Best Way To Attach Cameras & Conduit To Structural Steel?

I've got a job that involves installing cameras inside and outside a typical steel hangar. As illustrated in the attached picture, there are no wood/metal studs or plywood to attach anything to. The walls are just metal siding lined with thick insulation which I rather not tamper with. So, I am left with attaching cameras and PVC conduit right to thick structural beams/columns.

Anybody have any suggestions on the most efficient & cost effective way to do this?

Steel Hangar Construction


There are a few ways to do this. Electricians have the same problems hanging conduit, so in many cases, your local electrical distributor will have clips or brackets that will work great, like this conduit pipe clamp that costs a few bucks each:

Also, the Spinning Camera Mount is designed for this exact application.

'Truss/Joist Brackets' are sometimes available as options for standard camera mounts that are generally u-bolts or carriage bolts that mechanically fasten to steel without need to cut or thread through them. However, these are generally for webbed joists, not solid steel girders.

From experience: make sure any metal-to-metal mechanical fastener is tightly installed, and use a thread locker during install to keep nuts from vibrating loose over time.

Especially at an airport, where wind/engine vibration is pretty constant, any nuts can back off in mere weeks. Make it tight, keep it tight, and ensure your camera doesn't crash down into someone's multi-million dollar airplane.

I take it these connectors have to be drilled into the steel members?

No, not drilling is the key to their appeal. I marked up the clamp image so it may make more sense:

Ah, I see. The connector clamps down on the flange of the steel member. Very nice.

I always used Caddy beam clamps and conduit hangers. They've got a lot of varieties for various beam types. They're simply clamped to the steel and you hang conduit, J-hooks, cameras, etc. from there. You may need to adapt whatever it is you're mounting to whatever thread type the clamp has (usually 3/8 or 1/4-20), but that's just a matter of getting the right screws.

I love the options on those clamps Ethan! Now I've got a good idea of what to look for.

Thanks so much Brian & Ethan, very helpful.

Caddy is a manufacturer of fasteners designed for fastening conduit, boxes etc. to steel I-beams. There are others that do the same. Where you are running conduit at 90 degreres to the I-Beams, you may want to consider strut as the support mechanism.

There are other optiions based on your layout of the Hanger. Check the cost of each and always check with the AHJ - authority having jurisdiction for acceptable options
