Try doing a google images search.

maybe 'floating stair treads' or floating metal stair treads or brackets?

they could also be something else but used as steps.

they almost look like handles of some sort

Most likely a custom fabrication.

An unsafe custom creation. Done for looks only. In an interior brick walled space as an "arty" filler. Or as wall ornament in a covered entry.

what's the point of commenting if you're not answering the question...........

This is custom metal work so it isn't something that you could buy online. You would need to find a metal shop near you and give them the specifications and they would make the pieces and paint them if you wanted. If you are in a remote area you could give the specs to a company to have them make the pieces and ship them to you. Expect to pay possibly $100 per step. Although the more you want the less they will be a piece. Here's a link to a company that takes orders online. Custom Iron Works

beautiful. Thanks for some practical advice. I know i can't just buy it online, I should have worded my question differently. I just wanted to know what they actual rungs are called and what that other piece behind the rung is called. So I can find those pieces @Main Line Kitchen Design

You can show the picture to the metal place. They will want dimensions,

i know its a custom design....this is why i asked for the names of the individual pieces so I can find them. So my welder can weld them together......

I remembered a similar inquiry not too long ago, so searched for the thread. See now it was your thread!
