  • Raw material of wire mesh sheet cold drawn low carbon steel wire base material can choose low carbon steel hot rolled disk bar or hot rolled smooth steel bar. The base material number and diameter of cold-drawn low carbon steel wire can be confirmed according to the rules in the table below. During the cold drawing process, the surface shrinkage rate of each drawing should not be greater than the wire mesh before cold drawing. Annealing shall not be carried out during wire drawing. If butt welding is required, the same production unit and base material of the same number should be selected. The appearance quality of wire mesh should not affect wire drawing. When the welding function is poor or brittle fracture occurs, special inspection should be carried out according to relevant standards.

  • In general, the cost of hot dipping zinc is lower than that of other maintenance coatings. The reason is very simple. Other maintenance coatings, such as sand painting, are labor-intensive processes, whereas hot dipping zinc processes are highly mechanized and tightly controlled in-plant construction. Hot dip zinc coating can be visually and briefly tested for non-destructive coating thickness.

  • Galvanized wire can be seen as iron wrapped in carbon, when extinguished, the surface is comparable to shallow carbon can contact with oxygen, produce carbon dioxide gas, will wrap it in iron (this is a molten state) radiation in. The more carbon there is in the galvanized wire, the more likely it is to spark. The iron-encased carbon is like dynamite in a dynamite bag, blowing the iron away from time to time.

  • The key and important parts with tensile strength greater than 1034Mpa should be relieved of stress at 200±10℃ for more than 1 hour before plating, and the carburized or surface hardened parts should be relieved of stress at 140±10℃ for more than 5 hours. The cleaning agent used for cleaning shall have no effect on the binding force of the coating and no corrosion on the substrate. Acid activation Acid activation solution should be able to remove corrosion products and oxide film (skin) on the surface of parts without excessive corrosion on the matrix.
