What Is Electrogalvanizing?

Electrogalvanizing

Electrogalvanizing is a process used to coat steel with a thin layer of zinc to enhance its resistance to rust and corrosion. This process involves electroplating, where an electrical current is passed through a saline or zinc-based electrolytic solution containing dissolved zinc salts. The steel acts as the cathode, and a zinc anode is also placed in the solution. As the current flows, zinc ions are deposited onto the steel surface, forming a smooth, uniform coating. This zinc layer not only extends the lifespan of the steel by protecting it from corrosion but also provides an attractive finish suitable for various applications.
