SKL elastic rail clips are widely used fastening components in modern railway track systems, primarily designed to secure rails to concrete sleepers or base plates while providing continuous and stable clamping force to prevent rail creep and gauge deviation. SKL elastic rail clips comply with international standards such as British BS970 and Chinese GB/T1222, and are applicable to high-speed rail, urban metro, heavy freight lines, and industrial railway tracks.
SKL clips manufactured by GNEE RAIL are made from high-performance spring steel materials, including 60Si2MnA, 60Si2CrA, and 55Si2Mn. These materials undergo precise heat treatment, offering high hardness, high fatigue strength, and excellent elasticity, allowing the clips to maintain stable clamping force and durability during long-term train operations. 60Si2MnA and 60Si2CrA are particularly suitable for heavy-duty and high-speed lines, while 55Si2Mn, with its good toughness and wear resistance, is ideal for general railway and industrial lines.
