Building a Storage Loft: Joist Hangers for Concrete and Drywall

[samfsu]

Hello all. I was hoping someone could help me. I am building a storage loft in my garage. The issue that one side is drywall and metal studs. I was thinking that I would attach joist hangers to the concrete wall, then another set into the drywall wall but I wanted to know if the joist hangers into the metal studs would work well? So basically two joist hangers about 3 feet apart with a 20ft joist in each set, one in the concrete wall and the other in the drywall wall.

OK. Since the area of your house in this case(garage) in not considered "occupied" you do have some wiggle-room with regards to safety of construction variation.
Although some homeowner polices/municipal codes do not allow this.

In any event, what you described is problematic enough to warrent a professional assessing, on-site, what should be done.

I only say this because one of my brothers is a professional contractor, and will not advise on remodeling without on-site inspection. Should only cost about $100 or free.
Just some thoughts for you and best wishes on your future storage loft!

What are you going to put up there - styrofoam.

Metal stud walls are not bearing walls.
Use a vertical 4x4 for support at the drywall side ansd also support for lateral movement as a minimum. You don't want all that stuff up ther coming down on someones head.

Thanks for the suggestions. I am strongly considering having a contractor come up to either build it or assist. Last thing I need is to have this come down on my cars.

I did think about the 4x4 and will be reinforcing the drywall side with a ledger that i reinforce with 4x4s under and then 4x4s at the midway point spanning the garage.

Any other thoughts or suggestions?
