What Are the Reasons for the Popularity of Galvanized Wire?

 49     0
Galvanized steel wire is often found in our lives for various purposes. Do you know anything about galvanized wire? The wire is galvanized to provide corrosion and rust protection, which ensures that the galvanized wire does not oxidize and is easy to use and aesthetically pleasing. It can be used in many applications, such as highway fences and wire mesh. In addition, its good toughness and elasticity make it highly resistant to impact. All these advantages make it attractive. Let's find out more about galvanized steel wire.

Hot-dip Galvanized Wire Knowledge

Hot-dip galvanized wire has a thick and uniform galvanized layer and is highly resistant to corrosion. In particular, hot-dip galvanized wire is processed using the hot-dip galvanizing process to produce a shiny wire with a decorative effect. In addition, hot-dip galvanized wire has good toughness and elasticity. Formed galvanized wire products can be bent and folded, can be applied to different environmental areas, and have good corrosion resistance. This is why it is being used more and more frequently in production life.


Hot-dip galvanized steel wire is used in a wide range of applications, such as fencing around tennis courts and playgrounds in schools and fencing on the sides of motorways, many of which are made from galvanized wire. Even the small ties on the outside of our simple gift packages are sealed with galvanized wire.

In addition to this, hot-dip galvanized wire products are widely used in chemical equipment, petroleum processing, marine exploration, metal structures, power transmission, shipbuilding, and other industries. In the agricultural sector such as house warming, and the construction industry for building mesh, floor heating mesh, wall mesh, and decorative mesh. It can also be used in the transportation industry for highway fencing, railway fencing, or binding some objects in daily life, etc.

What Are the Causes of Dezincification of Hot-dip Galvanized Wire?

The main objective of hot-dip galvanized wire is to prevent rusting and to extend the life of the wire and hot-dip galvanized wire products. However, there are some reasons why galvanized wire can become dezincified, which can be a particularly serious quality problem. So, what are the causes of dezincification?

1. The unclean surface of the wire can cause dezincification and cracking of the zinc layer after galvanization.
2. Hot-dip galvanized wire is hard, with a tensile strength of about 420 MPa.
3. Excessive oxidizing agent for hot-dip galvanized wire.
4. Excessive cathode current density of hot-dip galvanized wire.
5. Hot-dip galvanized wire cathodes and anodes touching each other.

These are the causes of the dezincification of hot-dip galvanized wire. Once the zinc layer is removed, the rust-proof effect of the wire is greatly reduced. And its service life will be reduced. When this happens, it is best to replace the aging galvanized wire. Galvanized wire does not cost much, and purchasing new galvanized wire will not cost much money. However, when you are choosing galvanized wire be sure to buy it from a reliable manufacturer. This will prevent you from buying a poor-quality product.

Electric Galvanized Wire Knowledge

Electro galvanized iron wire is gradually plated with zinc on the exterior of the metal by the unidirectional nature of the current in an electroplating bath. This process is uniformly plated and thin, usually only 3-15 microns in thickness. It has a brighter appearance but has relatively poor corrosion resistance and will generally rust within a few months.


Electro galvanized wire is used in a wide range of applications from the construction, metallurgical, and steel industries to the production of handicrafts and product packaging. It can be seen that it is used in a wide range of applications. Galvanized wire manufacturers produce a wide variety of types and specifications of flexible and tough galvanized wire to meet the needs of today's market. This has led to a further expansion of the market for galvanized wire. In short, it is well worth investing in.

How to Identify the Quality of Galvanized Wire?

Quality is an issue of concern to many people. This will directly relate to its longevity. So how can you buy high quality galvanized wire? Can you tell the quality of galvanized wire? As a galvanized wire manufacturer, Wanzhi Steel will teach you how to determine whether the quality is qualified or not.

1. Zinc Layer Adhesion

The standard galvanized wire coating adhesion requirement is that the zinc layer of the plated part should be firmly bonded to the base metal with sufficient adhesion strength and not fall off or bulge by the hammering test. If you buy a galvanized wire with a noticeably weak zinc layer, it is likely to be of inferior quality.

2. Zinc Layer Thickness

When the thickness of the commonly used galvanized wire is 3-4 mm, the zinc adhesion should be less than 460 g/m, ie the average thickness of the zinc layer should be not less than 65 microns. When the thickness of the plated part is greater than 4 mm, the zinc adhesion should be no less than 610 g/m, ie the average thickness of the zinc layer should be no less than 86 microns.

3. Find Expert Help

If you want to know if the quality of the galvanized wire is up to scratch, but don't have much knowledge about it. This is when you can seek the help of an inspection agency. They will help you to check its quality. Of course, you will need to pay the appropriate fees.

Causes of Rusting of Galvanized Steel Wire

Galvanized wire is very commonly used in practical applications. Some people think that galvanized wire does not rust, but this is not the case. Next, Wanzhi Steel will introduce the knowledge of galvanized wire to prevent rusting.

When the humidity in the atmosphere is higher than the critical humidity, a water film or water droplets will appear on the surface of the galvanized wire. If the atmosphere contains harmful impurities, collision with the water film or water droplets will intensify its corrosion.

Galvanized wire corrosion is caused by the chemical or electrochemical action of the surrounding medium. Depending on the medium, it is divided into atmospheric corrosion, soil corrosion, seawater corrosion, bacterial corrosion, etc. Atmospheric corrosion is more common, as the galvanized wire is in contact with the atmosphere during processing, transport, and storage, and there are always atmospheric corrosion conditions.

Corrosion or discoloration of galvanized wire in the atmosphere due to oxygen, water, and other impurities is called rusting or corrosion. Rusted galvanized wire products can affect the quality of appearance in mild cases and seriously affect the use or even lead to uselessness. Therefore, galvanized wire in storage must be properly stored. Remember not to store it together with corrosive substances to avoid rust. Also, store galvanized wire in a clean and ventilated location and pay attention to protection.
