Aluminum Composite Question

I need to butt 2 pieces on 6MM composite together with a frame around the outside. The sign is 2 sided and circular in shape and 8' diameter, 2 pieces of 4'x8'
My question is how can I keep the center together so the wind does not affect it? Is there a glue or some sort of biscut type joint that works, or just a couple pieces of flat steel bolted on each side?

A round 8' diameter circle of 6mm.......... ??

  • Hmmmm, how is this gonna be hung or attached ??
  • Are you married to 6mm composite ??
  • Have you entertained a more suitable substrate to meet your needs ??
  • You do realize that your diameter will need to be more like 95" and not 96" ??
