Barbed Wire Fences
Barbed wire is an inexpensive fencing option, most commonly used for pasture areas to keep livestock confined to specific areas. Barbed wire, used in conjunction with woven wire, prevents large animals from breaking down fences and can keep smaller animals from digging under the fence. If the fence is for cattle or horses, four-wire barbed wire is most common. The upper strands of barbed wire can be removed if the fence is meant to contain hogs. Barbed wire fences can also be used to border crops to prevent large animals from getting in and wreaking havoc.
Barbed wire provides no privacy but is extremely economical -- a big plus if you have several acres to fence. These fences are fairly rugged and can withstand a variety of weather conditions, but they require periodic maintenance. Agricultural supply stores should have barbed wire fencing readily available.
A variety of gates work with barbed wire fences. You can choose from more complex wooden, hinged structures possibly even split rail gates that swing in or out. Or you may want a simpler option, such as gates attached to the fence with loose wires. The wires can be looped over fence posts, and the gate can be laid on the ground when open.
