The Advantages of High Tensile Wire

• Are you thinking about using field fence to enclose your animals and property?
• Agricultural fencing is available in two types of wires: low carbon and high tensile. What's the difference?
• Is there an advantage to using one over the other?

Low Carbon Wire - easy to work with, but...

For years, traditional field and farm fence have been made using low carbon wire. Low carbon wire used in fencing is usually made from steel rod with a carbon content of approximately 0.10%. It is easy to work with but is prone to stretching and sagging. It requires regular maintenance and is weaker than high tensile wire.

High Tensile Wire - inherently Stronger

This wire has become very popular due to its advantages. It is made from steel rod with a carbon content of approximately 0.28%. Higher carbon content makes high tensile wire stronger. Its higher psi rating gives it a higher breaking strength. To get the same strength, you can use a lighter gauge high tensile wire in place of a heavier low carbon wire. You can complete your project at a lower cost.

• Lighter weight also means easier handling and installation. Fewer posts are required so you can increase the spacing between posts. If installed properly, high tensile fences require little maintenance. Re-tensioning is not necessary.

• During installation high tensile fencing requires less tension to make it tight. The wire is stiffer and will not stretch and sag. This characteristic gives it flexibility - it will give and bounce back when animals lean against it.

This video shows quite dramatically the differences between these two types of wire:

You have a collection of valuable birds you want to contain within a certain area. You want the birds to be safe from predatory birds from above. You want to cover a large area. You want a high ceiling or open roof. Installation needs to be as easy, safe, and as fast as possible. The material you use must be soft and flexible, enough so that the birds will not hurt themselves when they come in contact with the netting while they are in flight.

What can satisfy all these requirements?

Flight Pen Top Netting - long life and easy to use

Used by zoos, commercial game bird farms, animal rehabilitation, and backyard hobbyists. The multiple strands of woven black polypropylene provide protection for your birds. Here's a list of the benefits:

• Rolls are lightweight and easy to handle
• Support structure can be less robust, less expensive
• Large size rolls make it easier to cover large areas
• No need to make a patchwork of smaller rolls
• Flexibility makes top net softer - less chance of injuring yourself and your birds
• Available in a wide variety of roll sizes, weight, and mesh sizes
• UV resistant for long life
• Top net will not rust
• Mesh is resistant to mildew and rot

Do you have any birds that need safety and protection?

  

So That They Shift No More! 

Carting rocks around from one place to another can be a risky business. And yet, you need to get them from the source to the dealer and then ultimately to the job site.

Rocks Controlled

You pile them on a pallet, but how do you keep them from rolling around? How do you make sure they don't roll off the truck and smash onto a passing vehicle? How do you safely restrain them?

Secure Rocks Using Wire Mesh

Have peace of mind as you roll along. Be free from worry, knowing that your stones are securely wrapped in wire mesh. They will reach their destination without incident.

Wrapping Stone Pallets--Options

• Woven wire mesh - 20 gauge, 18 gauge, 16 gauge, 12½ gauge
• 1", 1½", 2" hexagonal mesh
• 2" x 2", 2" x 4" "square" mesh
• galvanized before, galvanized after and vinyl coated finish
• Welded wire mesh - 16 gauge, 14 gauge, 12½ gauge, 11 gauge, 10½ gauge
• mesh sizes: ½" x ½", ½" x 1", ½" x 2", ½" x 3", 1" x 1"
• mesh sizes: 1" x 2", 1½" x 1½", 2" x 2", 3" x 2", 1½" x 4", 2" x 4"
• galvanized before, galvanized after and vinyl coated finish

Secure Animals: Containment and 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.

 12.5 gauge, 2" x 4" mesh

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 on 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, zebras, and any other animal that requires a strong fence.

16 gauge, 2" x 2" mesh

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.

Deer and Wildlife Fence

Woven Deer and Wildlife Fence - Franklin Park Zoo

Woven from 12.5 gauge high tensile wire, this strong heavily galvanized fencing can be used with many different kinds of animals. All feature spacing between horizontal wires that graduate from small at the bottom to large at the top. Heights range from 4' through 10'. Horizontal and vertical wires are held together with fixed knot construction. Deer and wildlife fencing is available with a Class 3 galvanized finish. Some heights have a Class 3 black finish. The strength and height make this an ideal fence to use with a wide range of animals.
