Galvanized channel iron is essentially a steel channel that has undergone a hot-dip galvanization process, where a thin layer of zinc is applied to its surface. This zinc coating serves as a protective barrier, significantly enhancing the iron's resistance to rust and corrosion. The manufacturing of galvanized channel iron starts with high-quality steel, which is shaped into a channel form through a series of precise processes such as cutting, bending, and welding. After the channel has been formed, it is immersed in a bath of molten zinc, allowing the coating to bond effectively with the steel substrate.
