I'm trying to find the manufacturer of 'heavy duty' round plastic conduit-
ideally about 20 mm in diameter.

As far as I can tell, there is no real standard for this stuff- other that
the outside diameter- and I've seen stuff with very thin walls, some
thickish, but only one really thick type. This makes the stuff quite
rigid-
which is what I need for this application. It is 'pure white' like the
more
common stuff and the walls must be almost 3mm thick.

I know the stuff exists (I had a bit in my hand the other day but
foolishly
didn't follow it up at the time).

Applicaiton is DIY but not 'normal' electrics- the normal stuff from the
DIY
sheds and even the local electrical factor isn't rigid enough.

Anyone know the product?

Ever thought about using white plastic plumbing pipe? It's cheaper than
conduit, and it seems to match the sizes quite generally.
