Production Process: The main production process of alloyed galvanized steel sheets (GA sheets) involves the strip steel, after exiting the zinc bath but before the coating solidifies, entering a zinc alloying furnace.

Steel companies, accounting for over 80% of the world's ferrous metallurgical industry capacity, employ the traditional long-process production technology of "sintering – ironmaking – steelmaking – rolling." This technology boasts advantages such as high efficiency and large-scale steel production

Aging – Changes in the physical and mechanical properties of low-carbon steel after a period of storage. Increased temperature accelerates the aging process.

Hot-dip galvanized coil (pure zinc coating) and hot-dip galvanized zinc-iron alloy coil (alloyed coating) are two key materials widely used in the field of steel corrosion protection. Although both are based on the hot-dip galvanizing process, they differ fundamentally in coating composition, microstructure, performance, and applications.

"Gray electrolytic" is a very descriptive colloquial term used in the steel industry to refer to alloyed hot-dip galvanized steel sheets (GA sheets). While not an official academic term, it accurately summarizes the key technological characteristics and appearance of this product.
