  Hello all, Working on a 24 x 36 off grid cabin.  Using pole barn construction.  I need 6 non load bearing beams to span the 24' width.  These are for "looks only", as useless as that sounds.  Any ideas on how to buy or construct a beam 6x6 or 6x8 at this length?  I thought of the engineered beams of 2x4's and osb down a dado groove in the 2 by's.  I can cover all sides with thin lightweight cedar.  Appreciate any ideas.

  Why not just make a box out of the cedar?
  Screw a 2x4 into the ceiling. Tack the cedar around it.

  Thanks for the reply.  I didn't explain effectively.  The ceiling inside is 10'.  I'd like to place the beams at 8' to give an appearance of lower ceiling.

  A drawing would help. Sounds like you are making a soffit along the inside of the wall 2' down from the ceiling. I usually see these made from 2x4s, sometimes plywood. Don't see what you mean about the dado. Since it's non-structural it's really about what is most convenient and easy for you. Creeky's idea of just making a cedar box could have the advantage that you could make the boxes at home, bring them on site and assemble them, minimizing the time spent on site. 
  Consider running a string of LED lights on top of the soffit for soft lighting.
  Or, did you mean running box beams as faux ceiling beams every 4-6 feet, and lowering the ceiling, leaving a 2' attic?
  drawing would help.

  Bingo.  Box beams dropped 2ft from ceiling to give appearance of a lower ceiling.  Only place to attach is around the perimeter of the wall 8ft up as I want the free span look.  The prefab floor trusses can be bought using a 2 x 4 for the base and top (where decking is nailed) with osb vertically down the middle of the 2x4's in a dado groove.  An "I" beam.  Problem is they are made for structural support and are 14" Tall or more.  A 6" metal I beam would work, I just don't want the weight to deal with.  May have to can the idea.  I do appreciate the response.

  The larger question is how is the roof constructed? Is it trusses, rafters suspended from a structural ridge or stick framed and in need of ties?
