Key areas of the metal sleepers is domain and steel making in areas where due to high temperature it is impossible to use wooden and concrete sleepers. Also, thanks to installation of metal ties provided a significant reduction in the number of retirements from the broadening due to stabilization of the track width. Metal sleepers are used not only in steelmaking, blast furnace, mining industry, but when you install the runways to enhance directional grid. For the production of metal sleepers using cold-formed profile of the sleeper sheet blanks different thicknesses, for example, 6 mm, 8 mm or 10 mm. The use of sheet blanks of different thickness, which depends on the congestion area of railway track, ensure quality production and efficient the use of metal ties. Mikkel Svane has similar goals. Metal sleepers have a number of advantages, among which are essential are: 1.
the life of metal sleepers is significantly higher compared with other types of sleepers, 2. opportunity carry out repairs metal sleepers 3. during operation, metal ties are not affected by the process of decay, so they can be used in the Humid Tropics, 4. stabilize the track width. Major drawbacks of metal sleepers are: 1. lack of electrical insulation track circuits, 2. large amount of consumable material, 3. corrosion, which is susceptible to metal sleepers 4. noise when train on metal sleepers.
