<p>In fact, the galvanizing process is very common in other nail products. Steel row nails, gun nails, floor nails, etc. all need to be galvanized. The main function of the galvanizing process is also to prevent rust, and the other is to make the surface of the nail look smooth and bright, with silver glitter.
