    Question Plywood Beam Question

    Does anyone know where I can get information about laminated plywood / floor beams? I was looking at a beam/girder supporting the floor joists that was built from a number of osb strips (.75" x 12") glued and nailed together forming a solid beam about 8"x12"x the length of the house.

    Sounds like glulam (?) - engineered beams. Usually speced by architect. I see them often. Search Glulam or Gluelam - not sure of spelling. Probably stronger than natural lumber.

    An LVL? (Laminated Veneer Lumber)

    Is it plywood or OSB? The post isn't clear; it seems to indicate both. If it looks like plywood, it's probably LVL. If it is OSB, it could be a "homemade" beam which should definitely be subject to engineering review. Or to confuse things more, it could be a parallam beam which looks vaguely like OSB. Photos are a necessity in these kinds of posts! In any case, an 8" beam would almost have to be smaller beams ganged together as that's not a stock size in my experience.

    We called them paralam or LVL. A Gluelam was for exposed wood, such as a ceiling. The ones I dealt with were all plywood, not OSB.

    I recommend contacting Weyerhauser, I contact thier engineers often and they either have a rep who has surveyed the area and knows either thier beams that have been installed or may know which other manufactures are in the area. My local plant is KC but you can check Weyerhauser for the engineering office nearest you.

    Floor beams are plywood.

    The floor joists are TJI (or similar), the girder is an LVL.
