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.

Roofing granules refer to roofing materials with high reflectivity, which can reflect most of the sunlight and reduce the heat absorbed by the building. Among them is white roofing granules, whose advantages lie in their excellent energy-saving effect and ability to reduce the urban heat island effect. In the hot summer, white roofing granules can significantly reduce the indoor temperature and reduce the use of air conditioning, thereby saving energy.
