High tensile (H-T or HT) fencing is a special hard, springy steel wire [6] that was introduced in the 1970s and has slowly gained acceptance. The wire may be a single strand plain or barbed wire, or woven mesh, and is capable of much higher tension than mild steel .
Barbed wire fence in line brace. The most important and most time-consuming part of a barbed wire fence is constructing the corner post and the bracing assembly. A barbed wire fence is under tremendous tension, often up to half a ton, and so the corner post's sole function is to resist the tension of the fence spans connected to it. The bracing ...
Smooth steel wire is the material most often used for electric fences, ranging from a fine thin wire used as a single line to thicker, high-tensile (HT) wire. Less often, woven wire or barbed wire fences can be electrified, though such practices create a more hazardous fence, particularly if an animal becomes caught by the fencing material ...
Typical chain link perimeter fence with barbed wire on top. The following types of areas or facilities often are required by law to be fenced in, for safety and security reasons: Facilities with open high-voltage equipment (transformer stations, mast radiators). Transformer stations are usually surrounded with barbed-wire fences.
Barbed tape on a fence. Razor wire has a central strand of high tensile strength wire, and a steel tape punched into a shape with barbs. The steel tape is then cold-crimped tightly to the wire everywhere except for the barbs. Flat barbed tape is very similar, but has no central reinforcement wire.
From the early 1960s, high-tensile 12½ gauge (2.5 mm) steel wire has largely replaced number 8 wire for New Zealand fencing, as it is lighter and cheaper, though also more difficult to work. [4] Since 1976, when New Zealand adopted the metric system , number 8 wire is officially referred to as 4.0 mm gauge wire, although the older term "Number ...
