MC cable in grooves in a metal building

[sparkync]

Can, by code, MC cable be run horizontal in the grooves of the outside metal behind the vertical structural braces?
Thanks

Can mc cable be run inside a metal building in the corrugated grooves of the siding?

So it would be similar to running mc inside under a metal roof.

Am I understanding the question?

Indoors or outdoors?

Pretty sure we're talking indoors sandwiched between the purlins and the siding, in which case I would say it is ok.

Hopefully the op will clarify

It is inside, and yes it would be simular to running under a metal roof. That would be the reason I would question it. The chances of someone attaching anything on the outside would be slim but I guess it would be possible
Thanks

Anything is possible. It's not allowed on roofs because roofers use those screws as big as your thumb and as long as your forearm everywhere.

On the walls I could make a case the MC is safer nestled in the corrugations because it's less likely to get snagged by something going on inside the building which is more likely to cause damage, than someone screwing something to the outside.

Possible but not prohibited to be installed in that location.

You could use bat-wings or similar to keep the cables against the beams and away from the outer skin.

As far as I know, yes you can run cables above the red iron in-between the robinson deck as long as nothing protrudes into that space. Per code, I believe you have to be 1.25 to 1.5 inch away from said object that penetrates the space!

Siding is much less likely to be replaced on a metal building. Roofs seem to have a lifespan of 25-30 years then often foam insulation is added with really long screws

What's the interior finish going to be if it's going to be open I see no issue if it's closed maybe this isn't the best location. If a pole building with wood framing remember you need to be 1 1/4 away from the finish and if they are just sideways 2by6 you won't have that apart from the 8by8 posts sections.

Thanks for the replies. Sorry I got tied up, and wasn't able to respond sooner. Again, the cables would be going "behind" the 2x2 steel support beams, and in the "grooves" of the siding behind the beams.
If done this way, it would make a tremendous difference in the amount of mc cable used, since the height of the walls are probably at least 10 or 12 feet before the cable can be run horizontal to the next "drop down", to an outlet.
Hope this clarifies it a little more. Mainly just looking for a "Code reference", if possible.
Thanks
