SKL 12 rail Concrete Sleeper Elastic Rail Clips With color painting
We are engaged in manufacturing and supplying elastic rail clip products which are exclusively used in railways. Fabricated with optimum quality raw materials, these elastic rail clips are designed with high precision which impart high tensile strength and corrosion resistance. Our products can also be customized according to clients' requirement at a client desired price.
The rail elastic clips are used with concrete sleeper to fasten rails on both sides. The rail clips are usually made of forged spring steel, which are manufactured by hot forging process. The forged rail clips are considered to be better than other metal forming process due to most uniform microstructure.
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.
