The diameter of cold-drawn wire should conform to the contract, check whether the amount of zinc meets the requirements of the contract, check the tensile strength, and ask the factory to provide the corresponding inspection report. The wire factory introduces that the weight of a single coil of wire of different specifications should not be lower than the volume weight required by the contract, and record the value. No contacts are generated for each reel of wire. If there are contacts, no more than three contacts are generated for each reel. Each contact should be smooth surface treatment, the wire can not be pulled off from the contact, in line with customer packaging requirements.

Every time galvanized wire production enters the peak season of the industry, the road leading to the factory will see from time to time transport wire and container vehicles, as well as galvanized bright wire short-distance transport trucks, driving the labor utilization rate in the surrounding countryside, solving the employment problem of most people. Galvanized wire is divided into hot dip galvanized wire and cold galvanized wire difference: hot dip galvanized is in the heated melting zinc liquid dip plating, production speed is fast, the coating is thick but not uniform. Dark color, consumption of zinc metal, and matrix metal formation of infiltration layer, good corrosion resistance, hot dip galvanizing in outdoor environment can be maintained for decades.

This method is generally the use of hot rolled laminated plate as raw material, the annealed steel plate is first sent to the pickling workshop, with sulfuric acid or hydrochloric acid to remove the surface of the steel sheet oxygen hot galvanizing method. After pickling, the steel plate immediately enters the tank to soak and wait for galvanized, which can prevent the reoxidation of the steel plate. After pickling, water cleaning, squeeze dry, drying, into the zinc pot, the temperature has been maintained at 445-465℃.
