Ever wonder how barbed wire became such an important invention? You probably don’t give much thought to the type of fencing used for containing livestock or securing property. Barbed wire, with its sharp metal barbs, revolutionized fencing in Nigeria. Before barbed wire, fencing options were limited to wood and smooth wire, which were expensive, required frequent repairs, and didn’t effectively contain livestock.
Once barbed wire was introduced, it spread rapidly across the globe, forever changing the landscape. Keep reading to learn about the features, types, and advantages of this simple but highly impactful invention.
What Is Barbed Wire?
Barbed wire, also known as barb wire, is a type of steel fencing wire with sharp edges or points arranged at intervals along the strand. The barbs are the sharp points that stick out from the wire. Barbed wire fences are inexpensive, effective barriers used to confine livestock and secure property.
Its primary use is in the construction of low-cost fences, but it is also used as a security precaution atop walls encircling property. Attempting to pass through or over barbed wire will cause discomfort and possibly harm. Only fence posts, wire, and attaching methods such as staples are required for barbed wire fencing. It is simple to build and quick to assemble, even for inexperienced workers.
A Brief History of Barbed Wire
Around 2,000 years ago, ordinary wire was created. In 1873, an American farmer named Joseph Glidden invented barbed wire, which is still in use today. The first patents on the barbed wire were issued in the United States in 1867, but it wasn’t until 1874, when Joseph Farwell Glidden devised a workable machine for its production, that the concept gained traction. However, primitive forms were created by other Americans earlier; the first was most likely L B Smith of Ohio in 1867.
Features, Types, & Advantages Of Barbed Wires
Barbed wire comes in different thicknesses called “gauges”, the lower the gauge, the thicker the wire. For most farm fencing, a 12.5 to 15.5 gauge wire works well. The barbs also come in different sizes, typically 1 to 2 inches in length. More barbs mean better deterrence, but they’re also more dangerous to install and maintain. While the barbs can cause injury, barbed wire remains an affordable and effective fencing option if properly installed and handled.
Key Features of Barbed Wire
Barbed wire has sharp barbs or points that are twisted and spaced at intervals along the wire. These barbs deter animals and people from passing through the fence.
The key features of barbed wire, like the sharp barbs, galvanized wire, barb spacing, and wire gage, allow it to effectively contain livestock and deter unwanted intrusions. With some maintenance, barbed wire fencing can last 15-20 years or more, making it a durable and cost-effective fencing option.
Types of Barbed Wire
While it is no longer as necessary as it once was, barbed wire is still a useful security technique. However, not all barbed wire is the same. There are various types, each with unique strengths and applications. By understanding these distinctions and how to use them, you can ensure that your barbed wire performs as intended.
Twisted Barbed Wire
Two strands of wire twisted together with barbs attached. Typically used for internal fencing. There are two main types of twisted barbed wire, which are:
Conventional twist barbed wire
Conventional twist barbed wire features two strands of wire twisted together with barbs attached. The barbs are spaced evenly along the wire, typically every 3 to 5 inches. This design allows the barbs to grip into anything that contacts the wire, making it difficult to get past.
Reverse twist barbed wire
Reverse twist barbed wire is made of two strands twisted in opposite directions. The reverse twisting causes the barbs to stand out at different angles, allowing for maximum entanglement. The barbs also grip better in both directions. This makes reverse twist wire more effective at deterring intruders.
Material-Based Barbed Wire
When it comes to barbed wire, you have options based on the material used.
PVC Coated Barbed Wire
PVC-coated barbed wire is a type of fencing material created by coating the barbed wire with Polyvinyl chloride. The PVC coating protects the wire from dirt, chemicals, and damaging UV radiation. This increases the wire’s durability and resistance to corrosion and degradation. The wire is coated with either low-carbon steel wire or galvanized steel. It is frequently utilized in industrial and commercial settings. It is also used for decorative fencing because it comes in a variety of hues, such as green, yellow, grey, red, and so on.
Galvanized Barbed Wire
Galvanized barbed wire is also known as zinc-coated steel wire since it is manufactured by mixing steel wire with a zinc coating. This is known as galvanization. The zinc prevents rusting and corrosion, making it perfect for use in outdoor applications. This makes the wire last longer and requires less maintenance than uncoated wire. It’s low-maintenance but can be pricey.
