Roll Type Barbed Razor Wire Fence fixed with clips single or cross coil
Barbed razor wire about
Razor wire has a central strand of high tensile strength wire, and a steel tape punched into a shape with barbs. The steel tape is then cold-crimped tightly to the wire everywhere except for the barbs. Flat barbed tape is very similar, but has no central reinforcement wire. The process of combining the two is called roll forming.
Types
Like barbed wire, razor wire is available as either straight wire, spiral (helical) coils , concertina (clipped) coils, flat wrapped panels or welded mesh panels. Unlike barbed wire, which usually is available only as plain steel or galvanized, barbed tape razor wire is also manufactured in stainless steel to reduce corrosion from rusting. The core wire can be galvanized and the tape stainless, although fully stainless barbed tape is used for permanent installations in harsh climatic environments or under water.
Barbed tape is also characterized by the shape of the barbs. Although there are no formal definitions, typically short barb barbed tape has barbs from 10-mm to 12-mm long, medium barb tape has barbs 20-mm to 22-mm long, and long barb tape has barbs from 60 to 66-mm long.

According to the barbed razor wire structure
Helical type: Helical type razor wire is the most simple pattern. There are no concertina attachments and each spiral loop is left. It shows a natural spiral freely.
Concertina type: It is the most widely used type in the security defense applications. The adjacent loops of helical coils are attached by clips at specified points on the circumference. It shows an accordion-like configuration condition.
Blade type: The razor wire are produced in straight lines and cut into a certain length to be welded onto the galvanized or powder coated frame. It can be used individually as a security barrier.
Single coil: Commonly seen and widely used type, which is available in both helical and concertina types.
Cross coil: A complex razor wire type to supply higher security grade. A smaller diameter coil is placed inside of the larger diameter coil. It is also available in both helical and concertina types.
