What would you call this metal track?

I need a longer length of the track in the picture, but I have no idea what’s it’s called in the trade nor what to search for.

could anyone advise of it’s name, where I might be able to get some? It’s for a bike carrier, my MTB is XL and is a bit dodgy during travel.

Thanks.

It's just slotted or perforated angle.
