Can I use a 6×6 as a deck beam? First, the IRC only allows certain dimensional lumber to be used for deck beams. In the past, 4x4s and 6×6 lumber could serve as beams, that is no longer the case. You must use 2x material bolted together to create a deck beam, or use metal or engineered lumber.

If you assume a conservative 1400psi allowable bending stress, a single 6×6 with 12′ span can support about 2000 lbs. So your double 6×6 can support at least 4000 lbs (possibly more if you do a good job bonding the two members together so that there’s no slip between the faces).
