Welcome to Anping County Boli Hardware Wiremesh Products Factory – a professional manufacturer established in 1998, specializing in railway fastening components. Our Spring Rail Clip is engineered to deliver reliable performance under demanding conditions, backed by a 1-year warranty, a comprehensive Mill Test Report, and 100% QC inspection to ensure every piece meets your exact requirements. With over two decades of manufacturing experience, we take pride in offering high-quality products that keep railway systems safe and efficient.
Our spring rail clips are produced from premium carbon steel (such as 60Si2Mn and 55Si2Mn) and undergo strict heat treatment processes to achieve optimal hardness and elasticity. The clips are designed to provide consistent clamping force, effectively securing rails to sleepers while absorbing vibrations and impacts from passing trains. Whether you are upgrading existing rail lines or constructing new ones, our clips offer a cost-effective solution with long service life.
