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.

For buyers, establishing strong relationships within these social circles can significantly influence their purchasing decisions. Strong ties with factory representatives enable buyers to gain insights into production capabilities, lead times, and the availability of materials. This exchange of information often leads to more favorable terms and conditions when negotiating contracts.

Dalším významným aspektem je protiskluzová úprava povrchu, která zvyšuje bezpečnost při chůzi. Na schodových nášlapech se často uplatňuje perforace nebo drážkování, což výrazně snižuje riziko uklouznutí, zejména v deštivém nebo zasněženém počasí. Tím se galvanizované ocelové rošty stávají bezpečnějším řešením pro veřejné i soukromé schodiště.
