Security fencing ensures that whatever is enclosed within it is safe from intruders and it also keeps the public safe from wandering into a place that may not be safe for them. It can surround residential property, commercial establishments and even industrial sites that are many hectares in size. There are several different types of fencing and what you need will the dictated by the kind of establishment you want to surround, where it is, the length the fence needs to be and your budget. Here are some different kinds of security fencing.
- Chain link fencing. This kind of fence has a diamond mesh body with two diameters; 2.50mm or 3.15mm. The mesh is galvanised or PVC coated. The top of the fence can be two or three strands of barbed – razor – wire, which can also be Y-shaped or double Y-shaped so that it extends over the verticals on each side. It is highly effective and is used for mine sites, construction sites, sporting fields and anywhere that high security is essential.
- Welded mesh fencing has smaller mesh that cannot provide a toehold. Finishes and tops are similar to above, or can be electrified.
- Garrison fencing. This is made from heavy tubular steel that is either powder-coated or hot galvanise dipped and offers even more protection than chain link. It can be from 1800mm to 3000mm high. While it is more expensive than mesh, it offers aesthetics as well as more security. It is commonly used for government property, schools, sporting facilities and commercial infrastructure.
- Palisade fencing. Palings that are hot dipped galvanised with the option of powder coating are fixed to horizontal rails in a way that is secure and cannot be tampered with. The top can be curved razor taped, or have an electrical extension. Concrete plinths ensure a no-dig finish. This is one of the most secure fencing options of all and is suited to anywhere high security is required.
Not all fencing is erected to keep people in or out; stock fencing is also a security fencing option to keep cattle, sheep, horses and other animals within a paddock or enclosure so they don’t wander onto roads. Each animal species requires a different type of fencing.
- Cattle have tough hides and a low flight or fight reaction so can be held with barbed or plain wire strands or electric fencing.
- Horses have a high flight or fight reaction and thinner skin, so post and rails or mesh are more suitable. If barbed wire is used it should be capped with a rail to prevent injury.
- Sheep have thick wool that allows them to push through barbed wire without injury so they need mesh fencing of some kind need mesh or interlocking wires to keep them safe.
