Large coils of galvanized wire are divided into hot dip galvanized and cold dip galvanized. Hot dip galvanized wire is dark in color, consumes more zinc metal, forms infiltration layer with the base metal, and has good corrosion resistance. Hot dip galvanized wire can be maintained for decades in outdoor environment. Cold galvanized production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust.

The tensile strength of steel wire is high and the hardness is high. In the flattening process, the longitudinal movement resistance of steel wire per unit volume increases and the elongation decreases. The steel wire unit volume will move to the lateral resistance smaller, the width of the increase. On the contrary, the wire is easy to extend lengthwise, and its width decreases. This is the production of high steel wire hardness is easy to wide, small hardness, easy to stretch out of wide reasons. If the tensile strength deviation of steel wire is large, the hardness uniformity of steel wire strip is poor, the width difference of the billet rolled into large, will seriously affect the quality of the billet.

Once you find that the beginning of it has deformation, rust or broken problems must be timely correction. Generally speaking, the blade barbed rope will not be damaged simply, but it cannot be ensured that it will not happen. Because the local place where the blade barbed rope is required is generally outdoors, the probability of presenting an incident will be greatly increased. For example, in the plantation under the hillside, the blade barbed rope was damaged and deformed by stones rolling down the mountain, which requires manual correction in time, otherwise the deformed blade barbed rope will not only affect the beauty, but also lay hidden dangers for safety.
