Installing conduits and boxes in steel building?

[DJFAB]

How do you guys like to provide mounting surfaces for device outlet boxes and conduits in a typical red iron steel building with gurts at ground level and around 7' and no interior sheeting??
I've used strut and 90's in the past, but I can't help but think I'm missing a faster, cheaper way of providing mounting surfaces for outlets at the 4' height.
I've seen guys use wood to go from the ground up to the 7' gurt-but that wood seems have problems of its own(termites, flammable, really doesn't look all that great.)
Thin gauge galvanized steel framing studs seem too flimsy.

What do you guys like?
Would love to see some pictures of nice installs.
Thanks!

Get a Caddy/Erico catalog. They seem to have mounting solutions for every situation.

I have worked on buildings like this. Strut seems to be a good way to go. If you can weld you could fabricate something. I don’t see any advantage to going with anything lighter that 1-5/8 deep strut for the verticals. Like you said, lightweight steel 2x4s are flimsy. They get rigid with Sheetrock or plywood on them.

Maybe try some hat channel. Much stronger than steel studs but a lot cheaper than strut. Could use Tek screws both to fasten it to the gurts and the box to the hat. Would be quick.

Strut with chicken feet. If there’s a better way I’d like to hear it as well. I think hat channel would be too flimsy and the only way I can think to secure the base is to cut and fold it. Typically the specs on a job like this will call for strut mounting unless it’s a design-build project.

I don't think theres really going to be anything cheaper than strut unless you're doing hundreds of these and the dimensions would all the the same. You also have to look at your labor. If you save $2 on something but it costs you minutes of extra time........

Could a wide hat profile be screwed to the face of the girts? Or would the stickout be a problem? If I had the leadtime and was doing hundreds of these and the supports would all be the same, I might be inclined to explore having a roll form place make me a wide hat profile from 16 or 14ga galvanized, maybe even with starter holes where tek screws would go.

Hmm, I don't know if this is any good but what about square steel tube and simpson structural clips to attach it. I was thinking cost on the strut but forgot about the additional $ in strut nuts and brackets.
