Leading manufacturers typically offer a range of galvanizing processes, such as hot-dip galvanizing or electro-galvanizing. Hot-dip galvanizing involves immersing the metal in molten zinc, resulting in a thicker coating that provides superior corrosion resistance. On the other hand, electro-galvanizing applies a thin layer of zinc through an electrochemical process, often resulting in a more polished finish, but may not offer the same level of protection as hot-dip galvanization.

Galvanization involves coating iron or steel with zinc to prevent rusting. While this treatment extends the life of pipes, it also alters their surface texture. The roughness created by the galvanization process can increase the friction factor compared to smooth-walled pipes. This increase implies greater energy requirements for pumping fluids through galvanized pipes, particularly in systems that rely on water or other low-viscosity fluids.
