What Is Galvanized Wire?

Galvanized wire is a type of steel wire that is coated with a layer of zinc. It has the characteristics of anti-corrosion, weather resistance, acid and alkali resistance, so it has an important role in many fields. Galvanized iron wire is widely used in construction, agriculture, industry and households.

As an experienced galvanized wire manufacturer, Shengsen Metal has a daily output of 260 Tons, and has been supplying customers over 40 countries. To help you get a full idea of what galvanized wire is, following I’ll show you how it’s made in our production center.

How Is Galvanized Steel Wire Made?

It’s the zinc coating process that makes the wire galvanized wire. But there are still few essential steps to prepare the wire before galvanization. We’ll start with the raw materials.

Firstly, the wire material preparation stage is carried out by selecting high quality mild steel wires as raw material. Here you can see the raw material in our warehouse. These wires are surface cleaned and degreased to remove surface impurities and grease.

Then the wire rod undergoes a drawing process to obtain the required diameter and strength.This drawing gradually reduces a certain diameter while increasing its strength and hardness. This step ensures the consistency and qualified physical properties of the wire.

After drawing, the wire is immersed in an acidic solution, such as hydrochloric acid, to remove iron oxide and other impurities from the surface. Pickling improves the adhesion of the galvanized layer to the wire and ensures the quality of the galvanization.

Now we come to the most important part, galvanizing the wire. The common types of galvanizing are electro-galvanizing and hot-dip galvanizing. Both of these methods can galvanize the wire, but the thickness of the zinc layer varies due to the different processes.

Hot-dip galvanized wire is a steel wire that is dipped in molten zinc after pickling. By means of hot dip plating, the zinc reacts with the surface of the wire to form a zinc-iron alloy, which protects the wire from corrosion. After galvanizing, the wire is passed through cooling equipment to cool it down quickly. Cooling helps the zinc layer to solidify and cure to ensure uniformity and stability of the galvanized layer.

For electro-galvanized wire, the steel wire will be immersed in the electrolyzer containing zinc ions. Steel wire as the cathode, zinc ions in the electrolyte is reduced and deposited on the surface of the steel wire, forming a layer of uniform, dense zinc layer. Upon completion of electroplating, the remaining electrolyte and impurities need to be cleaned to ensure the quality of the galvanized iron wire. The cleaned wire is then fed into a drying facility to remove moisture.

During our production process, galvanized iron wire is inspected several times to ensure that its quality meets the standard requirements. Inspection includes appearance check, size test, galvanized layer thickness measurement and so on. Only the iron wire that passes the inspection can enter the next step of packaging.

All galvanized wire will be packaged according to customer needs, usually in rolls or bundles. This ensures that the gi wire is not damaged during transportation and storage and is easy to use.

These are the main steps of galvanized wire production process. Through reasonable process and strict quality control, galvanized iron wire products with stable quality, good anti-corrosion performance and high mechanical strength can be produced. Both hot-dipped galvanized wire and electro-galvanized wire are widely used in construction, agriculture, industry and household to meet the needs of different fields.

What Is Galvanized Wire Used For?

Through the whole production process of galvanized wire, now we all know it’s strong, rust-resistant and multi-purposeful. So you can use it in various industries and application.

Protection

With our 20 more years of experience for galvanized wire manufacturing and exporting, there are a number of clients purchase it for fence production. The fence industry has always been very profitable and the market is constantly growing.

Shengsen metal makes perfect wire solution for our customers, from different wire tensile strength, various wire gauge, zinc coating from 40g to 300g for different fence production. You can easily make most wire mesh fences like chain link fence, welded wire mesh fence panel, warehouse security fence, and welded wire mesh fence with our galvanized wire.

Binding

Another frequent use by our customers is in wire binding for construction. Galvanized wire is widely used as binding wire material in the construction industry due to its excellent corrosion resistance, high strength, durability and ease of construction.

The zinc layer on the surface effectively prevents the wire from oxidizing and rusting, and enhances weathering durability, ensuring stable use in a variety of environments and not easy to deform and rupture.

At the same time, galvanized binding wire is cost-effective, both economical and practical, and is applicable to a variety of scenarios, such as building frame binding, scaffolding, formwork system reinforcement, etc., showing good economic benefits and wide applicability.

Agriculture

Beyond security and construction, there are several customers in the agricultural industry who purchase our galvanized wire for support and repair.

In agricultural, galvanized wire is commonly used in irrigation systems, construction and repair of pesticide sprinkler equipment, greenhouse construction, and fencing. This is because of its strong corrosion resistance and ability to maintain stable mechanical properties over time in harsh environments such as humidity and soil contact.

For the farming industry, galvanized wire can be used to make animal fences, poultry cages, livestock farms, zoning isolation netting and other facilities to provide safe and reliable enclosure conditions. Especially, customers in south america prefer the galvanized oval wire.

Daily Use

In addition to the commercial uses mentioned above, galvanized wire also plays an important role in everyday life. For example, it is used for baling, making handicrafts.

In baling purposes, galvanized wire can securely bind all kinds of items due to its good toughness and tensile strength, preventing loosening or breaking during transportation. In crafts, galvanized wire is widely used for basket weaving, home decorations, gardening and other creative crafts because of its bright metallic texture and durability.

Does Galvanized Wire Rust?

Yes, galvanized wire do rust. Although galvanized wire has been specially treated to improve its anti-corrosion properties, it may still rust under certain conditions. The main causes of this rust include:

1. Zinc depletion (long-term wear and tear or corrosion leads to thinning or loss of the zinc layer, exposing the iron substrate to air and moisture).
2. The effects of humidity and corrosive environments (high humidity tends to promote the formation of a water film, which accelerates corrosion of both the zinc layer and the iron substrate).
3. Temperature and temperature differences (high temperatures accelerate the corrosion reaction, and temperature-induced condensate increases the risk of corrosion).

Therefore, the thickness of zinc layer and quality of galvanization in production is quite important during manufacturing. On the other hand, choose the right galvanized wire specification for your project is the key when buying it.

To prolong the service life of your galvanized wire, Shengsen has experiences in providing high quality galvanized wire. You can consult our wire experts with your applications and the environment it will be used. I’m sure you will get the most suitable solution.

Where to Buy Galvanized Wire?

So, where to buy galvanized wire anyway？If you are buying for small amount, the best choice is the local hardware store, they often have stock for this basic but verstile wire product.

When you have consumptions like 10 tons or 100 tons more per year, it’s the time to consider costs and increasing revenue by sourcing worldwide. As a reputable galvanized wire manufacturer from China, Shengsen Metal has been supplying customers in more than 40 countries with different solutions.
