Metal Strut Framing

[qorghdud]

Hi everyone - I'm thinking about building the frame for the impact screen using metal strut. I've seen some posts/videos on it and I think it'll work well for my space with the tray ceiling. I would be making a rectangle using brackets, but still concerned if I can drill screws into the tray ceiling there (picture attached). I'm not an expert, but I think similar to studs on the walls, ceilings have joists? Using the stud finder, the entire corner is catching which makes me think there's some sort of metal corner piece that's wrapped around something (possibly joist?), but the concern is that I'm not sure if the ceiling will be strong enough to hold the weight of the strut and impact screen. Also, the studs don't align on the side walls and was going to use those wall anchors for the side struts. If anyone has any suggestions would be greatly appreciated! Thank you!

At that price, I might just consider designing and building from lumber. Much easier to work with and easier to adjust if things don't work out to plan. No real way to tell from here what may be hidden inside the tray. Could just be decorative or could be functional. Also, whether you can suspend anything from it really depends on how it was built. I would anchor to the ceiling where possible and structure from the sides. My 2 cents.

The studs and joists on my sidewalls and ceiling didn't match up for mounting the strut, so I screwed 4x8 sheets of 1/2 OSB into the studs and joists, and then screwed the strut to the OSB 12" off the back wall.
