Fence

From Wikipedia, the free encyclopedia

This article is about the structure. For other meanings, see Fence (disambiguation).

Image:Westtown.jpg A fence is a freestanding structure designed to restrict or prevent movement across a boundary. It is generally distinguished from a wall by the lightness of its construction: a wall is usually restricted to such barriers made from solid brick or concrete, blocking vision as well as passage (though the definitions overlap somewhat).

Fences are constructed for several purposes, including:

Agricultural fencing, to keep livestock in or predators out
Privacy fencing, to provide privacy
Security fencing, to prevent trespassing or theft and/or to keep children and pets from wandering away
Decorative fencing, to enhance the appearance of a property, garden or other landscaping

[edit] Types of fences

Some of the technologies developed for fencing include:

Barbed wire fence
Cactus fence
Chain link fencing
Dry-stone wall or rock fence, often agricultural
Electric fence
Ha-ha (or sunken fence)
Hedgerows of intertwined, living shrubs (constructed by hedge laying)
Palisade
Pet fence Underground Fence for pet containment
Picket fences, generally a waist-high, painted, partially decorative fence
Post-and-rail fencing
Split-rail fences made of timber, often laid in a zig-zag pattern, particularly in newly-settled parts of the United States and Canada
Snow fence
Stake-and-wire fencing
Turf mounds in semiarid grasslands such as the western United States or Russian steppes
Wood-panel fencing

Alternatives to fencing are a hedge or a ditch (sometimes filled with water, forming a moat).

A balustrade or railing is a kind of fence to prevent people from falling over the edge, for example, on a balcony, stairway (see railing system), roof, bridge, or elsewhere near a body of water, places where people stand or walk and the terrain goes steeply down, and so on.

[edit] Requirement for fences

Image:DFRFence.jpg The following facility types have to be fenced in:

facilities with open high-voltage equipment (transformer stations, mast radiators). Transformer stations are usually surrounded with barbed-wire fences. Around mast radiators, wooden fences are used to avoid the problem of eddy currents.
railway lines (in the UK)
plants with dangerous mobile parts (for example at roundabouts on entertainment parks)
explosive factories and quarry stores
most industrial plants
airfields
military areas
prisons
zoos and wildlife parks
open-air areas that charge an entry fee
domestic swimming and spa pools (in New Zealand)

[edit] Legal issues of dividing fences

Fences can be the source of bitter arguments between neighbours, and there are often special laws to deal with these problems. Common disagreements include what kind of fence is required, what kind of repairs are needed, and how to share the costs.

In some legislatures the standard height of a fence is limited, and to exceed it a special permit is required.
