Wire Fence

On the model form of woven-wire fence, the tensile strain figures to a very small degree. What the manufacturer aims to accomplish is to produce a hard wire without having this of spring-steel grade, so that it will stand more or less abuse and still not be so hard but that it can be spliced. Some types of fence are of rather weak construction, and for top and bottom wire high carbon steel is used to hold up the fabric.

Gauges, sizes, and weights of plain wire

Barb-wire.

In barb-wire fencing, it is reasonably safe to estimate that four-point cattle barb-wire (which means barbs approximately five inches apart) weighs about one pound to the rod ; and that four-point hog barb-wire (barbs about three inches apart), measures about thirteen feet to the pound.

Galvanized coiled spring-steel wire.

Coiled or wavy wire is employed in making fences in various forms, although it is not used to any great extent. It is so coiled that it will retain its springiness against all expansion and contraction due to weather conditions.
