Commonly found galvanized low carbon steel wire on the market ranges in size from # 6 to # 36, and its sizes are expressed not only in millimeters but also in gauge. Wondering how to find the suitable galvanized iron wire for your project? SUNSHINE Group will give you a detailed analysis of everything you need to know about the galvanized iron wire sizes, making the selection process effortless for you.


I. Introduction

Brief overview of galvanized iron wire sizes

The sizes of galvanized iron wire typically refer to its thickness, not length. The thickness of galvanized iron wire also called the wire diameter of galvanized iron wire, which represents the sum of the thickness of the high quality iron wire(Q195/Q235) material and the thickness of the zinc protection layer on the surface of the low carbon steel wire.

The wire diameter of galvanized iron wire is typically indicated by gauge or millimeters.


II. Understanding Galvanized Iron Wire Gauges

A. Explanation of galvanized iron wire gauge measurement system

Currently, the international community commonly uses AWG (American Wire Gauge), BWG (Brown & Sharpe Gauge), and SWG (Standard Wire Gauge) to indicate the wire diameter of galvanized iron wire.

For example,the #16 in AWG means 1.29mm,in BWG means 1.65mm,in SWG means 1.63mm.

The commonality among these three standards is that the larger the number of guage, the smaller the wire diameter of the galvanized iron wire it represents.

B. Galvanized iron wire gauge to mm

Because various countries or regions employ different appellation for the wire diameter of galvanized iron (GI) wire, it's important to note these diffrences. For instance, South Africa commonly expresses the wire diameter of galvanized iron wire in millimeters, while Dubai typically uses gauge to denote the galvanized iron wire diameter. Consequently, comprehending the conversion between different gauges and millimeters becomes essential.

So, how is the conversion between gauge and millimeters achieved?

For example:

10 swg galvanzied iron wire diameter is 3.25mm. 8 swg galvanized iron wire to mm is 4.06mm.

10 bwg galvanized iron wire in mm is 3.40mm. 12 bwg gauge galvanized iron wire diameter is 2.77mm.

10 awg galvanized iron wire diameter is 2.59mm. 8 awg gauge galvanized iron wire diameter to mm is 3.25mm.

For other specific galvanized iron wire diameter conversions, you can refer to the table above.

C. Importance of selecting the right gauge for specific projects

As the gauge number of galvanized iron wire decreases, the galvanzied iron wire diameter increases, resulting in higher strength, greater load-bearing capacity and less susceptibility to bending.

Conversely, galvanized iron wire with the smaller wire diameter is more easily bent, but it has a lower load-bearing capacity.

Therefore, people should choose galvanized iron wire according to their own needs. For instance, smaller wire diameter galvanized iron wire is suitable for securing plant vines, while the larger wire diameter and higher strength galvanized iron wire is needed if it's intended for rebar tying in construction.

From this, we can see that the main factors affecting the choice of galvanized iron wire are whether its load-bearing capacity and flexibility meet your own needs.

The most common uses for galvanized iron wire are as GI tie wires in construction and agriculture or, after processes such as weaving or welding, to make products like galvanized wire mesh fence or galvanized wire hangers. So, what size of galvanized iron wire is suitable for making galvanized wire mesh fence, and what size is appropriate for use as galvanized iron binding wire?Please read on.


III. Application-Specific Considerations

A. Construction rebar tie wire

The main use of galvanized iron wire in the construction projects is used as the rabar tie wire.The types of galvanized iron wire are straight cut galvanized iron wire,coil galvanized iron wire,loop galvanized ties and u type galvanized iron wire.

In construction projects, galvanized iron rebar tie wire typically ranges in diameter from 16 to 21 gauge, that easy to bend while maintaining good strength, making the galvanized iron binding wire capable of securing heavy items such as reinforcing bars.

B. Agricultural uses 

There are two main uses of galvanized iron wire in agriculture.

►The thinner gauge galvanized iron wire is more flexible and less likely to damage plants, making the galvanized iron wire suitable for securing plants to grow in the specific direction.

Larger wire diameter galvanized iron wire is used to secure fences or trellises. For instance, galvanized vineyard wire can be used to support grape vines or trellises.

►Another application of galvanized iron wire in the agricultural tasks is as galvanized iron tie wire for baling hay or other crops.

The wire diameter of galvanized iron (GI) wire used for agriculture typically ranges from 9 gauge to 16 gauge.

C. Wire mesh fencing and hanger

►Galvanized iron wire can provide corrosion resistance and good strength, making the galvanized iron wire suitable for outdoor use.Such as fencing for farms or cages for raising poultry.

The manufacturing process of galvanized iron wire mesh fence are typically weaving or welding.

The wire diameter of galvanized iron wire used for making galvanized wire mesh fence is usually range from 12 guage to 24 gauge.

►The clothes hangers we commonly use in our daily lives are also mostly made from galvanized iron wire. Galvanized iron wire hangers have better load-bearing capacity than plastic hangers and are rust and corrosion resistant, making the galvanized iron wire hangers very suitable for outdoor clothes drying.

The galvanized iron wire hangers' wire diameter is range from bwg 11 gauge to bwg 20 gauge.


IV. Conclusion 

The strength and flexibility of galvanized iron wire vary with the galvanized iron wire diameter. For applications like baling hay, the smaller wire diameter, more easily bendable galvanized iron wire is quite suitable. However, for constructing galvanized iron wire fences or bundling rebar in the building projects, the stronger, larger wire diameter galvanized iron wire is needed.
