Any post frame builders/ structural engineers?

My shop is 36 x 45, posts are 9' centers, trusses are 9' on center with a wall down the middle separating the two sides. I'm wanting to put a steel ceiling on the side I heat. I'm thinking of putting joist hangers every two feet between the trusses with 2 x 6 joists, hang the steel and put fiberglass batting insulation on top. I want to make sure the trusses can handle this. Any input greatly appreciated.

Thanks, Nate

That sounds similar the method Morton Buildings uses in their buildings. The only difference is they use 2x4's on end (nails though the 4") nailed to the bottom of the trusses.

Is the truss spacing really on 9' center or is that a typo?

No typo, 9 foot centers. 36 foot trusses every 9 feet. The trusses are 2 x 6, the gussets are 2 x 4, all metal plate connected. Menards building built in 1976. I went and bought the materials Sunday- joist hangers and 10 foot 2 x 6's. What do you think?
