The E-clip rail fastening system is a widely adopted solution for securing railway tracks, featuring E-clip fasteners along with iron pads or embedded fittings that connect the rails to the sleepers.
The Nabla clip rail fastening system is a commonly used solution for securing railway tracks, consisting of Nabla elastic clips and connecting plates that join the rails to the sleepers.
The SKL clip rail fastening system is widely used for both ballasted tracks and concrete sleepers.
The KPO clamp rail fastening system is a commonly used solution for securing railway tracks. It consists of KPO clamps, iron pads, and bolts that connect the rails to the sleepers.
The fist rail fastening system is firstly developed in Sweden. This rail fastening system is widely used in the railroad in South Africa, Zimbabwe, Botswana, Swaziland and Namibia. In addition, the railroad fastener is extensively employed in South America and Australia.
Both the clips and the toe insulators are installed at the parked position, where the side post insulators and pads are mechanically held in place.
Rail sleeper screw spikes are used to fasten sole plates and ribbed base plates to wooden sleepers. In rail construction with the concrete sleepers, the rail sleeper screw is used in combination with a plastic dowel pressed in the concrete sleeper, indirect or direct fastenings of rails on concrete and wooden sleepers.
A rail spike is a large nail with an offset head that is used to secure rails and base plates to the sleepers in track. The rail spikes are roughly chisel-shaped with a flat-edged point.
Sticking to our quality first policy, SUYU pays great attention to quality control management. We have been granted ISO9001-2008 certificates and have received the production license of China's Railway Ministry on railway products. We have a full set of inspection instruments to ensure all our railway bolt products are of high quality and up to customers' requirements.
We are extremely capable of producing elastic rail clip for any type of toe load and axle load requirements to fix the rails on wooden, steel or concrete sleepers. We offer various elastic rail clip with size steel bar diameter from 12mm to 20mm.
Our rail cast iron shoulders include M.C.I. shoulder manufactured from pearlitic malleable iron and S.G.C.I. shoulder manufactured from spheroid graphite iron.
Rail anchor is manufactured in one-piece construction for spring steel or equal, heat-treated and designed to eliminate creepage of track. The rail anchors provide a large bearing surface against both rail base and tie, avoiding undo cutting and wear, thus prolonging the life of wooden ties.
Tie plates are generally used to take the load of rail and distribute the load to the sleepers offering proven economies. We manufacture all types of base plates suitable for various rail sections, for use on wooden, steel or concrete sleepers and ballast-less tracks used with elastic fastenings on wooden sleepers and 'K' type fastening system.
Adhering to our quality first policy, SUYU pays great attention to quality control management. We have been granted ISO9001-2008 certificates and have received the production license of China's Railway Ministry on railway products.
We produce E type rail insulator and guide plate for SKL rail fastening and Nabla fastening system. The material we use for rail insulator is PA66, with the color white, dark brown and black.
Rail plastic sleeve is pressed in concrete sleeper and assembled with sleeper screws, guide plates and rail clip to fix the rail. Our rail plastic sleeve is made using either HDPE or PA66 and the product color is available in white, black and dark brown.
We deal in all types of fish plate, also known as joint bar, splice bar and angle bar. We have in-house rolling, forging, machining, and drilling and punching facilities to ensure accurate rail fish plate size.
SUYU can offer diversified train wheels like the casting wheel and forging wheel. After a series of productive progresses, such as vacuum refining for raw material, continuous casting process, heat treatment controlled by computer, tests by advanced inspection equipment, and CNC profiling, we can offer the product with the diameter ranging from 360mm to 1250mm.
The brake disc can be made of grey casting iron, forging steel or alloy steel. The product falls into categories of the wheel brake disc and the shaft brake disc and has applications on locomotive and coach.
SUYU provides railway coupling system and parts by the standards of YB, AAR, and UIC. The customized coupling system solution is also available.
The axle supports adopting many kinds of steel as raw material, such as, LZ50, JZ45, AAR Grade F, EA1N, EA1T, EA4T, IRS 16/95, and SFA60A. We accept axle orders of small quantity or of demanding complex designs on customized requirements.
The yield strength and fatigue limit of the material interact with each other. Generally speaking, higher yield strength comes with higher fatigue strength.
With the effort of 50 technicians, SUYU develops diversified axles with different sizes and types that have various applications. Meanwhile, owing to our strict quality control system, the product enjoys high quality and a good reputation all over the world.
Our cast iron brake block enjoys many advantages including hardness, impact strength and so on. It consists of two parts, the cast iron and the steel support.
The large thread design on the socket allows the tunnel bolt to be inserted 4 to 5 times faster than traditional metric thread. The design of the threads utilizes the strength of the concrete (as the load is transmitted through the concrete) therefore not relying on the strength of the plastic. This tunnel bolt is available in any length, grade, and finish to suit customer requirements.
