Concertina Wire

☼ Concertina Wire Description

Concertina wire is a type of razor wire that is one of the most widely used. It is used as a security measure to prevent unauthorised entry or intrusion. It consists of coils of wire with sharp edges which are interwoven and designed to form an impenetrable barrier.

Concertina wire is usually used in high security areas such as military and prisons, airports and government buildings, as well as in border fences to prevent illegal immigration and smuggling, and to protect homes, factories etc. It is very effective in deterring intruders.

☼ Concertina Wire Features

• • The raw materials are made of hot-dip galvanised steel sheets and hot-dip galvanised wire, or stainless steel sheets and stainless steel wire, which are very resistant to corrosion and can be used for more than ten years without rusting.

• • High strength steel, high tensile strength, high hardness, good elasticity.

• • Can be used independently or installed on top of the parapet or wall, easy to install, easy to transport.

• • Unique shape, will not be easily destroyed, intruders difficult to cross.

☼ Concertina Wire Details and Types

Concertina wire is the most widely used type of razor wire and can be divided into two categories depending on its construction: single coil concertina wire and crossed type concertina wire.

• • The single coil concertina wire is made up of several consecutive single spirals, usually with the CBT60 or CBT65 blade type. This type of Concertina wire is simpler, less costly, lighter and easier to install and is suitable for simple security applications such as residential protection, factory security etc.

• • The crossed type concertina wire, which uses clips to connect two adjacent spirals to form a tighter structure, provides a significant increase in security compared to single coil concertina wire. This makes intrusion more difficult and is suitable for applications with higher security requirements, such as battlefields, military bases, prisons, airports, etc.
  

☼ Other Types of Razor Wire

Razor Wire includes concertina wire, straight razor wire, flat razor wire and Razor Wire Fence etc. Hua Guang Fence Company is a razor barbed wire manufacturer, can produce them all. Please feel free to contact us if you require.

☼ Production of Concertina Wire

1. 1. the raw material is first stamped to form razor shaped sheets.

2. 2. The second step is to wrap the razor shaped sheets onto hot-dip galvanised steel wire or stainless steel wire, which then forms the semi-finished razor barbed wire, in which step the razor barbed wire is also coiled into a customised roll of diameter and number of turns.

3. 3. In the third step, if a crossed type concertina wire is required, the coiled razor wire is then clamped onto the clips.
   
   

☼ Package of Concertina Wire

1. The concertina wire is be packed in woven bags, waterproof paper or plastic bags.

2. The concertina wire is be packed in cardboard boxes.

3. The concertina wire is be any other packaging can be customised.

☼ Applicaion of Concertina Wire

The concertina wire is easy to transport and install and is used in a wide range of applications such as prisons, airports, borders, military bases, trenches, as well as residential and home fences, etc. It can be installed on top of fences or walls or can be installed independently to form razor wire fences.
