Galvanizing is a technique where a layer of zinc is applied to the metal surface to protect it from oxidation and harsh environmental effects. After coating, the pickaxe blades become not only shinier but also highly resistant to corrosion, significantly extending their lifespan and reducing maintenance costs.
Proper zinc coating also gives the tools a more professional finish, making them suitable for export and high-demand markets. This short video offers a close-up view of a modern metal finishing line, emphasizing both the science and artistry behind this critical industrial process.
