One thing not mentioned by others is the need for bracing (in house construction we call it bridging) between the beams- any kind of beam. As the load increases and the beam begins to deflect downward, it also begins to rotate along the axis. If the rotation is controlled, the vertical sag is also lessened. It is critical that the ends of the beams be blocked from rotating- like the rim joist on a house. Intermediate blocking is aslo beneficial.
