No. of spirals per coil: 68
Diameter of coil: 1 Meter
Distance b/w barbs : 60 mm
Length of barbs: 15.81mm
Weight= 25 Kg Approx
Surface: Electro Galvanizing + Bitumen Paint (Both)
Packing: Each bundle to be packed in Hessian Cloth

Processing: The line wire shall be fitted with four point barbs of mild steel wire at distance between Centres of 60 ± 15mm. Barb wire is to be twisted tightly round the line wire with approximately 4 turns then sharp pointed in the form of a bevel at right angles to one another with a projection of 15-20 mm from the Centre line of wire.

The barbs should be set obliquely to the line wire, but must not be less than 45 angle. The barbs need be fixed in such a manner that under normal conditions they will not slide along the line wire when subjected to an axial force of 50 Newton. The barbs should not rotate when subjected to torque of 0.1 Newton meters.

After barbing, the line wire shall be formed into coils of 68 ± 1 turns each being approximately 1 meter in diameter. The adjacent coil shall then be clipped with mild steel clips at intervals of approximately 72 degree. Each turn being clipped to the preceding turn by alternate clips and to the succeeding turn by the remaining clips. This should result in the clips being spaced around the coils in 5 tows so that a diamond pattern is produced when extending the coil into a cylinder 15 meters long ± 1/2 meter, and when closed into a coil without distortion.
please note that this is High tensile Wire, not the regular barbed wire.

Barbs Spacing 1.96"--5.90"
Wire Gauge： 12 gauge to 15 guage.

Single Twisted Barb Wire or Double Strand:

The choice between single barbed wire and double strand barbed wire largely depends on the specific security needs, budget, and installation considerations of a project.
Single strand barbed wire is mainly used for less demanding fencing situations, offering ease of installation and cost-effectiveness, while Double strand barbed wire offers higher security and strength, suitable for more critical applications.
