The Fence Post

When thinking about installing fencing, you should first consider the environment in which it will be placed.

• Is it near the coast?
• Is it exposed to extreme changes in temperature?
• Will it be located in a wet or humid environment?
• Will it be in close proximity to corrosive chemicals, etc.?

Identifying these factors will help you determine the best type of fence product and coating for your needs.

GBW - Galvanized Before Weld

Let’s start with the basic low-cost GBW welded wire fence. This product is available in a wide variety of styles and sizes for lots of different applications. This is what most “Big Box” stores sell.

• The good news? It is inexpensive.
• The bad news? It has a shorter life because it is more susceptible to rust and corrosion.
• The reason? The wire is welded before it is galvanized. The welding process can “burn-off” the zinc on the weld points. This makes the wire more vulnerable to rust and corrosion.

The initial strength and gauge of the GBW wire are the same as GAW and VC. But the finish is not nearly as durable resulting in a shorter usable lifespan.

If price rather than quality is the most important factor, then GBW might be a good choice for you.

GAW - Galvanized After Weld

GAW welded wire is dipped in molten zinc after being welded or woven. The wire is fully encased in zinc for greater protection and longer life. This is especially important if the fence is to be installed in coastal areas, and if rust and corrosion are primary concerns.

• The good news? Extended lifetime
• The bad news? It is slightly more expensive than generic GBW meshes.
• The reason? After the wire mesh is welded or woven, the finished product is drawn through a bath of molten zinc. The wires are thoroughly galvanized. And most importantly the welded joints are completely covered and protected from the elements. Moisture, which tends to collect in these areas, is prevented from contacting the underlying wire.

If quality and long life are the most important factors in how you will make your decision, GAW is a great choice. The thick galvanization present on the wires adds years of life to the fence. GAW fencing materials will long outlast commonly available GBW products. You have to look harder to find GAW wire fencing materials, but your search will be rewarded with years of service. Avoid the needless expense and hassle of frequent replacement. Buy a product that will last!

VC - Vinyl Coated

VC welded wire has been coated with a layer of PVC after the mesh is welded up. The vinyl covers the mesh and provides strong protection against the element.

• The good news? Extended lifetime and attractive appearance
• The "bad" news? It can be more expensive than GBW and GAW products.
• The reason? The addition of the PVC coating adds an impervious barrier, protecting the wire from Mother Nature's harshest elements. The protected wire will not rust as quickly.

If you want a product that is not only attractive but is also able to withstand environmental stressors, VC welded wire mesh is the perfect one to use. Black mesh becomes virtually invisible.

Note: It is very important to know what to look for when considering VC wire fencing materials. The best possible protection and longest life expectancy are offered by a product that is vinyl coated over GAW wire mesh. You will have rugged double protection. You will not be disappointed.

SS - Stainless Steel

SS welded wire fences provide the greatest level of protection and long life in any environment. The product is more expensive up front but can save lots of money and time in the long run because the fence will not need to be repaired or replaced. Stainless Steel wire needs no additional coating because it will last for years and years in practically any environment.

• The good news? Very long life with little maintenance required
• The "bad" news? Yep, It's pricier.
• The reason? Stainless Steel is a more expensive material. But in certain applications, its longevity will ultimately prove less expensive.

Did you know there are a great many varieties of wire mesh fencing materials available to you?

The Desert Tortoise: Endangered

You may not realize it, but the Desert Tortoise is struggling to survive after millions of years of life on earth. The desert tortoise in the Mojave Desert (north and west of the Colorado River) was federally listed under emergency provisions of the Endangered Species Act of 1973 as endangered on August 4, 1989 and permanently listed as a threatened species on April 2, 1990. The tortoise was listed because of direct losses and threats to tortoise populations and habitat.

The desert tortoise is the largest reptile and the only wild land tortoise found in southern Nevada. It also exists in western California, southwestern Utah, western Arizona, and northwestern Mexico. A tortoise will live in the same general area of less than one square mile during its lifespan of 50-100 years. They reach 10 to 14 inches in length and are soil colored. Because of their color and shape, they can be very difficult to see.

Awareness

To help protect tortoises from getting on roads and highways, Tortoise Exclusion Fence, also referred to as Turtle Fence, is being installed throughout their habitat. Many construction projects are now even required to have an on-site biologist conduct a thorough survey of the job site and flag all burrows prior to construction. Construction crews are also required to complete a desert tortoise education program.

Tortoise exclusion fence is required and specified in many bids where highways and roads or solar fields will be constructed in tortoise habitats. It is installed to keep the tortoises out of harm's way on highways and in solar fields.     

