Concealing wires on concrete ceiling
I've been a reader here for years but this is my first post. Trying to get some help figuring this out.
I just moved into a new space and trying to get it all wired up. I want to run a bunch of stuff from a main closet that I'm going to be setting up. Probably like 10-12 ethernet runs, 2-3 hdmi cables, and some cables for security cameras. The space is pretty big 75ft long by 19 wide.
The issue I have is, the ceiling here is concrete, this used to be a warehouse that they turned into lofts. The walls are sheetrock, so its not an issue to run them behind/inside the wall, but for the ceiling, the landlord said absolutely no exposed wires whatsoever and I can't put them in the concrete, so I need some kind of conduit or something. I tried to find wiremold that would hold that many cables but couldn't find anything.
Can anyone give me some suggestion as to what to use for this?
