what is your opinion of installing curtain rail on concrete ceiling? what chances of the screw fall down after many years?

I have sliding door with rail screwed to ceiling. after 3 years, many screws fell. I hate to maintain it.

have you encountered rail installation on plaster wall? you will locate the metal structure and screw onto it? can screw to thick metal? example of my mezzanine floor and one side of wall frame below. can screw to the metal vertical black bars?
