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.
