High Tensile Wire: Impressive Benefits

• Lighter in weight, but stronger (thanks to its tensile strength)
• Won't sag; stays put
• Less need for tensioning 
• Smaller gauge/diameter of the wire is more efficient (especially compared to heavier low carbon wire)
• Though stiffer, ultimately, installation is easier because it doesn't have to be stretched as hard as low tensile wire; tension it and it's ready to go
• Fewer posts are needed thanks to its strength and vertical stay wires
• Springs back with animal impacts; it has give but retains its shape

High Tensile Wire: Thinner is Stronger

As you'll see toward the end of this video, four wires with a similar gauge have very different breaking strength based on the carbon content:

High Tensile Highlights 

A fixed knot fence is effective on challenging terrain and remains rigid between posts. The .64% carbon content steel wire used in a fixed knot fence is noticeably thinner. However, strong as it is, this high tensile wire would be lost without a protective coating. This is why the requisite Class 3 galvanization, with its anti-corrosion properties, is added to offset steel's natural disintegration which enhances its cost-efficiency by delaying repair and replacement. High tensile wire is the choice when a long-term fence solution is required as it remains a strong, versatile answer to a variety of fencing needs. 

Low Carbon Drawbacks

Now, low carbon steel wire is easy to work with as well, (also known as mild steel) but it is prone to sagging, stretching, and breaking more easily than high carbon-content steel wire. The carbon content for low tensile wire is roughly .28%; while this type of fence is common, it remains a shorter-term answer.

Installation

Here's a comprehensive how-to from Bekaert that details the installation of a fixed knot fence:

Stubborn--yes, but also strong and smart

Barnyard or backyard, goats may be a source of comic relief or the creators of mayhem. So much depends on the enclosure you provide for your herd. Goats interact with fencing and will test its limits. Your herd of goats will find a fence's vulnerability and capitalize on it for their own exploring and ravenous ends. 

To begin with, a 4 foot high tensile woven wire fence with 4" x 4" openings is the rule. Goats are strong and smart and your fence has to be as well. Tough and flexible woven 12.5 gauge wire with strong stiff stay knots is imperative. This combination of factors will stand up to the roughhousing that goats bring to the party.

About those terms--

• Woven Wire--A woven wire fence's linked yet loose structure allows for a large amount of bend, twist, and pull without breaking--a perfect design if you have livestock to contain
• Woven Wire--also makes for secure mesh, strong enough to hold together well when impacted by a demanding goat; plus, it adapts to variable terrain                                                                                        
• 12.5 Gauge--a thickness of wire with a minimum of 1,350 pounds breaking strength, plenty strong for your goats                                                                                                                                           
• High Tensile--means higher carbon steel wire, roughly twice the strength of low carbon wire yet lighter due to the higher grade of steel, the payoff being easier handling. Safer than barbed wire for your goats and can be electrified 
• Standard Class 3 galvanizing--protects the wire and extends its life; with proper maintenance, it can last up to 40 years    
• 4" x 4" Openings--goats can't get their heads and horns through, avoiding injury; it's smooth wire--again, reducing injuries                                                                                        
• S knot--(also known as Square Deal) this knot is used in making non-climb 4" x 4" mesh sheep and goat fence; the S knot prevents the fence from buckling or sagging; it also provides extra vertical strength and rigidity while at the same time allowing flexibility; these knots add to the fence's adaptability to hilly terrain; one-piece vertical stay wires, attached to line wires--with a crimp, prevent slippage

Don't Underestimate Your Goat

Add an extra strand of electric fence wire at the top of the fence to ensure safety, especially for more ambitious goats. Yet, no matter what system is in place when keeping goats: vigilance is required. Be assured, a break or defect in a fence and your goats will take advantage of it--down the street before you know it. Hello, neighbors. Straying goats will munch a rose bush over a clump of grass.

When goats are limited to a grassy enclosure, the incidence of worms and parasites goes up. They are known as browsers in their style of feeding--leafy fodder above the ground is of particular interest and they will use a fence to find ways to get at bushy shrubs and the lower growth of trees--or happily climb trees. If you've got a goat that makes a practice of finding new and creative ways of escaping, it may be time to enhance your enclosure for Ms. or Mr. Gruff, upgrading your existing fence. A rebellious goat will readily tutor other goats in your herd with its pillaging tactics.

The Ingenuity of a Goat!  Wait for it...

Check with the Town

If you're desiring a backyard goat, remember that cities and towns may have size and number limits of your herd. And consider your neighbors as they can be noisy as well as hungry. You must have space--you cannot "share" your yard with a goat: your yard won't exist after a goat has its way with it. As omnivorous as they seem, they will not eat what they've peed on so their fodder must be kept off the ground in a raised feeder. 

