How would you finish this interior?

[Ruff]

Working on finishing the interior of my shop, it's a 30 x 32 w two 10x8 sectional doors.

The two side walls are steel frame on 48" centers. The front and back are 72" centers.

I am thinking about putting some type of steel stud on 16" centers for the side walls and 12" for the front and rear.

The only problem is I am not a framer and there is not a top plate to terminate.

Suggestions?

Couldn't you screw the top plate into the bottom of the truss? Think I would also make the back wall 16" on center since it isn't carrying a load. For drywall, OSB, etc. 16" oc is fine.

You can't really see it in the photo but there is a radius on the eve, so I don't think I could just screw a top plate to it. I may just have to go in between the studs with the "top plate".

The front and rear walls are 72", so trying to make it 16" oc won't work. I was thinking 12" oc to make it simple.

I just need something to screw the sheetrock to instead of having the FB studs 48" and 72" apart.

Everything is going to be a challenge. I want to sheetrock the walls, and put a drop ceiling in.

I had to make the eve height 9.5' so I would not have a problem with the city setbacks. The 8' garage doors are a blessing for two full-sized trucks, but with the tracks and cable pulleys above the door will make the drop ceiling install interesting.

Could you use horizontal purlins across what you have. Either steel or wood?
