Common Gauge of Galvanized Steel Wire
Below is the common gauge of galvanized wire for your reference.
|Wire Gauge Size||SWG (mm)||BWG (mm)||AWG（mm）||Metric (mm)|
Note: The larger the number, the smaller the wire, for example, 12 gauge galvanized wire is thinner than 9 gauge. In general, lower gauge or thicker wire is best used for stronger projects. While higher gauge galvanized wire is suitable for garden and pet fencing.
How to Choose the Gauges of Galvanized Wire?
It is important to choose the correct size of galvanized wire. When you are ready to choose galvanized wire you should consider both strength and usage.
1. According to the Strength
What is the strength of galvanized wire you need? Generally, the wire gauge determines its overall strength or breaking weight. For example, 12 gauge low carbon galvanized wire has a breaking weight of about 500 lbs. While a 14 gauge GI wire has a breaking weight of about 800 lbs. You should be clear on how strong your project needs to be to better choose its gauge.
2. Depending on the Application
If you are going to use galvanized wire for fencing, we have some suggestions for you. When you’re fencing large, heavy animals, you might consider using sturdy 12 gauge or stronger 9 gauge wire. And thinner 16 gauge GI wire is ideal for garden fencing. Of course, the specifics should be determined by your actual use. If you have any questions, you can consult with Wanzhi Steel. Our experienced sales managers will give you the answer.
What Is Galvanized Wire?
Galvanized steel wire is steel wire which is coated with a zinc layer, which can protect the steel wire from rust and corrosion. Zinc can be applied using a method in which the wire is dipped into a molten bath of zinc or it can be electroplated on the surface. Due to its durability and smooth finish, it is suitable for many applications.
Can Galvanized Wire be Used Outside?
Yes. One of the most important properties of galvanized wire is its ability to resist rust. Therefore, it is well suited for outdoor use, such as the outdoor fences we commonly see. In the case of ungalvanized wire, for example, constant rain and wet weather can cause it to corrode quickly. Unlike galvanized wire, however, it can adapt to harsh weather conditions. It holds up well even in wet and salt-laden conditions.
Galvanized Wire Properties
Galvanized wire for sale has very many good qualities and characteristics. Next, Wanzhi Steel will take you to know more about it.
1. Flat and Smooth Surface
The galvanized steel wire improves the unevenness of the wire. The zinc layer is able to cover up the fine lines on the wire. This makes the surface of the wire appear flatter and smoother. It will be used for the garden fence will look particularly beautiful.
2. High Resistance to Damage
The bare steel wire can easily be scratched or otherwise damaged, which weakens the wire’s strength. But galvanized steel wire is different. The zinc layer on its surface provides a hard protective layer for the wire. The zinc layer provides a protective shield between the wire and the outside world, making it more resistant to damage than plain steel wire alone.
3. Flat and Smooth Surface
The galvanised steel wire improves the unevenness of the wire. The zinc layer can cover up the fine lines on the wire. This makes the surface of the wire appear flatter and smoother.
4. Good Toughness and Flexibility
Galvanized wire for sale is a kind of iron wire made by drawing using low carbon steel. Therefore, its toughness is excellent. Formed galvanized wire products can be bent and folded. It is also very elastic. It is very good to use this material to make springs.
5. Fire Resistant
GI steel wire is also common in industrial applications where there is a risk of fire. It is an indisputable fact that it remains strong in most fires. This is because when the wire is hot-dipped, the resulting zinc has an even higher melting point than regular zinc. The zinc layer’s resistance to melting helps prevent the steel inside the wire from reaching its own melting point.
Galvanized Steel Wire Uses
Galvanized steel wire is usually used as binding wire, fencing wire, etc. Due to its durability and bright surface, it is also used for supporting climbing plants, making crafts, etc. The wide applications also make the galvanized wire a promising investment project.
1. Fencing & Screen
GI wire is an ideal choice for making fences around houses, playgrounds, expressways, bridges, etc, which can secure your property. The common forms include razor wire and chain link fences on the market. Also, you can find fine filtration cloth or screens, such as insect screens.
2. Supporting & Binding
GI steel wire has excellent strength, which makes it a good binding material so that it is an ideal material for making gabions or slope stabilization.
