Pipes for paving stone job

[Bergo]

Where can one find metal pipes for leveling the stone dust? Size about 30mm and about 3m long?

Biltema has steel pipes with a diameter of 20 and 25 mm. Both in lengths of 2000 mm.

I think it will be easier to give tips if you say where you live. In Gothenburg, for example, Göteborgs handelstål http://www.ghsab.se/

The nearest plumber can bring home steel pipes in 6-meter lengths.
