Most of the fencing used in farms is made from metal because it is stronger than other materials. The strength and durability of the metal wire fencing used depend to some extent on the gauge of the metal wires which are used and how the wires are interconnected.
The American Wire Gauge (AWG) system is used for defining the size of the wires used in fencing. Unlike conventional numbering systems, a higher gauge number indicates a thinner wire, and the thickness of a wire of gauge ten will be more than a wire of gauge twelve. The different types of fencing are discussed below
However, for aesthetic reasons and practicality in open fields, wooden fencing is commonly used in the UK. Wooden agricultural fencing is a popular choice for many fans and country estates.
Most farmers use barbed wire since it is inexpensive, easy to use. It consists of two or three-wire strands, with pointed metal barbs connected at regular intervals. The barbed wire is connected to metal or wooden posts. This fencing is widely used to confine cattle
The Field fence is also a metal wire fence, however, the wire used is of a thicker gauge. The joints are crimped together so that they do not break easily.
The gauge of the wire used is usually twelve-gauge, however, the bottom layers and top layer may be made from thicker 10 gauge wire for greater durability. This fencing is used for pigs, cattle and other larger livestock.
Some of the variations of this fence are:
Woven field fence: The metal wires are woven to form a fence, and knotted periodically for greater strength. Some joints of the fence are crimped together to make the fence flexible so that it regains its original shape when a large animal will push it.
Some animals like goats, bulls and other cattle often ram into the fence, and this fence is suitable for these animals
Horse fence: It is made from wire, yet it is smooth on both sides, since horses or other animals may scratch their hides against the fence. To ensure that the hooves of the horses do not get entangled in the mesh, a V-mesh may be used.
Chicken wire is one of the most widely used fencing materials. The lightweight wire of 20 gauge is woven to form a grid with triangles of size one or two inches in size. This wire is sold in rolls whose width may vary from two to five feet.
In addition, to ensure that foxes, wolves, hawks, and other predators do not attack and eat the chicken and other poultry, the chicken wire can also be used for protecting gardens from pests.
This fencing is made with wooden posts, with two or three rails nailed to the post on each side. Since these posts require maintenance, they are mainly used for ornamental purposes.
One of the most effective ways to ensure that the animals do not escape is by giving them a mild electric shock, every time they brush against the fence wires. This fence has insulated wires, through which electric current will be passed, which are connected to insulated stakes.
Humans should be careful near this fencing since the electric shock is unpleasant. Special precautions should be taken by families with small children since it can cause them more harm.
Snow fences are used in the prairie region, with harsh winds, heavy snowfall, during winter, to prevent snow from blocking the driveway and roads. These fences are made by connecting wooden slats with suitable wires.
