Product Introduction
The railway fastener system is a cluster of core components that connect rails and sleepers in the track structure. It is mainly composed of spring bars, bolts, gauge baffles and elastic pads. According to the structural form, it can be divided into spring bar type, buckle plate type and spring plate type.
SKL series spring Clip fasteners use high-strength spring steel and provide stable buckling pressure through a unique arc design. They are widely used in high-speed railways and can withstand the high-frequency impact of trains at a speed of 350 kilometers per hour;
KPO buckle plate fastener system consists of carbon steel buckle plates and bolts. It has a simple structure and is easy to disassemble. It is suitable for daily railway maintenance and renovation projects;
Nabla spring plate rail fasteners achieve low-noise installation with thin springs, and perform well in space-constrained areas such as urban subway tunnels;
These systems mostly use alloy steel, engineering plastics and other materials, with both high strength and corrosion resistance, which can significantly enhance the integrity of the track structure, reduce the wear of the track by train operation, reduce maintenance costs, and extend the service life of the track.

Product Application
SKL rail fastener system
Generally used in track laying of concrete sleepers. The rails are fixed to the sleepers through the elastic force of the spring bar, which can provide a certain buckling pressure, keep the position of the rails stable, and adapt to different line conditions, such as straight and curved track sections.
KPO rail fastener system
The rails are fastened to the sleepers or track foundations through the cooperation of components such as buckle plates and bolts. This fastener system is used in some railway lines and can meet the rail fixing requirements under different track types and operating conditions. For example, it has better performance on heavy-load railways or lines with high requirements for rail fastening force.
Nabla rail fastener system
Nabla springs are usually made of materials such as 60Si2Mna and 60Si2Cra, with thicknesses of 4mm or 4.5mm, with certain elasticity and strength, and can provide reliable buckling pressure. The insulating blocks are made of reinforced nylon 66 (PA66) material and are used to achieve electrical insulation between rails and sleepers to prevent short circuits in track circuits.
Product Packaging & Delivery
When packaging and shipping fasteners, modular magnetic splicing boxes are used. Each splicing box has a strong magnetic sheet at the bottom and card slots and blocks on the side. The fasteners are classified and placed on the soft velvet padding in the box. Multiple splicing boxes can be freely combined into different shapes. The combined whole is placed in a hard plastic outer box, and the gaps in the box are filled with inflatable cushioning bags. After the box cover is closed, it is locked with a password lock, which is convenient for flexible combination and safe transportation.
