Hot dip galvanized coating is also relatively thick, but there is an uneven situation, for example, the thickness of the thin is only 45 microns, thick can reach 300 microns or even thicker, the color of this product is relatively dark. There is also a lot of zinc consumed in the production process. Zinc will form an infiltration layer with the metal. Its advantage is that it has good corrosion resistance. Electrogalvanizing, it is through the plating tank in the zinc one-way plating on the outside of the metal products, this way of making products is relatively slow, but its thickness is more uniform.

This method is generally the use of hot rolled laminated plate as raw material, the annealed steel plate is first sent to the pickling workshop, with sulfuric acid or hydrochloric acid to remove the surface of the steel sheet oxygen hot galvanizing method. After pickling, the steel plate immediately enters the tank to soak and wait for galvanized, which can prevent the reoxidation of the steel plate. After pickling, water cleaning, squeeze dry, drying, into the zinc pot, the temperature has been maintained at 445-465℃.

Specific requirements for the safety of galvanized wire production: clean up all tools and other objects that hinder production in the galvanized wire production environment. Operators in the pickling process, pay attention to the action should be careful, not careless, into the pickling tank must be handled lightly, to prevent splashing on the body. When adding acid, the acid must be slowly poured into the water. It is forbidden to pour the water into the acid, so as to prevent the acid from splashing out and hurting people. Do not hurt yourself or others.
