Large roll galvanized wire is made of low carbon steel wire rod processing, after drawing forming, pickling rust removal, high temperature annealing, hot galvanized. It is processed by cooling and other technological processes. Large roll galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire).
Hot-dip galvanizing wire: hot-dip galvanizing is dipped in the heated melting zinc liquid, the production speed is fast, the coating is thick but not uniform, the market allows the lower thickness of 45 microns, up to 300 microns or more. The color is dark, the consumption of zinc metal is more, the infiltration layer is formed with the base metal, the corrosion resistance is good, and the hot dip galvanizing can be maintained for decades in the outdoor environment.
Cold galvanized wire: cold galvanized (electric galvanized) is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, the production speed is slow, the coating is uniform, the thickness is thin, usually only 3-15 microns, the appearance is bright, poor corrosion resistance, generally a few months will rust.
Modified wire drawing is made of hot galvanized wire or electro galvanized wire (also known as galvanized wire drawing), the surface is smooth, bright, and the tensile strength becomes stronger. It is mainly used for making clothes hangers, making, construction, medical treatment, communication, net weaving, brush making, high pressure pipe, tying wire, handicrafts and so on. Low carbon steel coil wire with excellent corrosion resistance and smooth and flawless surface quality, has been widely used in many leisure and entertainment places, families, enterprises and so on.
The difference between galvanized wire and modified wire drawing: galvanized wire cost is higher than modified wire drawing cost; Galvanized wire has longer life than modified wire drawing. The surface of the modified wire is brighter than that of the galvanized wire (hot dip galvanized steel wire), but the zinc content of the galvanized wire is more than that of the modified wire. The surface of the modified wire (cold galvanized steel wire) is smooth and bright, and its tensile resistance is strong. Galvanized wire is resistant to high temperature and corrosion.
