T slotted (or otherwise) framing non-metallic 3

[Bflo]

I'm in search of non-metallic framing and T slots are the easiest to find in metal form. I looked thru an found an old post here regarding the same thing I'm doing but it's 20 years old so all the links but 1 fail and obviously it's been awhile for new companies to emerge. "I need to build frames and enclosures for test instruments and they must be non electrically conducting, all components. Sizes will vary, 200-2000mm cubed. I know there are products like Bosch and Item aluminium extruded frames and constructor sets. Would there be similar in plastic products? There are plenty of plastic extrusions out there but they are mostly application specific like window frames". It's for a small gantry system.

Yeah, we have multiple and I'm gonna print other things for this project so trying to avoid that if possible.

Instead of a caster, just a block of UHMWPE would allow the rack to slide as easily as a caster will. Secure it with a nylon bolt.

Casters are dominated by abuse loads (i.e. slamming into a curb, dropping of an edge....)

You're unlikely to find fully non metallic.

Plenty of choices for non conductive wheels or treads.
