Renovation – Are PSL Beams Equivalent to LVL?

If I'm reading this right(and looking at the final picture), the beam itself is sagging. It may have reached an equilibrium point, and simply jacking up an reattaching it will fix it. But you'll still have a bowed beam.

My inclination is, a properly built beam should be able to span that distance and hold the weight without sagging. I have smaller, longer glulams spanning my basement, supporting two stories. But maybe someone who knows a bit more about structural engineering will chime in.

If you want to create one yourself, I would use like 3 2x12's laminated vertically. Boards are much stronger vertically oriented than horizontally. Think floor joists or door/window headers.

This would depend on if you're building a dog house, shed, home or villa.
