Concertina wire is by far one of the most perfect physical obstacles. Security barrier made of galvanized steel strip thickness of 0.55 mm - 1.5 mm, having a double-edged, symmetrically spaced, directed spines, and reinforced with high carbon galvanized wire diameter of 2.65mm, 2.8mm, 3.0mm. Nominal diameter of the razor concertina is 450 mm, 500mm, 600mm, 730 mm, 900mm, 980 mm (after stretching, the diameter is reduced by 5-10%).
Single Coil Razor Wire Forms: straight ribbons or single coil concertina.
Characteristics: Single coil barbed type wire is installed without clips. It runs in natural loops on walls. Costless and can be easily installed.
Cross concertina wire coil is two pieces of stainless steel razor wire or zinc-coated wire bound together by clips to make it stronger. This galvanized wire tape compresses the core, and adjacent turns of the cramp in five equidistant points on a circle. Total installed 3 or 5 rows of staples, so that it becomes formidable concertina, springy, spatial design. The spiral intersecting barbed wire presents an intersecting shape after opening. After stretch and installation, concertina creates a fixed and strong spatial structure. In order to overcome this type concertina wire, it must be cut at least three points.
Double Concertina Razor Coil includes two razor concertina coils with different diameters, and small diameter concertina is included in the large diameter concertina. Three nodes connect the two concertina razor. Double concertina razor wire has more beautiful appearance and better protection than other razor mesh.
