I mean that is an option. It is tough to see with the foam in the way but you may be able to support the fan without going the whole length across. Lot of variables come into play. A large fan may need more support.
This is what the ceiling looked like before I had it sprayed.
One option, that I’m not really fond of but may possibly work is getting rid of the foam over these little support brackets so it gives me enough room to shove a 2 x 6 and lay it on top across two of them. The thing I’m worried about is these brackets are held in with a total of four self tapping screws. I’m sure all the foam adds to the strength but how much it adds I am not sure.
The other option is get a small H beam or I-beam and run it across the garage from left to right. I know the frame on the left-hand side will hold 200 pounds. I currently have a unit strut with a little winch to pick things up every now and then. When I picked up a compressor, I did not hear any creeks or stress from the metal. The other end of the I-beam will obviously have a support pole going down to ground level.
This seems like a lot of work to do for a fan installation, but I’m not sure what are my other options are.
The second picture that shows the foam panels on the ceiling you can get a clear view of the area I would put the beam on. I ended up taking these panels down and had everything foamed.