Concertina Wire
The concertina wire is made up of interlaced strands of barbed wire that are coiled up into a coil. When the coil is unrolled, the strands of barbed wire fan out and form a sharp, spiky barrier. Concertina wire is commonly employed in military and security applications because it is easy to deploy and effective at discouraging and slowing down attackers. The wire is composed of a succession of razor-sharp barbs that are closely spaced, making it impossible to pass through without being cut.
Stainless Steel Barbed Wire
Stainless steel wire is one of the most adaptable materials available today. Stainless steel wire is a good alternative for situations requiring high corrosion resistance. This wire is composed of iron, chromium, and other alloying elements, which provide it with high resistance to rust and other forms of degradation. Furthermore, stainless steel wire is strong and long-lasting, making it suitable for a wide range of applications.
Zinc Aluminum Alloy Coated Steel Wire
This wire has a zinc-aluminum alloy coating over steel wire. It contains 5% aluminum-zinc alloy wire, known as Galfan wire, and 10% aluminum-zinc alloy wire, depending on the composition. This wire is used for a variety of purposes, including electrical conductors, structural support, and protective barriers. The alloy coating protects the wire from corrosion and rust while maintaining strength and durability. This type of wire is also very cost-effective.
Stirred Barbed Wire
It is made out of a wire that is coiled around a metal rod and then covered with sharp and pointy barbs. Barbs are often constructed of steel or iron and are intended to snag on clothing or skin. When the wire is moved, the barbs shift and sharpen, making them more hazardous. The barbs are uniformly placed along the length of the wire. Stirred barbed wire can be found in a variety of places, including prisons, military stations, and industrial plants.
High Tensile Steel Barbed Wire
High Tensile Steel Barbed Wire Is made of high-tensile steel with a thin layer of zinc coating. The wire has a greater carbon content of roughly 0.28%, giving it a high tensile strength. This increases the wire’s resistance to breaking and allows it to endure the weight of animals or people leaning or climbing on it.
Strand-Based Barbed Wire
When choosing barbed wire, you have a few options based on the number of strands.
Single Strand Barbed Wire
2-point barbed wire is another name for single-strand barbed wire. It consists of a single barb twisted on a strand or line wire to generate two pointed ends. This wire is typically used for agricultural fencing. The barbed wire is made up of sharp points or barbs spaced at regular intervals along a wire.
Double Strand Barbed Wire
Double barbed wire is also known as 4-point barbed wire. It is made up of two barbed wires twisted together on a line wire, resulting in four-pointed ends. Farms, ranches, and other rural locations may have double-barbed wire. Double barb wires provide additional protection and dissuade trespassers due to their more pointed edges.
Barbed Wire Based on the Number of Points
When it comes to barbed wire, the number of points refers to the number of barbs attached to the wire. The more points, the more effective the barbed wire is at keeping things in or out.
Single Barb Wire
The most basic is the single barb wire, which has one barb attached at intervals along the wire. While inexpensive, it provides only minimal security and protection. The barbs are easy to spread apart, allowing passage through the fence.
Double Barb Wire
Double barb wire improves on single barb wire by attaching two barbs at intervals along the wire. The double barbs are more difficult to spread apart and provide better protection from trespassing animals and humans. The closely spaced barbs also make the wire harder to cut. Double barb wire is a good, cost-effective choice for most basic fencing needs.
Benefits and Advantages of Using Barbed Wire Fencing
Here are some of the benefits and advantages of using Barbed Wire Fencing
Safety
Barbed wire fencing helps keep livestock and people safe by clearly marking boundaries. The sharp barbs deter animals and humans from crossing the fence.
Cost Effective
Barbed wire is an affordable fencing option, especially for large areas. The wire itself is inexpensive and easy to install without requiring specialized equipment or skills.
Easy to install
With the right equipment, a barbed wire fence is very simple to install. If you enjoy DIY projects and have all of the necessary tools, you won’t need to hire a professional to assist you. However, if you have a large property, you may need to pay someone to install it because it may need some preparation.
