Ripping Lumber Will Likely Change the Grade

  • All softwood lumber used for structural applications in the United States today is produced in accordance with U.S. Department of Commerce Voluntary Product Standard PS 20-05.
  • Grading rules for lumber consider the extent, location and number of various characteristics that determine the quality of piece of lumber.
  • If it appears that ripping lumber is the only alternative, hire a certified lumber grader to re-grade the material.
