Quality test report and parameters of galvanized iron wire
The galvanizing process is to coat ordinary iron wires with a layer of zinc to extend their service life. Iron is very prone to corrosion and rusting. Zinc is a metal that is not easily rusted. By using special equipment and processes to deposit zinc on the surface of iron, it can resist corrosion and is less prone to rusting. Zinc has higher stability than iron and is also less prone to rusting in humid environments. Galvanized wire can be divided into two categories due to different production processes: hot dip and cold dip. Galvanized wire is widely used in various fields such as construction and packaging due to its good toughness and elasticity. Iron wire galvanizing equipment comes in handy during galvanizing.
Galvanization process
The processing of galvanizing process is very complicated, and the reason why it can be applied in many places is because of the excellent performance and strict processing steps of galvanizing process, which ensures the safe use of users with good quality. Therefore, galvanized flat wire has been widely used in our daily life. It is processed from high-quality low-carbon steel wire rods, and the galvanized round wire is divided into hot-dip galvanized wire and cold galvanized wire (electroplated zinc wire). It is made of high-quality low-carbon steel, which is drawn, pickled, rust removed, high-temperature annealed, and hot-dip galvanized. Processed through cooling and other technological processes. The product is widely used in various fields such as construction, handicrafts, weaving silk screens, making galvanized flower nets, plastering wall nets, highway guardrails, product packaging, and daily civilian use.
Galvanized wire is commonly used in our daily lives. It is made from high-quality low-carbon steel wire rods and processed through processes such as acid washing, rust removal, drawing, high-temperature annealing, and hot-dip galvanizing. Galvanized wire has good toughness and elasticity. Due to the galvanizing process, it has strong corrosion resistance and is widely used in construction, handicrafts, woven nets, highway guardrails, and other fields. Galvanized wire can be divided into hot-dip galvanized wire and cold dip galvanized wire according to different production processes. Hot dip galvanized wire refers to the process of immersing zinc in a molten zinc solution that has been heated and melted. The production speed is fast, but the thickness of galvanized wire varies, consuming more zinc metal. The corrosion resistance is good because the base metal forms an infiltration layer, which can be used for decades in outdoor environments.
Galvanization process
The galvanizing process is to gradually coat the metal surface with zinc through unidirectional current in the electroplating tank. The production speed is fast, the galvanized layer is uniform, and the appearance is bright. However, it has excellent corrosion resistance and generally does not rust for several years. Because the amount of galvanizing used for hot-dip galvanizing and cold galvanizing is different, it can be directly distinguished by its appearance. The color of cold galvanizing is shiny, silver white with yellow, while the color of hot-dip galvanizing is shiny and white.

We usually conduct testing based on the specific requirements of the customer, but in general, we test the tensile strength, elongation, and galvanized layer indicators of galvanized iron wire to see if the overall galvanized iron wire meets the customer’s quality requirements rather than international or national standards.
