1. The galvanized wire in the hanger material is divided into hot-dipped galvanized wire and cold galvanized wire (electro-galvanized wire). The difference is: Hot-dip galvanizing is immersion plating in the molten and molten zinc liquid, the production speed is fast, and the plating thickness is not Uniform, the market allows a minimum thickness of 45 microns, up to 300 microns or more. The color is darker, consumes more zinc metal, forms an infiltration layer with the base metal, and has good corrosion resistance. Hot-dip galvanizing in the outdoor environment can be maintained for several decades. Cold galvanizing (galvanizing) is the use of current unidirectionality in the electroplating bath to gradually plate zinc onto the metal. The production speed is slow, the coating is uniform, the thickness is thin, usually only 3-15 microns, the appearance is bright, and the corrosion resistance is poor. Rusted for months. Relative hot-dip galvanizing, galvanized steel production costs are lower.
2. The wire is changed from hot-dip galvanized or electro-galvanized wire. The surface is smooth and bright, and its tensile strength becomes stronger. It is mainly used in the production of hangers, formulation, construction, medical, communications, weaving nets, brush making, high pressure hoses, wire binding, handicrafts and other aspects.
