RAILROAD RAILS

Railroad rails are steel beams, special sections, laid on sleepers or other supports for the formation of a two-line path that moves the rolling stock of rail transport, urban Railways, specialized staff in mines, quarries, crane equipment.

Rails for a railroad transportation are made of carbon steel. The most common in the CIS countries the following types of rails: R50, R65, R75.

Railroad rails are divided as follows:

by types:

  • R50;

  • R65;

  • R65K (for external threads curves plots the path);

  • R75;

by categories of quality:

  • V –  heat-strengthened rails of the highest quality;

  • T1, T2 –  heat-strengthened rails;

  • N – not heat-strengthened rails;

by the presence of bolt holes:

  • with holes on both ends;

  • without holes;

by the method of steelmaking:

  • M – from open-hearth steel;

  • K – from converter steel;

  • E – from electric steel;

by referring to the source of the blanks:

  • from ingots;        

  • from continuously cast billets

PILE

Pile is metal profile, which is a chute with rounded edges of the side walls (slots) or locks. Piles can be connected in section 2 or 3 of pile. The length of the piles can reach up to 34 meters. In addition to the trough-shaped profile, there is producing the Z-shaped one and flat pile with locks.

Among all the varieties of piles should be allocated pile with Larssen locks. Its advantages include corrosion resistance, convenience and ease of installation. Pile with Larssen locks is embedded in soil piling hammers or sank using the vibratory hammer. Each subsequent pile is plunged into the ground in a special groove on the previous and expanded on the first by 180 degrees. A continuous structure forms, which can be made in the form of a ring. Inside the construction water is pumped and conducted the necessary work. After completion of the work, the pile is removed and can be reused.

SHAFT STAND

The special interchangeable profiles for mine timbering are manufactured according to GOST 18662.

Length: 9 000-12 000 mm

Limit deviations in height: +1,0/-1,5 mm.

Twisting around the longitudinal axis is not allowed.

A wide range of structural shapes is always available in the warehouses of the Company.
