Hi John, I’m from Denmark too.
Bauhaus actually has chrome 25 x 1.2mm pipe in 2m lengths, can’t find it on their website though.
I used those, not as cheap as I would like, but the rollers run very well on the smooth chrome surface 🙂
Also Sanistaal has “dekorationsrør” 25mm in stainless.
Didn’t manage to find anything really cheap though
