3. Wire is manufactured in bundles. A bundle comprises one section wire. Each bundle is fastened by soft wire in three points along the bundle circumference. Weight of wire bundle is:
  • Ø0,8-1,6 mm – 80 – 100 kg
  • Ø2,0-3,0 mm – 180 – 200 kg
  • Ø2,0-6,0 mm –1000 - 1200 kg

Wire can be transported by any carriers, in the covered cars securing protection from mechanical damage and ingress of moisture, and subject to due observance of freight regulations valid for the relevant transport facilities.
