Steel wire rod is a semi-finished product produced from a steel billet. The wire is a final product for the manufacturing plant, and it is considered a raw material for the wire product manufacturing workshops.
All kinds of wires
The variety of wires depends on the type of wire. In this section, we examine the types of steel wire:
• Black wire
Black wire or reinforcing wire is a steel wire that has a good ability to bend and twist. This type of wire with good resistance can be twisted, woven or returned to its original state. Black wire is produced from low carbon steel, so it has high plasticity. In general, it can be said that the plasticity of black wire is very good, but its resistance to corrosion is negligible. In picture number 3, we see a coil of black wire. Considering that black wire has no coating, it is highly susceptible to corrosion. Black wire usually rusts when exposed to air. The effects of rust are always visible on the black wire in the form of red spots.
• Galvanized wire
Galvanized wire is obtained by galvanizing black wire. This type of wire can be used for wet environments. Galvanized wire is produced in two ways: hot galvanized or cold galvanized. Hot galvanized wire is completely integrated and shiny, and in general, it can be said that the quality of cold galvanized wire is lower than hot galvanized wire.
Hot galvanized wire:
When black wire is immersed in a molten bath of zinc metal and galvanization is applied with great depth on the surface of the metal, this product is called hot galvanized wire.
• Cold galvanized wire:
In the cold galvanizing process of the wire, like other steel products produced by the cold galvanizing process, the black wire is plated using the electrolysis method. The depth of galvanization in this case is less than hot galvanization. Image number 4 – depicts cold galvanized and hot galvanized wire.
• PVC wire
PVC wire is the same black wire that is coated with PVC materials during the coating process. Wire coating operation is done by wire coating machine. This type of wire has a high resistance to corrosion and rust, at the same time, it has a high formability.
• Stainless steel wire
Stainless steel wire is another type of steel wire. This type of wire has a high resistance to rusting. The price of stainless steel wire is higher than the price of black wire or galvanized wire. Basically, steel products made of stainless steel have a higher price than the price of steel products produced from carbon steel. Therefore, the use of stainless steel wire is in places where there is no other option other than using this type of product in terms of engineering and economics. Stainless steel wire is also called non-stick wire. The reason for this designation is that stainless steel products do not have magnetic properties and are not attracted to magnets due to their special crystal structure.
Application of wire
It is not possible to reach a general conclusion about the applications of wire. Due to the flexibility of this product, many applications are considered for wire. Also, the range of wire materials makes its applications more widespread. The following items that can be seen in the list of wire applications are mentioned in general and each of them can have limitations depending on the type of wire. For example, where wire is used to close the mold temporarily, there is no need to choose galvanized wire. Where the production of press mesh is considered, it is not possible to use very soft wires with low thickness, and in the same way, the type of wire should be considered according to its efficiency.

The following list shows the most common applications of wire:
1. Closing different parts of reinforcement
2. Closing galvanized rabbets
3. Production of welding wire
4. Production of springs
5. Production of various types of nets, including fence nets, chicken nets, gabion nets, French nets and press nets $@ |%Production of linear and circular barbed wire as a straight wire or related barb connected to it
6. Closing different parts of the mold to enclose the concreting area
How to produce wire
Wire is classified into two types in terms of production method, which are fabric wire and tensile wire. Fabric wire, as its name suggests, is the wire produced in the factory directly. This type of wire is produced using the hot rolling process in the factory and is presented in the same way in the market
