Just curious how others have done this…

I have been asked to wire an aircraft hangar with basic receptacles and LED lights. What is the “best” method of attaching a 4x4 metal box directly to an i-beam? I’m looking at beam clamps to the beam with small shallow unistrut pieces to mount the box.

What have others used that looks good and holds over time? I can’t mount straight to the beam - engineer specifies no mounting holes in the beams. No reason to re-invent to wheel.
 
If money is not a real issue, I like the B-Line column support clamps as that will let me tuck the box behind the beam flanges if the beam is deep enough. The B-613A works with the shallow strut.
Have always wanted to try a magnetic mount, but never have
 
If you buy the correct self tapping screws. You can buy them with a drill tip with 24-28 threads /"inch. They claim you cand drive them in 1/2" steel.

They work great. I don't think I ever used them in 1/2" but I have done 1/4" and probably 3/8" plenty of time and they work great. ITW Build dex is one brand. Have to buy the fine thread screws


WHOOPs: just re read your post about no holes in the beams so that is out.

That seems unreasonably cautious. Have you asked about an exception, for a limited mounting pattern for #10 bolts & nuts?

Powder-activated fasteners might also be an option -- they completely fill the hole they make with a piece of hard steel and almost a metallurgical bond, as tight as hot riveting.

I suppose you could mount the box to strut, but it isn’t necessary. You would probably need something like this to support the conduit.
