* Barbed Wire Fencing
Barbed wire fence is a free-form fence style. It utilizes vertical posts but the horizontal part of the fence is made of stretched sheets of barbed wire. You can hang as much wire between posts as you think is required. Barbed wire is available in sizes from 15.5 gauge to 12.5 gauge with a choice of two or four barbs and comes in 440-foot-long coils.
* Welded Wire Mesh Fence
Welded wire mesh is used to fence in smaller stock such as goats and sheep. It has 2" x 4" squares in 48-inch-tall 100-foot rolls. This wire may be attached to wood posts with fencing staples or on metal T-posts with wire clips. This type of fencing will hold animals that don't rub on fences much or cause them too much wear and tear.
* Field Fence
This type of wire mesh fence is sold in 330-foot-long rolls and is ideal for the farmer with a lot of acreage. It may be attached to metal T-posts or wooden posts and is available in several types. The 48-inch-tall field fence is used with goats and sheep and may be tried with horses and cattle and other livestock that don't tend to push against the fence while eating over the top. The 50-inch-tall variety makes that more difficult for the same types of animals or you can purchase and hang a 58-inch-tall version that is called horse-safe fencing. It prevents horses from leaning over the fence and weakening it, eventually leading to breakage. There is also a no-climb horse fence fashioned with two-inch squares that prevent animals from catching their feet in it.
