Border line with razor barbed wire fence generally uses large diameter knife circle of double spiral razor barbed wire, such as 700mm-980mm circle warp. Can be multi-circle stacking arrangement, or small and large circle double circle stacking, in order to improve the ability to prevent overturning. Knife barbed model selection principles are high hardness, knife sharp, knife spacing should be densely arranged, anti-corrosion treatment process should be able to adapt to the local geographical environment and meet the expected service life requirements. Double spiral razor barbed wire fence, through the appropriate number of snaps will be adjacent to the knife circle in the circumferential length of the direction of equal intervals fixed, the material arrives at the construction site in accordance with the design of the installation spacing stretch to form an accordion-type spiral cross mesh cage shape. The larger the circle is designed, the more snaps should be appropriate to increase the number of snaps.
Razor barbed wire standard knife barbed models are listed below, the design is to give preference to standard models.
