The selection of the appropriate type of galvanized wire depends on the project site&#;s weather conditions, applied forces, expected life, and available budget. It is recommended to consult with experts to choose the best option for your project.
Galvanization Process: How to Produce Resistant Wire
One of the most important advantages of galvanized wire compared to other types of wire is its high resistance to corrosion and adverse weather conditions. This resistance is achieved through the galvanization process, in which a thin layer of zinc is coated on the surface of the base metal (usually steel). In the following, we will discuss the details of this process and how resistant wire is produced.
Hot-Dip Galvanization Process:
- Pre-treatment: First, the steel wire must be completely clean and free of any contamination, such as oil, grease, or rust. This step is usually done using an acidic or alkaline solution.
- Acid pickling: After cleaning, the steel wire is immersed in a bath containing hydrochloric acid or sulfuric acid to completely wet its surface. This ensures that the zinc particles adhere better to the metal surface.
- Molten zinc bath: The steel wire enters a bath containing molten zinc at a temperature of about 460 degrees Celsius. At this stage, a layer of zinc settles on the metal surface and combines with it.
- Cooling: After exiting the molten zinc bath, the galvanized wire should be slowly cooled to stabilize its molecular structure.
- Quality control: Finally, the quality of the galvanized layer is examined in terms of thickness, continuity, and adhesion to ensure compliance with established standards.
Cold Galvanization Process:
This method is suitable for wires with smaller diameters and is performed at a lower temperature than the hot-dip method. In cold galvanization, the surface of the steel wire is first coated by electroplating and then immersed in a zinc solution to form the zinc layer.
