Drop ceiling with Steel Floor Joists

I've been working on finishing my basement and I've been planning on putting a drop ceiling in. The walls are in place and finished, and I'm ready to move onto my ceiling but I'm not sure how to begin. The floor joists in my house are steel, not wood and I am not sure what the best way to attach the hangers for the ceiling to the steel floor joists would be.

Here is a picture of the joists in my basement:

Thank you to anyone who can provide me some assistance on figuring this one out.

Is the ceiling above the joists wood?

Just plan your wire drop pattern and drill sheet metal screws into the side of the joist, leaving enough head space to wrap your wire. That is 14 gauge steel, so it is tough.

They make self taping eye screws made for attaching wires into steel. Go to a supplier that sells suspended ceiling materials and they will have what you need.
They will look something like this: Screws
How do you drive them you ask?: Driver

Don't make it harder than you have to. Looks like those floor joists already have various cut-outs to allow utilities access thru. Just use those. Loop the wire over / thru the cut-out, give it several twists with a pair of pliers, then pull down on the long end to take out the slack & hang straight down. Then when you are putting up your main runners adjust the height at the runner level. Even if they are not perfectly spaced / centered you will be OK. Remember it is just a drop ceiling & most of us use too many hanging wires anyway given the load. Good Luck.
