Galvanized Steel Wire Manufacturer in China
Galvanized steel wire can be known as a steel wire with a simple design in the form of a circular cylinder. The process and stages of creating galvanized steel wire involve drawing and hot-dipping metals to create electroplated zinc or can also be created by hot-dipping to produce high-quality galvanized steel wire products.
The resulting products will have many different designs, so they are widely used in various fields such as manufacturing, construction, or daily life.
It is known that galvanized steel wire can be considered a more commonly used item. This type of wire is mainly made from pure carbon steel material.
Speaking of the structure, a galvanized steel wire will be made up of 6 twisted strands. Each strand will be connected through small steel wires, and the number of wires to make one strand usually ranges from 12 wires, 19 wires, 36 wires to 37 wires…
Therefore, when the structure of the strands has more small steel wires combined, the diameter of the galvanized steel wire will be larger. In the formula for calculating the diameter applied in galvanized steel wire manufacturing plants, the strength, load-bearing capacity, and durability of the wire will be proportional to its achieved diameter.

Galvanized Steel Wire Properties
Cost-effectiveness
Galvanized steel wire offers a cost-effective solution compared to stainless steel, providing good durability and performance at a lower price.
Strength and Durability
Galvanized steel wire maintains high tensile strength, making it durable and suitable for heavy-duty applications such as fencing, construction, and industrial uses.
Corrosion Resistance
The galvanization process involves coating the steel wire with zinc, which protects it from rust and corrosion. This makes it suitable for outdoor applications and environments with moisture.
Flexibility
Depending on the gauge, galvanized wire can be flexible, allowing for easy installation and shaping in various applications, such as crafting and binding.
How to Choose the Specification of GI Wire?
1. According to strength
What is the strength of galvanized wire you need? Generally, the wire gauge determines its overall strength or breaking weight. For example, the breaking weight of 12-gauge low-carbon galvanized wire is about 500 pounds. And the breaking weight of 14-gauge GI wire is about 800 pounds. You should know how strong your project needs to be so as to better choose its specification.
2. Depends on the application
If you plan to use GI Wire for fencing, we have some suggestions. When you are fencing large, heavy animals, you can consider using a sturdy 12-gauge or a stronger 9-gauge wire. The thinner 16-gauge GI wire is ideal for garden fencing. Of course, the specific situation should be determined according to your actual use. If you have any questions, you can consult us.
Types of Galvanized Steel Wire
Types of galvanized steel wire
According to the galvanizing process, galvanized steel wire is divided into HDP wire and cold-dip galvanized wire (electro-galvanized steel wire).
1. Hot-dip galvanized wire
It is processed by hot-dip galvanizing process. That is, the wire is immersed in hot zinc melt so that the surface of the wire is completely covered with a layer of zinc coating. Hot-dip galvanized wire has excellent corrosion resistance, flexibility and softness.
Manufacturing process: Steel bar coil-pretreatment-wire drawing-rust removal-pickling-hot-dip galvanizing-annealing-(heavy drawing)-winding-quality control-packaging.
2. Electro-galvanized wire
The difference between hot-dip galvanized wire and electro-galvanized wire lies in the galvanizing process. The latter uses the principle of electrolysis to coat a thin layer of zinc on the surface of the steel wire, making the surface of the steel wire uniform and shiny.
Production process: Steel bar coil-pretreatment-wire drawing (heavy drawing)-rust removal-pickling-cold galvanizing-winding-quality control-packaging.

Notes: the larger the number, the thinner the wire. For example, GI 12 wire is thinner than GI 9 wire. In general, lower-gauge or thicker wires are best for stronger projects. At the same time, higher specifications of GI wire for gardens and pet fences.

Does galvanized steel wire rust?
Galvanized wire is highly resistant to rust because of the protective zinc coating that keeps moisture away from the steel beneath.
The zinc coating offers what is called cathodic protection. Zinc is more reactive than steel, so it corrodes first, protecting the steel and extending the lifespan of the wire. Superior corrosion resistance and longevity are the main benefits of galvanized wire.
To put it simply, yes, galvanized wire rusts, but not very quickly.
How to cut galvanized steel wire?
The method of cutting galvanized steel wire depends on the wire’s thickness, with wire-cutting diagonal shears being suitable for wires thicker than 18 AWG, and diagonal shears or the cutting edge of needle-nose pliers being suitable for smaller-diameter wires measuring 18 AWG or thinner.
How to solder galvanized steel wire?
1. Choose the right welding method: According to the thickness, shape and purpose of the galvanized iron wire, choose a suitable welding method, such as manual arc welding, metal arc welding, resistance spot welding, etc.
2. Use the right welding materials: Choose the right welding materials, such as welding rods, welding wires, flux, etc., to ensure the mechanical properties and corrosion resistance of the weld. Generally speaking, the zinc content of the welding material should be lower than that of the parent material to reduce the generation of pores and cracks. When welding galvanized iron wire, a welding rod or welding wire specially used for welding galvanized materials should be selected.
3. Treat the galvanized iron wire before welding: Grind the welding part with sandpaper to remove the zinc coating and oxides, thereby improving the welding quality. However, it should be noted that grinding may destroy the anti-rust property of the zinc coating, so anti-rust treatment is required after welding.
4. Control welding parameters: According to the requirements of the welding method and welding materials, control the welding current, voltage, welding speed and other parameters to ensure the welding quality.
5. Use appropriate welding technology: such as preheating before welding and slow cooling after welding, etc., to reduce welding stress and cracks.
6. Take protective measures: During the welding process, wear protective glasses, masks, gloves, etc., use exhaust equipment, ventilation equipment, etc. to reduce harm to the human body and the environment.
7. Perform post-weld treatment: After welding, the weld should be polished, cleaned, etc. to remove oxides and impurities on the weld surface and improve the corrosion resistance of the weld.
It should be noted that the welding of galvanized iron wire may produce toxic smoke and dust, which is harmful to the human body and the environment. Therefore, effective protective measures need to be taken during the welding process, such as wearing protective glasses, masks, gloves, etc., using exhaust equipment, ventilation equipment, etc., to reduce harm to the human body and the environment. At the same time, due to the presence of the galvanized layer, anti-rust treatment after welding is also very important to prevent the weld from rusting and corrosion.
