Use steel for the structural elements, cap with composite material
to match your deck. Works quite well.

Dan,

That sounds like a good idea. Are you talking about some kind of custom made
steel railing that needs to be welded, or are there pre-made railings that
you can buy at lumber yards that work well for this? How do you cap them --
do you mean just adding a composite board on top of the top rail? Do you
know of any photos online that show a steel railing capped with the
composite material? That would be really helpful to see!
