Hot-dipped galvanized wire (HDG wire), is made of high-quality low carbon steel wire rods (Q195, Q235). It is processed by drawing molding, pickling rust removal, high-temperature annealing, galvanizing, cooling, and so on.

Hot Dipped Galvanized Wire
A galvanized surface is a metal surface that has a zinc layer to prevent corrosion. We refer to the process of applying this zinc layer as "galvanizing". In addition, this application is done on a steel or iron surface.
Hot-dip galvanizing - where the item is immersed in molten zinc
Continuous galvanizing - a form of hot-dip galvanizing, but this method results in a thin layer of zinc; therefore, the corrosion resistance is relatively poor
Thermal spray - semi-molten zinc is sprayed onto the article
Electro galvanized wire - using the article and zinc metal as electrodes in an electrochemical cell
Mechanical plating - chemical method of depositing a coating using mechanical energy and heat
Electro Galvanized Wire
Hot galvanization is the process of coating metal with a zinc layer to protect it from corrosion. We can denote this as HDG. The process is divided into three main steps, as follows.
Surface treatment
Galvanizing
Inspection
In the surface preparation step, we have to suspend the steel piece using wire or place it on a suitable rack. After this, the steel undergoes three cleaning steps: degreasing, pickling, and flux. The degreasing step removes dirt from the steel surface. The pickling step removes oxidation and iron oxide. Later on, in the flux step, it removes any other oxides present on the steel surface and forms a protective layer that can prevent any further oxide formation.
During the galvanizing process, we need to immerse the steel in a zinc bath with a zinc content of at least 98%. Here, the iron on the steel surface tends to form a series of zinc-iron intermetallic compound layers and a pure zinc outer layer. In the inspection step, we need to check the coating. In addition, we need to determine the quality of the zinc layer on the surface.
Hot Dipped Galvanized Wire
Hot dipped galvanized wire is used in making cages, wire mesh, Cable armoring wire, construction, handicrafts, product packaging, and daily civilian and other fields. Also be used in various fields such as building, handicraft, wire mesh, galvanized hook net, wall screen, highway fence, product packaging, and daily civilian.
Hot-dip galvanizing is a type of galvanizing. The main difference between galvanizing and hot-dip galvanizing is that galvanized materials have a smooth and sharp surface finish, whereas hot-dip galvanized structures have a rough surface finish. In addition, the galvanizing process involves the formation of a layer of zinc to protect the metal from corrosion, whereas hot-dip galvanizing involves the formation of a pure zinc layer on the surface of the metal by surface treatment, galvanizing, and inspection.
