Wire for ropes

GOST 7372-79
Rope wire is manufactured
  • by type of surface: uncoated, galvanized
  • depending on the surface density of zinc groups: C, W
  • by mechanical properties: grades – B and I
  • by temporary tear resistance, N/mm2 (kgf/mm2): marking groups – 1370 (140) - 2160 (220)

Purpose

The wire is intended for the manufacture of steel ropes, as well as for armoring geophysical and fiber-optic cables.