Exclusion Fencing

Tortoise Exclusion Fence is designed specifically for preventing tortoises from gaining access to highways and roads and any other designated areas. It is made of galvanized welded wire which has a mesh opening of 1” horizontal by 2” vertical and is 36” wide. The fence is constructed of 16 gauge or heavier wire and can be GAW (Galvanized After Weld), GBW (Galvanized Before Weld) or VC (Vinyl Coated) depending upon the specifications required.

Methods

The fence material is buried a minimum of 12 inches below the natural level of the ground to prevent tortoises from burrowing underneath. This leaves 22-24 inches above the ground. In situations where burying the fence is not practical because of the rocky substrate, the fence material should be bent at a 90-degree angle to produce a lower section approximately 14 inches wide which will be placed parallel to, and in direct contact with, the ground surface. It is installed using 5 to 6-foot steel T-posts, hog rings, and smooth or barbed livestock wire. Distances between the T-posts should not exceed 10 feet unless the desert tortoise fence is being attached to an existing right-of-way fence that has larger spaces between posts. See the official US Department of Fish and Wildlife specifications for desert tortoise fencing.

Installing the proper tortoise exclusion fence will protect the desert tortoises from possible extinction while protecting you from fines and possible imprisonment.

Let’s all work together to save the tortoises!

Delaying Rust and Corrosion

Vinyl Coated (VC) welded wire mesh has been coated with a layer of PVC after the mesh has been welded. This is significant because the vinyl covers the mesh and provides protection against the elements. Rust and corrosion are delayed much longer than with an unprotected Galvanized Before (GBW) mesh.

• The good news - extended lifetime and attractive appearance
• The bad news - more expensive than non-vinyl coated material
• The reason -  addition of PVC coating provides an impervious barrier, protecting the underlying wire from the environment. The protected wire will not rust as quickly.

Looking for a product that is not only attractive but is also able to withstand environmental stresses? VC wire mesh is the perfect one to use!

Wire Gauges, Mesh Openings

It is very important to not only know what to look for, but also what is available when considering VC welded wire fencing materials. There are many choices - something ideal for any project you have in mind.

Wire Gauges: 23, 19, 16, 14, 12-1/2, 11, and 10-1/2

Mesh Sizes: 1/4" x 1/4", 1/2" x 1/2,", 1/2" x 1", 1" x 1", 1" x 2", 1-1/2" x 1-1/2", 1-1/2" x 4", 2" x 2", 2" x 3", 3" x 2", 2" x 4", 3" x 3"

Beware of Inferior Products

Higher quality vinyl coated fencing material costs more than cheaper inferior products. You get what you pay for. People are often fooled by false economy. When you consider the time, hassle and additional expense of premature replacement of your fence, it is clear that a higher initial investment can ultimately save you money.

It is safe to say that the best possible protection and longest life expectancy is offered by a product that is vinyl coated over GAW (Galvanized After Weld) wire mesh. You have rugged double protection with both the zinc and the PVC coatings. While difficult and probably impossible to find in big box retail stores, this mesh is well worth the time and effort of a search. You will not be disappointed. Many, but not all specifications are available with GAW core wires.

Understanding Levels of Quality

If you are concerned with quality, be aware that there are different levels of quality available.

The lowest quality products are those that have coating over plain steel, non-galvanized wire. There is no protective layer of zinc on the wire. In this case, the coating is virtually worthless. Usually, the PVC is not tightly bonded to the underlying wire. It can often be easily scraped off the wire with nothing more than a fingernail. Moisture migrates in between the vinyl and the wire and the mesh rusts from the inside out. It will look fine on the outside when you load it in your shopping cart. But when the wire disintegrates and falls apart you have a mess. Hopefully, this never happens to you.

The next best quality of vinyl coated welded wire meshes are those that have GBW (Galvanized Before Weld) wire under the PVC. The galvanizing protects the wire. But the intersecting areas of the mesh where the welds occur are not well protected. During the welding process, the zinc is burnt away. Although zinc will "flow back" in an attempt to recover the areas, they are the first areas to decay and corrode. It is important to check out how securely the vinyl is attached to the wire. It may or may not be tightly bonded. If you can peel it off with a fingernail, it probably will not last as long as fencing material with a superior coating.

As mentioned above, the best quality products are those with the following characteristics: 1) GAW wire mesh is underneath the PVC; 2) the vinyl is tightly bonded to the wire. The welded areas are thoroughly protected and the vinyl is not easily scraped off the wire. The vinyl coated welded wire fencing material with these characteristics are what you need if you want years of trouble-free service. It is worth the effort required to find them.

A Test for You to Do

The only sure way, though not always possible or recommended, is to try scraping off a small section of vinyl. If you can start it with your fingernail and slide the coating along the wire (see picture below) you know the coating is not tightly bonded. If the coating resists peeling and requires a sharp blade to scrape it off, you will know the coating is tightly bonded.

