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.

The quality of the galvanized layer can be evaluated by the weight of the zinc plated on the substrate, the bonding force between the galvanized layer and the substrate, and the uniformity of the coating. The uniformity of the zinc layer is an important quality indicator of the zinc coating. In general, the corrosion always starts at the thinnest part of the zinc layer and spreads around, resulting in rust, broken wires and affecting the service life. For the coating weight and bonding strength, each standard has clear regulations, but the uniformity is different. In the 1970s, the ISO standard and the standards of various countries in the world generally stipulated that the copper sulfate test should be used for inspection. By the 1980s, with the exception of Japan and the former Soviet Union, ISO standards and standards around the world no longer adopted this method. Although our country has retained this method in some standards such as GB/T15393-94 "Steel wire galvanized layer" in the form of "can be carried out by mutual agreement", most of them are no longer adopted. However, the old zinc coating uniformity detection method has been abandoned but no corresponding new methods have been established. In addition, there is no uniform definition and requirement for uniformity, so that some producers do not monitor and detect the uniformity of the coating well. , So as to affect the further improvement of product quality

1. Strand wire should have the same diameter, the same intensity, and the same level of zinc coating.
The diameter and the lay length should be uniform, and have no loose after cutting
Strand wire should be tight; they should not be staggered, and have no breaking and bending.
2. Strand wire and the overhead ground wire of 1 * 3 are not allowed to connected, other types of strand wire should be connected with welder. The distance between any two joints shall not be less than 50m; the measures should be taken to prevent the joints eroding.
3. Mechanical Properties
it should follow the 5.3 mechanical requirements in "People's Republic of ferrous metallurgy industry standard YB/T5004-2001.
4. Coating quality
4.1 Galvanized steel's surface should be coated with uniform continuous layer of zinc, without cracks and open spots
4.2 Zinc coating of the steel can have white spots, flash point and the individual accumulation of zinc layer, but can not affect the use. But the value of the local wire must not exceed 2 times as large as the positive deviation of the diameter.
4.3 The coating quality of the strand wire with the split shares should meet the following table:
4.4 The zinc coating should be firmly enlaced 6 laps on the mandrel in the above table, no cracking or the zinc coating layer. It can not be able to wipe with the extent of bare fingers.
5. Refer to "the People's Republic of ferrous metals industry standard YB/T5004-2001 galvanized steel wire¡±.
"People's Republic of ferrous metallurgy industry standard YB/T183-2000 strand of rare earth alloy coating¡±.

1. The steel of the strand wire shall be used in the requirement of YB/T699-1999. The steel grades are 5 # or 50 #.
2. Zinc ingot, used in galvanized steel wire, should use the zinc in GB/T470 of 0 or 1.
(C) Factory inspection and testing methods
all the factory inspections are divided into full inspection and spot inspection. Full inspection requires checking the appearance, structure, diameter, galvanized coating mass, twist method and its quality of each steel stranded wire.
1. Inspect the surface quality of the strand by visual inspection.
2. Use the measuring tool of 0.1mm to inspect the diameter of the strand.
3. Breaking load test is required according to the standard GB/T8358-1987.
