Electrical wholesalers for galvanised steel conduit and fittings?

No, modern conduit is (usually) welded and that will give up and crimp
on you in this application. US "black iron pipe" (wonderful stuff) is
intended for pressure so it's seamless drawn, thicker walled and
useful for mechanical jobs. Shame you can't get it, and it's getting
hard to find '60s vintage thick-wall conduit too (industrial scrappy).

I'd regard both of these are far too thin and far too light for this
job. You end up with a stand that jumps about when you lean on it (the
main reason why I prefer a "bolt to my workbench" bike stand).
