STO 71915393-ТU 002-2015
To date, one of the most effective ways to reduce the severity of the consequences of an accident is the installation of dividing fences between oncoming traffic flows and retaining side fences on the roadsides.

In comparison with profile and concrete types of fences, cable fences have the following advantages:

  • increased safety for vehicles due to the high damping ability of ropes;
  • lower metal consumption;
  • lower cost of 1 km of fences;
  • ease and shorter installation time;
  • simplicity and shorter terms of replacement of elements and restoration of the structure in case of an accident;
  • increased service life;
  • lower operating costs.

Severstal-Metiz has developed three-strand ropes specially for cable fences of roads that meet all the necessary requirements of the Guidelines for the installation of cable road fences ODM 218.6.004-2011 (MADI).

Rope construction

In the production of ropes, the operation of pre-drawing is used, which provides the required elasticity to the product upon impact.

A thick zinc coating applied by hot-dip galvanizing prevents corrosion of the rope and significantly increases its service life.
