treated lumber goes through a chemical treatment process that protects it from moisture, insects, and decay. It’s perfect for projects like decks, fences, and other exterior structures. The lumber is easily identifiable by its brown color, which comes from the treatment process.
