Hot dip galvanizing processing galvanizing also called hot dip galvanized and hot dip galvanizing: is an effective way of metal corrosion, mainly used for the metal structures and facilities. Will rust of steel parts are immersed into around 500 DEG C melting liquid zinc, steel pieces attached to the surface of the zinc layer, so as to prevent corrosion. Hot dip galvanizing process: refined pickli...
