Expanded Metal Sheet

I am looking for a sheet of expanded metal, but not in the typical diamond shape pattern you usually see. Something in a honeycomb, hexagonal, octagonal etc shape This is for a headache rack being fabricated for one of our new trucks. I see different styles of expanded metal on some of the mass produced headache racks, but not having much luck finding just a flat sheet of it to purchase. is anyone familiar with what we are looking for? Any input on this would be greatly appreciated. I will attempt to attach a picture of something similar to what I am looking for
