Hot - dipped galvaning is a process in which the wire is dipped in zinc to create a zinc coating. Hot - dipped 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 - dipped galvanized steel wire are as follows:

1. Uniform galvanized layer: The galvanized layer of Hot - dipped 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 - dipped galvanized steel wire should meet the standard requirements to ensure its corrosion resistance.

3. Good surface: The surface of Hot - dipped galvanized steel wire should be smooth, without obvious burrs and oxides.

4. Strong adhesion of galvanized layer: The galvanized layer of Hot - dipped 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 - dipped 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 - dipped galvanized steel wire should meet the standard requirements to ensure its performance.

In short, the requirement of Hot - dipped 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.
