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.

1. Reputation and Experience Look for manufacturers with a proven track record in the industry. A reputable manufacturer is often backed by years of experience and positive customer reviews. They will typically have established relationships with suppliers and a deep understanding of the market's demands.

Hot-dip galvanizing entails immersing the prepared metal in molten zinc, resulting in a thick, durable coating that provides excellent corrosion resistance. On the other hand, electro-galvanizing uses an electric current to bond the zinc to the surface, producing a thinner but more uniform layer. Once the galvanization is complete, the windows undergo further processes such as painting or powder-coating to enhance their aesthetics while providing an extra layer of protection against weather elements.