3. Agriculture & Animal Husbandry
In the agricultural industry, galvanized steel wire can be supporting climbing plants, such as tomatoes, grapes, etc. It is known as garden wire. Besides that, GI wire is an ideal material for making cages or fencing for animals.
4. Other Industry
Galvanized iron wire also finds popular application in wire for telecom cable, making wire nails, ropes, tie wire or binding wire, and other daily use.
Types of Galvanized Steel Wire
According to the galvanizing process, GI wires are divided into hot-dip galvanized wire and cold galvanized wire (electro-galvanized steel wire). Below are more details for your reference.
Hot Dipped Galvanized Wire
Hot dipped steel wire is processed through a hot-dipped zinc bathing process. That is the wire is immersed in hot zinc molten so that the surface is fully covered with a zinc-coating layer. The hot-dip GI wire has excellent corrosion resistance, flexibility, and softness.
Manufacturing process: Steel rod coil — pre-treatment — wire drawing — rust removing — acid washing — thermal zinc coating — annealing — (wire re-drawing) –wire coiling — quality control — packaging.
Electro Galvanized Wire
The difference between hot-dipped and electro galvanized wire is the galvanizing process. The latter one uses the principle of electrolysis to paint a thin layer of zinc to the surface of steel wire. It makes the wire surface uniform and shiny.
Production process: Steel rod coil — pre-treatment — wire drawing ( wire redrawing) — rust removing — acid washing — cold galvanizing — wire coiling –quality control — packaging.
What Is Quality Galvanized Iron Wire?
Firstly, the wire surface should be smooth without sagging, dripping, slags, or other obvious defects. For example, the zinc leakage area should be less than 0.5 mm; Also, no more than 3 leakage spots per square centimeter.
Secondly, the zinc layer should be uniform and it should be firmly bonded to the base metal, which will not fall off or bulge through the hammer test.
Thirdly, the diameter tolerance should be within a reasonable range.
GI Wire Manufacturing Process
The production of GI wire is simple. We use steel rods as raw materials. Then the first step is to clean or pickle the wire rods to remove the oxides and impurities on the surface. After that, the descaled wire rods will go through wire drawing machines to make wires of the required size. These wires are often referred to as “black wires”. After being pickled and annealed, the wire will be galvanized, including hot-dipped galvanizing and electro-galvanizing. Then they will be rolled up into coils. You can package them up for sale after quality control.
Does Galvanized Wire Rust?
The answer is yes, but very slowly. Galvanized wire is much more corrosion resistant than black iron wire. The galvanizing process is a zinc coating applied on the surface of steel wire. It can prevent the steel wire from rusting for years because of the zinc oxide layer on the surface. However, when the zinc layer breaks down, rusting will be inevitable. But as mentioned, it is slow enough, say several decades, for your applications.
Galvanized Wire Price
When looking for galvanized wire for sale, it is inevitable to ask the price of GI wire. You can find the market price ranges from 400-1,500 USD. Actually, the galvanized wire price will be different with many factors, such as the diameter, the thickness of zinc-coating, galvanizing methods, suppliers, policy, etc. Commonly, thick galvanised wire and thin wire are of different prices. And the electro-galvanized wires will be cheaper than the hot-dip galvanized wires. With the cancellation of rebate tax and increasing shipping costs, the GI wire cost also rise greatly.
As an experienced galvanized wire supplier, we have some tips for you to save your money:
1. To choose suitable wires depending on the use environment and purpose. For example, the hot-dipped galvanizing wire will be a better choice for corrosive areas, such as chemical plants. Even the hot-dipped wire is more expensive but it is also more durable. In the long term, it will save your maintenance time and costs.
2. To buy from a reliable galvanized wire manufacturer. A qualified supplier always offers quality and enough products. For example, at Wanzhi Steel, all products are tested before shipment.
3. Based on your budgets. Cold galvanized wires are more affordable. If you have a tight budget, it will be a good choice.
4. Place your order at right time. As we know, the steel wire changes every day. Some customers would like to wait for a better price. But according to our experience, the price today will be the best price. More than that, at Wanzhi Steel, we will offer discounts for bulk orders. If you want more details, please contact us!
