Ok after spending all day running around plumbing and electrical stores I found a solution and wanted to post it up here incase someone else has the problem.
From a plumbing store I found 12' threaded rods. I found I-beam clips at a drywall supply store, and I got 10' metal beams with bolt holes from an electrical store.
Basically I'm going to attach the Ibeam clips to the threaded rods and hang them. The bottom of the rods will be inserted into the metal beams and attached with nuts.
Once you get this far and put tension on the rods you can stick an extra metal beam up there to slide the rods into position directly over the table. After it's in position loosen or tighten the bolts to get it level.
Then I got threaded hooks from home depot. These are put through the metal beam and attached with a wash we and nut.
Now I have a 10' beam hanging directly over the tables just a couple feet above the tiles. Punch holes through the tiles as needed and attach the chains to the hooks.
It's a real pain... Took me like an hour to do just one. They are supported great though, and I don't have to worry about them falling.