Low Maintenance
Once installed, barbed wire requires little upkeep. It does not deteriorate or weaken quickly and typically only needs occasional repairs or replacement of damaged sections. The galvanized wire is weather-resistant and can last for many years.
Versatile
Barbed Wire is adaptable enough to be utilized in a wide range of industries, including residential properties, industrial, commercial, sports, transportation, agricultural fields, and so on. Furthermore, you may easily personalize your barbed wire fencing based on the length, height, and design that you desire.
Safety and Injuries
Safety should always come first when handling barbed wire. The sharp barbs can easily cause injuries if proper precautions aren’t taken.
Handling
When unrolling and stretching barbed wire, wear thick protective gloves, long sleeves, and eye protection. The barbs can easily puncture skin and scratch eyes. Use wire stretchers or fencing pliers instead of bare hands when pulling taut.
Installation
Exercise caution when installing barbed wire fencing. The wire tends to coil, so it slowly unwinds in a controlled manner. Have an extra set of hands to help guide the wire and maintain tension. Wear heavy-duty work gloves, boots, and long sleeves.
Removal
Removing old barbed wire also requires safety measures. The barbs may have become dull or rusty over time but can still cause injury. Wear protective gear and use fencing pliers to grip the wire. Carefully unwind in a slow, controlled motion. Roll up the used wire tightly to avoid loose barbs.
First Aid
In the event of an injury from barbed wire, thoroughly clean the wound to avoid infection. Apply pressure to control bleeding and bandage. Seek medical attention for serious or infected injuries. Keep a well-stocked first aid kit on hand, especially when installing or removing barbed wire fencing.
How to Choose the Right Barbed Wire for Your Needs
When choosing barbed wire, consider the following factors:
Thickness
The thickness or gauge of the wire determines how much tension it can withstand. For large animals like cattle, choose a heavier 12.5 to 15.5 gage. For smaller areas or less rugged terrain, 14 to 16 gage may suffice. The lower the gauge, the thicker the wire.
Number of Strands
More strands provide greater security but are more expensive. For most needs, 4 to 6 strands of wire should be adequate. High-security applications may require 8 strands or a double row of fencing.
Barbed Wire Style
There are several barbed wire styles:
- Plain wire has no barbs, only strands. Best for visual barriers or lightweight security.
- Barbed wire has sharp barbs for deterring animals. Popular for securing livestock.
- Razor wire has sharp razor blades and is extremely effective but also dangerous. Primarily used in high-security commercial and industrial applications.
Spacing
The spacing between strands and barbs determines how much the wire can deter different animals. Closer spacing, around 6 inches, is best for small animals. Wider 9 to 12-inch spacing suits most livestock fencing needs.
Cost
Barbed wire pricing depends on the factors above, as well as the total linear feet required for your fence line. Be prepared to pay between 18,000 naira to 25,000 for a one-foot roll of Barbed Wire in Nigeria.
In summary, choosing the right barbed wire comes down to assessing your specific needs, property, and budget in order to determine the best combination of wire thickness, strands, barbs, spacing, and overall cost for your situation. With some thought, you’ll be well on your way to finding the perfect fencing solution.
How Long Does Barbed Wire Last?
Barbed wire, if properly installed and maintained, can last 15-30 years. The exact lifespan depends on the gauge of wire used as well as environmental factors like weather and soil conditions. Thicker wire gages, like 12.5 or 15.5, tend to last longer. Galvanized wire also has greater longevity since the zinc coating helps prevent rust.
What is the Best Type of Barbed Wire?
The best type of barbed wire for your needs depends on the purpose. For livestock, a thicker gauge wire with closer strand spacing is best. For property perimeter fencing, a lighter high-tensile wire may suffice. You’ll also want to consider how much pressure the fence will receive to determine the number of strands and barb style. In the end, the best-barbed wire is the one that effectively contains what you need to contain.
Conclusion
So there you have it, an overview of barbed wire and why it’s still so widely used. Barbed wire isn’t going anywhere anytime soon. Its durability, effectiveness, and low cost mean it will likely remain a fixture in houses, farms, and ranches for generations to come. While not the prettiest or most charming of fencing options, barbed wire does its job and does it well.
