Ia adalah perkara biasa untuk tergalvani untuk berkarat.; jika tidak, plat zink adalah najis dan mengandungi kekotoran seperti besi.

Atau mereka secara tidak sengaja bersentuhan dengan logam lain, mengakibatkan kakisan kimia.
Kepingan Keluli Tergalvani Hot Dip will also rust, but the galvanized layer is oxidized first to protect the steel sheet from rusting, and its service life is longer. In addition, the chrome-plated chrome layer will not react with oxygen, carbon dioxide, and water in the air under natural conditions, nor will it be corroded by weak acids and alkalis. Its anti-rust effect is better.
Kepingan Keluli Tergalvani Hot Dip will not rust in a typical environment, but it may rust due to improper storage, scratches and bumps, water intrusion, and steam fumigation. Galvanized sheet rusts because zinc is corroded, protecting other metals. Otherwise, the zinc plate is impure and contains impurities, such as iron.
