Hot-dip galvaning is a process in which the wire is dipped in zinc to create a zinc coating. Hot-dip galvanized steel wire has the advantages of corrosion resistance, good weather-resistance and long life, so it is widely used in many fields. The requirements for hot-dip galvanized steel wire are as follows: 1. Uniform galvanized layer: The galvanized layer of hot-dip galvanized steel wire should be uniform and dense, without defects such as uneven galvanizing, wrinkling, and falling off. 2. The thickness of the zinc layer is appropriate: the thickness of the zinc layer of the hot-dip galvanized steel wire should meet the standard requirements to ensure its corrosion resistance. 3. Good surface: The surface of hot-dip galvanized steel wire should be smooth, without obvious burrs and oxides. 4. Strong adhesion of galvanized layer: The galvanized layer of hot-dip galvanized steel wire should have good adhesion and not easy to peel off. 5. The chemical composition of galvanized steel wire is stable: the chemical composition of hot-dip galvanized steel wire should meet the relevant standards to ensure its quality stability. 6. The size of the galvanized steel wire is accurate: the diameter, strength and other dimensional parameters of the hot-dip galvanized steel wire should meet the standard requirements to ensure its performance. In short, the requirement of hot-dip galvanized steel wire is to ensure that its galvanized layer has good quality and stable performance, so as to improve its corrosion resistance and life.
