Railway Clip and Clamps - High Strength Rail Clip and Rail Clamps with E Shape 60Si2MnA
Rail elastic clip is used to fasten the rails to the underlying base plate together with the concrete sleeper. Usually rail clips are made of forged spring steel which is produced by hot forging process. Because of the uniform microstructure of forged clips, it is considered to be better than other metal forming process.
Our customers widely seek this product in the market attracted by the various salient features that are as follows:
For all types of elastic rail clips:
Rail clips processing procedures are as follow: Shearing-- Heating to forging temperature -- Forming-- Hardening—Tempering — Inspection — Packing.
Enriched with rich railway industrial experience, ZhongYue can offer its clients an extensive range of heavy duty rail fastening clips, made up of premium quality and seamless performance, to be used to fasten rails to underlying tie plates. The rail clips produced by ZhongYue are made up of premium grade spring steel sourced from a reliable and certified long term producer.
After over 10 years’ experience on producing rail elastic clips, ZhongYue has become the largest and most competitive production base of rail clips in China, qualified to tender nationally large and medium scaled rail projects under the China Ministry of Railways, both at home and abroad.
At each single step of manufacturing the clips are stringently tested and completely authenticated. To save time during installation in track, we can provide a special service by pre assembling a SKL clip with a T-bolt and a washer for the customer at our production base before delivery. Besides, corrosion protection layer of the clip surface can be applied.
