Diamond Star Top Rail Options

Is there anyway to change the top rail and caps from resin to metal on a diamond star 18x33x54? I have a lot of caps broken after one year of use. Or maybe change the type of caps used to something stronger?

Thank you for your time

Oh yeah, the rail is 11"

We have steel replacements for the top rails but not the top caps.
