I'm a sailmaker, and we call it caravan annex track! Over here in
Australia, you can get an extruded PVC version of it, that bends around
compound curves really nicely, and with properly spaced fastenings, is
very strong.

I've used both - the extruded PVC does go around curves nicely, but a really
strong wind or wave can pop out a bolt rope because the extrusion isn't
strong as the aluminum. If you go with aluminum, find out the alloy; should
be 6000 series.
