Re: [CAD_CAM_EDM_DRO] Cold rolled steel, flats or square for use as rails.

Proper lubrication with way oil (such as Mobil Vactra #2) applied
either manually or via a Bijur-style manual or automatic oiler
directly to the bearing surfaces should prevent rusting. Equipment
like this really should be in a climate-controlled environment
anyways.
