T slotted (or otherwise) framing non-metallic 2

[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.

Must each individual component be non-conductive, or just the entire assembly?

If it's not available through Grainger or McMasterCarr you may be in for some difficulty. I'd look at those places first. You'd mainly be looking for pultruded fiberglass reinforced channels or struts.

Hoping to do the whole thing non metallic i.e. glass filled nylon screws/nuts, etc.

Looks like McMaster has a wood and polypropylene composite rail that says it's non-conductive. They also have 2 plastic corner brackets. It doesn't look like there are any non-conductive fasters though, but that might be easier to source another way.

How small is small?

Unistrut has FRP shapes. Not sure about fasteners.

There are many manufacturers of FRP structural shapes.

By way of example: https://nationalgrating.com/

They also have FRP threaded rod and nuts.
