We offer to use the order delivery service, because. rails are quite specific cargo that requires special delivery conditions, and we can provide them. Our company has various types of special equipment, with the help of which the order can be delivered under any weather conditions directly to the construction site.
Application of R-24 rail
The scope of R-24 rails is the construction of narrow gauge railways. Such paths are laid, for example, in mines. Reliability and strength are guaranteed by the quality of the steel, so rails of this type can be safely used when laying freight roads underground or in the manufacture of tracks for the movement of cranes, for trolleys and even for the construction of technological lines. Distinctive characteristics: increased wear resistance, ability to withstand loads with significant dimensions. Depending on the application, there are two types of these metal products: external and internal. External ones are great for connecting enterprises, factories, various industrial facilities and railway junctions. Internal serve as a link between workshops, warehouses, all kinds of strategic premises of one enterprise. Our company is engaged in the sale of rolled metal products at competitive prices with short delivery times throughout Russia.
Production of R-24 rails
The main component in the manufacture of R24 narrow-gauge rails according to GOST 6368-82 is high-quality steel grades H50, PT70 and T60. The places of curvature on a straight rail cannot be more than 3 mm per meter, and at the ends - 2 mm. During production, both ends are cut at an angle of 90 degrees without chipping. How much do rails cost? You will receive the answer to this question using an online calculation or a telephone consultation with our specialist.
Specifications
The list of technical characteristics of the R24 rail is clearly spelled out in the GOST standards:
- Height - 10.8 cm.
- Sole width - 9.2 cm.
- Head width - 5.1 cm.
- Neck thickness - 1.05 cm.
- The mass of a meter element is 24.9 kg.
- The cross-sectional area is 31.79 cm².
- The resistance of the upper head is 91.02 cm³.
For connection, it is advised to use traveling bolts of size m18x88, overlays P24. For a more convenient installation of the element, a special-purpose lining P24 is used, it is supported by a crutch 14x14 in size. The main application of R24 rails occurs in the creation of railway communication facilities. We are engaged in the implementation of various types of rails of three types: new, used and reserve.
Design features of R-24 rails
The shape of the narrow-gauge rails P24 differs from the rails of a wider gauge: the side faces of the head are in a vertical position, and the neck has a straight outline.
P24 rails are considered to be the ideal option for the formation of internal tracks in enterprises and factories, since there is no need to use long rails. R-24 rails are distinguished by type of length:
- from 3 m to 12 m - random length
- 8 m - measured length
- 7.87 m - a shortened version of the measured length for the construction of curved track sections
It is possible to buy rails at a price per ton. If you have chosen this particular method of evaluating this product, then you should contact our managers to make an individual calculation for the order or use the calculator on the website for recalculation yourself.
Important information about transport and storage
Placement in an open area allows for safe storage of rails. The main task of the platform is to be convenient for loading and sending transport in the future. Consider the rules below to correctly prepare the storage location:
- It is necessary that the site is located at a low height in relation to the surrounding objects.
- The design of the territory for storage takes place taking into account the flow of water.
- The site must be covered with sand and gravel, then rammed.

Technical characteristics of rail R 24 and R 18
Rails p24 and p18 are used for laying and repairing narrow gauge railways. But the main area of application is underground mine tracks, trolley tracks, technological production lines, overhead crane tracks and supporting crane beams. Also, the type of rail R24 can serve to replace worn-out crane rails KR-50 and full-bodied squares 50x50 st3 SP, which are no longer produced. According to the field of application, rails R 18 and R 24 are divided into external ones, which connect the raw material bases of various industrial enterprises, warehouses and wharfs , railway junctions, etc., and on internal ones, which are laid on the premises of an enterprise, factory, industrial warehouses.
The dimensions and technical parameters of the rail r-18 and r-24 must correspond to the calculated values presented in table 1.
Table 1 - Calculated values of rail dimensions R-24 and R-18
The value of the mass depends on the density of the steel. The table shows the calculation for ρ=7830 kg/cm³.
Figure 1. - Cross-section and dimensions of the rail p 18
Figure 2. - Cross-section and dimensions of the rail p 24
During the production of rails, deviations from dimensions are allowed, which are regulated by GOST 5876-82 and are given in table 2.
Our company unites more than 10 enterprises in Russia manufacturing materials for the upper track of railways. We ourselves produce, store, transport and sell everything that is needed for the construction and repair of railways, both highways and secondary ones. In this regard, our prices are by far the most competitive and attractive to our competitors. Delivery of our goods is carried out anywhere in Russia, while transportation costs for our customers will be minimal because in every region of Russia there are warehouses with our goods. The delivery time of the goods is from 2 to 10 working days.
Welcome to our company website. You can buy rails from us at competitive prices using the convenient management interface of our online resource. Favorable prices, competent specialists, the opportunity to come and see everything for yourself - these are the criteria for cooperation that you will receive today.
Actually, the rails are steel beams that are used for the construction of roads, through which special-purpose vehicles and equipment will move. Thanks to our rails, you can build tracks in production halls and hangars, factories and warehouses. This will allow to establish conveyor production, to implement the delivery of goods and raw materials, to organize the arrangement of workplaces inside the premises.
The rolling stock, which will move along a two-line track, consisting of rails, will be a good money saver. This is due to the fact that electric locomotives of railway trains are powered by electric energy, which makes the process economical and gives the equipment a large traction force. The latter circumstance makes it possible to build entire tracks between production sites and state railway tracks, which makes it possible for freight trains to come here for loading. By the way, instead of production workshops, there may be a sawmill and a place for storing bulk materials, since, for example, crushed granite is delivered in this way.
The sale of rails from our company is made openly and with a guarantee of quality for our own products. This is due to extensive experience and the choice of high-quality raw materials. We guarantee that we will provide our products with straightness in horizontal and vertical planes, calculate the exact chemical and raw material composition of the metal, and, if necessary, produce rails according to your technical specifications.
We manufacture various types of rails, among which we should highlight heat-strengthened rails, which makes it possible to use these products both in severe frosts and in cases of high overheating due to excessive friction during frequent use. Quality control of rail production allows us to exclude defects, carry out flaw detection, and organize stamping of metal surfaces. All this gives you the opportunity to get rails in stock or on order, completely ready for use.
