Diagram:

Construction:
Barbed wire consists of wire enclosed with metal band – blades and tied with staples;
 The barbed wire is wrapped in rolls and is expandable from them.

Minimum elasticity of metal wire according to1400 MPA.

Blades:
Thickness 0,5 mm (±0,2 mm);
Blade type BTO22;
Zinc coating according to ISO 550 standard, minimum galvanizing 200 gr / m2;
Cutting (tear off) force of blades from wire — not less than 450 N;
Symmetrical blades on both sides, with a total width 15 mm (±2 mm);
Blade length – 22 mm (±2 mm);
Distance between blade centers35 mm (±2 mm).

Staple:
Number of staples – 3 (for the diameter of the outer roll 400-600 mm);
Number of staples – 4 (for the diameter of the outer roll 700-800 mm);
