Our certification
We have CRCC certification and ISO9001 quality management system certification.
High strength and high toughness: Premium materials, heat treatment, and spring bars can endure the tremendous pressure and impact force produced by train operation while also possessing a specific level of toughness that makes them difficult to break.
Good elastic performance: SKL clip can reduce wear between rails and sleepers, buffer track vibration and deformation when a train passes, prolong the track's and related components' service life, and give the train a stable operating environment because of their high elasticity.
Reasonable design: Reasonable design, stable and adequate buckle pressure, and the ability to firmly fix the rails in the designated position-even under long-term train loads-allow for the maintenance of the rails' correct position, prevent longitudinal and lateral displacement, and guarantee the track's geometric shape and position accuracy.
Excellent corrosion resistance: The product is long-lasting and appropriate for a range of hostile natural environments and climatic conditions. The surface is often subjected to a variety of treatment techniques to prevent rust and corrosion of steel.
Rapid installation: Rapid installation, replacement, and maintenance during railway construction and operation are made possible by the structure's relative simplicity, ease of installation and disassembly, high efficiency of railway track laying and maintenance, and reduction of labor intensity and construction costs.

Standard SKL clips: These are the regular clips made from cast steel. They are used in normal track sections where traffic is regular, and the track conditions are standard.
Heavy-duty SKL clips: These clips are made from high-strength steel. They are used in heavy-haul railway lines where very high axle loads are carried on the track.
Corrosion-resistant SKL clips: These SKL-3 railway clips are made using stainless steel or coated with corrosion-resistant materials such as zinc or epoxy. They are used in coastal or other environments where corrosion can quickly damage unprotected iron and steel components.
Vibration-damping SKL clips: These clips have features such as rubber insertions that help to reduce the transmission of vibrations and noise from the rolling stock to the track. They are used in high-speed railways or urban areas where vibrations and noise have to be minimized.
Adjustable SKL-3 railway clips: These clips can be adjusted to enable fine-tuning of track gauge and alignment. They are particularly useful in sections of the track that experience frequent changes in conditions or where precise geometry is critical.
Anti-loosening SKL-3 railway clips: These clips have designs or features that prevent the clips from becoming loose due to vibrations and dynamic loads. They might include locking mechanisms or use of more resilient materials.
Make sure the installation position of the SKL clip is accurate. The installation should be carried out in accordance with relevant standards and specifications to ensure that the SKL clip and the track are tightly combined and there must be no looseness or deviation.
Regularly check the status of the SKL clips. Since the SKL clips are exposed to the external environment for a long time, they may be affected by oxidation, wear, etc., so the status of the SKL clips needs to be checked regularly to ensure that they are working properly.
When using SKL clips, be careful to avoid overloading. The design load-bearing capacity of the SKL clip is limited. Overloading will cause the SKL clip to deform or be damaged, thereby affecting the safety of the track.
Process Quality Control of SKL Clip
Accurately design the mold to ensure that the product size is qualified. Strictly control the production temperature to ensure good temperature distribution. Regularly check the product size and surface quality.
