Now I'm not modelling anymore and have never built a Helix but since building my fullsize tramway I have come to understanding that obtaining a quote from a profile cutter, be it laser, waterjet or plasma etc is well worth the effort of a phone call or visit to discuss your requirements, the results way cheaper than you would think.

I'd see no problem in having the radial roadbed  profile cut from 1/8" steel sheet, the joints being placed at the location of the paired support columns.  These columns would only need a sawblade curf cut in at a spaced interval to hold the steel plate curves, and a short cross-wise rod keeping the columns put every so often perhaps at 120 degrees?  3mm or 1/8" would provide all the support you need if the length was kept at or under 2ft.
