É normal que o galvanizado enferruje.; caso contrário, a chapa de zinco é impura e contém impurezas como ferro. Além disso, o zinco protege outros metais, e o revestimento irregular de zinco expõe o metal interno, causando corrosão. Ou eles inadvertidamente entram em contato com outros metais, resultando em corrosão química.
Chapa de Aço Galvanizado a Quente 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.
Chapa de Aço Galvanizado a Quente 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.
