How To Make A Stiped-Grate Material So I'm currently making a First Order TIE Fighter and I need help making the TIE's texture on its wings. Specifically this texture...

I'm not sure if I should somehow recreate the geometry of a grated-lines look, or use nodes to make simple bump texture. Can anyone give me a hand with some ideas?
I would do some manual loop cuts with Ctrl+R and then follow the instructions I wrote in this answer here
