In den Fabriken wird zunächst Zinn in Form von Barren oder Blechen angeliefert. Die Handwerker schneiden, formen und giessen das Zinn in die gewünschten Formen. Es können verschiedene Techniken Anwendung finden, darunter das Walzen, Gießen oder das Treiben, bei dem das Zinn mit einem Hammer in die gewünschte Form gebracht wird. Diese Techniken erfordern viel Geschick und Präzision, um ein qualitativ hochwertiges Endprodukt zu garantieren.

One of the primary determinants of the friction factor is the roughness of the inner surface of the pipe. Galvanized iron pipes often exhibit a relatively high level of roughness compared to other materials, such as PVC or copper. This rough surface can lead to increased turbulence in the fluid flow, resulting in a higher friction factor. Suppliers need to pay close attention to the manufacturing processes that can influence the surface finish of their pipes. Techniques such as improved galvanization methods or surface treatments could significantly reduce the internal roughness and thereby lower the friction factor.
