I think I got close with just some flux core mig wire, but Tig would be better. It is just a Chevron/wheat twist with 4 pairs instead of 2. I welded a bridge on the alternating twists. If you are careful, you could leave the bridges up like they did, I, however, was not.

I am almost certain that the top one is four sets of two twisted bars: Four bars on the inside, each paired with one on the outside. Then, the inside bars are welded when they touch. You can even see where they aren't welded underneath in the second image. I don't have quite the right tools for it, but I will give it a go sometime soon and report.
