Technical difference between hot galvanizing and cold galvanizing

Technical differences between hot galvanizing and cold galvanizing:
The corrosion resistance of hot galvanizing is much higher than that of cold galvanizing. Hot galvanizing will not rust in a few years, cold galvanizing will rust in half a year!
The cold galvanizing process is used to protect the metal from corrosion. For this reason, the coating with zinc filler is applied to the protected surface by any coating method. After drying, the coating with zinc filler is formed. The content of zinc in the dry coating is 95%. The steel is galvanized on the surface under the condition of cooling, while the hot-dip galvanizing is the galvanizing on the surface of the steel pipe under the condition of hot-dip galvanizing, which has strong adhesion and is not easy to fall off. Although the hot-dip galvanizing pipe is also rusted, it can meet the technical and health requirements in a long period.
