concertina coil wire

Barbed Wire is also named concertina razor wire, razor fencing wire, razor blade wire . Hot - dip galvanized steel sheet or stain-less steel sheet stamping out sharp knife shaped,stainless steel wire into a combination of wire block.It is a kind of modern security fencing materials with better protection and fencing strength made of hot-dipped galvanized steel sheets or stainless steel sheets. With sharp blades and strong core wire, razor wire has the features of secure fencing, easy installation, age resistance and other properties. Used in many high security applications, It is typically found in gardens, hospitals, industrial and mining enterprises, prisons, border posts, detention centers, Governments buildings or other security facilities. Also used for division of railways, highways, etc, as well as agricultural fence. Razor Barbed Type l Concertina single coil razor wire :The construction of single coil concertina razor barbed wire is based on strand of a single razor wire naturally running in loops without any clips or splices , where the diameter of loops is 30 ， 45 and 73cm .When stretched the concertina single coil razor wire forms a cylindrical obstacle structure , which is very hard to penetrate or cut through with hand tools .The diameter of coils when stretched may become smaller by around 5-10%. l Concertina cross razor wire :Concertina cross type razor blade wire is made of two pieces of ultra type razor wire bound together in a double spiral Razor wires are bound together by special steel clips ( between 3 and 9 clips for one coil depending on the width of the coil).The number of clips decides about the density of the coils ,and thus about the effectiveness of the obstacle . The more clips the harder the barbed wire is to penetrate. l Flat wrap razor wire :The construction of flat wrap galvanized razor barbed wire is made up of parallel placed overlapping loops with a diameter of 50, 70 or 90 cm made up of razor wire .The loops are connected with one another using special clips , which allows to attain a rigid obstacle border fencing which is very hard to penetrate.Razor wire flat fencing often functions as supplemental fencing together with traditional fencing ,which are much easier to penetrate like wire netting or panel fencing. In the construction of your project, according to the characteristics of your use environment, choose the appropriate type of razor barbed wire.