If the underlying wire is dark gray or black, this means there is plain steel beneath the coating. Make sure this is the product you really want to buy.

If the wire is bright and shiny it is galvanized. Check out the intersecting weld areas. If you see burns and blackened wire it is GBW. This is an example of non-bonded vinyl coating over GBW wire:

Clumping that You Want!

If the wire is bright and shiny and the welded areas have clumps of zinc around them, the mesh has been galvanized after. This is what GAW mesh looks like:

Keep in mind that you do have choices and do not have to settle for the products that are right in front of you, especially if they are (or might be) inferior. Be aware that the person working in the store probably knows less than you do about the differences in products and why a different item may be more suited to your needs. Consulting with the experts at Louis Page is a necessary first step.

Is it Time for an Apron Fence?

Although the name "apron fence" might make this product sound like kitchen garb, it is actually a versatile and uniquely designed fence that is ideal for a host of different applications. 

No Trench

Since there is no need to dig a trench (a time bandit hassle), installation is quick and easy. Simply place the apron on the ground and cover it with soil or grass for a neater appearance. Vegetation will grow up through the mesh, securing the fence to the ground.

Perfect for Beagles etc.

Apron fence is ideal for beagle training pens, running pens, kennels, as well as game bird pens and chicken pens. Great for a garden fence because it protects the garden from hungry wildlife looking for a free and tasty meal!

Choose Galvanized or Vinyl-Coated

Apron fence is made of 17 gauge galvanized steel 1½” hex wire, making it more than twice as strong as standard 20 gauge 1” hex chicken wire. This greater strength and durability provide longer life. Made in the USA, it is available in two sizes – 60” (48” fence height, 12" apron) and 72” (60” fence height, 12" apron) and in galvanized or vinyl-coated finish.

Long-Lasting, Flexible, and Attractive

The vinyl coating is bonded to the wire and is UV stabilized for long life. The black vinyl coating is more attractive and blends into the background, becoming nearly invisible; plus, you can easily see what is inside the fence, enhancing the perspective of your garden. Paying more upfront for vinyl coating will save money and time in the long run because it will last years longer than the galvanized, and will eliminate the expense and hassle of replacing the fence.

Whether your objective is keeping animals in or keeping them out, Apron Fence will exceed expectations!

A Skunk Under My Shed 

The Fluffy Shadow 

I have to think twice before taking the garbage out at night or going to find something in the shed after dark. When I go from car to house or house to car after dark, I move quickly with eyes scanning the ground for a fluffy shadow or set of eyes twinkling in the moonlight. My dwelling is terrorized by a skunk that wages a putrid form of guerrilla warfare against my household. It has made its home under our shed and I am loath to engage it in battle. It has to go. We can’t stand the thought of more summer evenings spoiled by the threat of an altercation with these hostiles. The question is: how does one get rid of a skunk?

Methods for Extraction

Modern life offers a lot of very easy solutions to problems that confounded earlier generations. Unfortunately, there is no “easy button” for skunk removal. Unless I am willing to damage the shed (what I’m calling the tip and run method), the animal (poison), or both (flooding/burning) I don’t know how to avoid the physical act of removing the animal. There are some tips on how to get rid of them, but the ones that don’t risk an encounter with the skunk, seem not to work. For example, I read that putting a dirty sock by their entrance would make them move their home. This is untrue. I put a post-basketball sock out there and if this sock wasn’t dirty enough, we might be better off with the skunks than a dirtier sock. I waited a few days hoping that the skunk's repeated encounters with the sock would send it packing, but alas, the skunk remains.

Chatting with a Professional

As may already be apparent from this post, I have an intense fear of being sprayed by a skunk. Generally, I like do-it-yourself projects, but I think for the removal phase of this project I will have to turn to a professional. I spoke to a Louis Page customer, Erik from Needham/Woburn Pest Control, about how to keep the critters out from under the shed once they are extracted. He recommended the following labor-intense, yet straightforward solution.         

1. Dig a trench around the shed 12” deep and 12”-18” wide extending away from the base of the shed.
2. Using ½" x ½" welded wire mesh, 36” wide, staple the top edge to the base of the shed with galvanized staples.
3. Lay the remaining 30 or so inches into the trench to cover 12” inches down and 18” out.
4. Backfill the trench and voilà! Skunk proof!

Since the mesh will be underground, I’ll need to be sure that it is resistant to rust and corrosion. Galvanized after weld offers good protection, but black vinyl coated mesh would be even better and the small amount of exposed wire mesh around the base of the shed will look much better over time if it does not rust. Also, the black color will be virtually invisible. This is really not something I want to do twice.

That’s the plan I think. Onward and upward. And certainly, your ideas are always appreciated!
