Hanging outdoor panels

I just finished making 6 panels for my son-in-law, and each is 15"x45". He plans to hang them outside on his patio, and wants to chain them from rings at the top and the bottom on each panel. I worry that the wind could cause them to "torque" and break the glass, and would prefer he just hang them from the top to allow them to move freely. What is the proper way to hang outdoor panels that have zinc came framing?

Answer

I honestly don't know the proper way to hang outside panels, but I do know hanging freely would not be the way to do it. They would fly around in the wind and break pretty fast.

Your son-in-law's idea is a better one, but I'd put them in wooden frames first. The wooden frames should prevent any torquing.

Perhaps someone reading this has had experience hanging panels outside and can tell us wht they did. If so, the answer will be in the comments section below.