Spring Shedding

Seems to be that shedding is going to be one of the stressors on your fence. Shedding? Yes, this is why a woven wire fence comes in handy; it flexes with the strains of a goat, using it to rub off its warm winter undercoat that comes off each spring. You might give your goats a good brushing to help the process along and prevent some wear and tear on your fence. 

Consider Predators

Your goat may be wily, but it is also vulnerable to attack. “Coyotes are very good at killing sheep and goats. They will eat anything from newborns to adult animals. They are a threat year-round,” says Reid Redden, Texas A&M extension sheep and goats expert. Other trouble makers are:

• dogs
• bobcats
• eagles
• vultures
• mountain lions
  

He confirms there are various trapping methods--but for success, there's nothing like a good fence.

A Few Facts:

• First and foremost--goats are social animals and being isolated is stressful for them
• They walk immediately after being born and are weaned around 3 months
• Birth occurs in spring, after 5-6 months gestation, producing 1 or 2 kids
• A male goat is known as a billy or a buck; if castrated, they are called wethers
• Females are does or nannies; they are generally ready to breed once they have reached 80 lbs.
• The lifespan of a domesticated goat is generally 12-18 years, varying with the breed

Protecting people from lava flows and from themselves.

There are some fencing products on their way to Hawaii. It seems some physical barriers are required to offset the lava-play aficionados and looky-loos that are putting themselves at peril. For us at home, observing the mesmerizing lava flows from your screen of choice is a popular pastime, quite understandably. However, far from these screens is the tough job of predicting the actions of people who are curious or foolhardy enough to want to get close to the volcanic activity. Louis Page has been called in to assist with the fence and mesh needed to curb these adventurous and possibly harebrained scofflaws. Remember that vinyl coated high tensile wire is the fence of choice for longevity and strength.  

Over-reacting? Nope. 

The dangers are numerous:

• Those fascinating sea water explosions of boiling water and steam require onlookers to be at least a 1/4 of a mile away for safety. That steam is not just water vapor! 
• Methane gas is created when vegetation is inundated without oxygen, exploding up to 100 yards ahead of the lava flow.
• The flows emit fumes that contain glass particles, sulfuric acid, and hydrochloric acid--no walking or standing in these toxic clouds.
• And some folks are enticed onto the new land created by the lava hitting the ocean--called benches--which are very unstable and prone to collapse.

Tourists and Hawaiian residents, observing bursts of gas and flame from the streams of lava, are being arrested for walking on hardened igneous rock and trespassing citations are handed out as people avoid barricades to take pictures, being caught going through areas with toxic gases.

The Phenomenon of Pele's Hair

And if the above list wasn't enough, there are the fine flaxen tresses of Pele. Named for the Hawaiian goddess of volcanoes, droplets of cooling lava are stretched up to six feet in the wind and should not be touched as it is actually volcanic fiberglass that can be very sharp and penetrate the skin. Here is a quick video to illustrate this phenomenon:

Fines

Entering certain zones bring a $5000 penalty and a year in jail. These reflect fines and punishments increased recently by the Department of Land and Natural Resources.  

Is there a type of fence that you need to manage or direct pedestrians? Louis Page can assist you in finding just the right fence for your situation.

Containment or Exclusion?

There are many different styles of woven wire fence that can be successfully used in zoo displays. These wire fencing products can also be put to use around the home, farm and public areas such as parks and recreational areas. Think of these fences when you have any situation where animals need to be contained or excluded.

Double-Wattled Cassowary & 2" x 4" woven wire mesh - Birmingham Zoo

2" x 4" openings, 12.5 gauge mesh -- Large Birds, Dogs, Horses, and Zebras

Woven 2" x 4" mesh is made with heavier 10 gauge selvage wires running along the top and bottom edge of the fence. This gives the fencing greater strength. Strong 12.5 gauge wire makes up the balance. A third piece of 12.5 gauge wire forms a smooth stiff knot around the horizontal and one piece vertical wires securely holding them together. Knotted construction gives the fence some flexibility making it easier to install over uneven ground. Woven 2" x 4" mesh is available in three different finishes: Class 1 galvanized, Class 3 galvanized and Class 3 black. It can be used effectively with very large birds, other animals such as dogs, horses and zebras and any other animal that requires a strong fence. 

Woven 2" x 2" wire mesh fence on sides of display - Franklin Park Zoo

2" x 2" openings, 16 gauge mesh -- Birds and Small Animals

Made with the same knotted construction as the 2" x 4" fencing, this lighter weight woven wire fence is made using 14 gauge wires on top and bottom and 16 gauge wires for the filler. As with its heavier brother, the fencing has inherent flexibility. 2" x 2" mesh can be used with birds and other small animals - situations where a lighter fence will be effective.
