Shandong Rigang Supply Chain Management Co.,Ltd. Galvanized wire production process: It is processed by high-quality low-carbon steel wire rod, and the high-quality low-carbon steel is processed by drawing forming, pickling and derusting, high-temperature annealing, hot-dip galvanizing and cooling.
Galvanized wire characteristics: Galvanized iron wire has good toughness and elasticity, and the highest amount of zinc can reach 300 grams per square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.
Galvanized wire application: The products are widely used in various fields such as construction, handicrafts, weaving wire mesh, highway guardrails, product packaging and daily civilian use.
Galvanized wire is further divided into hot-dip galvanized wire and cold-dip galvanized wire (electro-galvanized wire), which are distinguished as follows:
Hot-dip galvanizing is dip-plating in a heated and melted zinc solution. The production speed is fast, and the coating is thick but uneven. The minimum thickness allowed by the market is 45 microns, and the maximum thickness can reach more than 300 microns. The color is darker, consumes more zinc metal, forms an infiltration layer with the base metal, and has good corrosion resistance. Hot-dip galvanizing can last for decades in outdoor environments.
Cold galvanizing (electrogalvanizing) is to gradually coat the metal surface with zinc through the unidirectional current in the electroplating tank. The production speed is slow, the coating is uniform, and the thickness is thin, usually only 3-15 microns. The appearance is bright and the corrosion resistance is poor. It usually rusts in a few months.
Compared with hot-dip galvanizing, the production cost of electro-galvanizing is lower.
