Customized Black Or Red Rubber Rail Support Pad / HDPE Pad Below Rails
Rail and Support Pads
Zhongyue have been supplying track support products to the rail industry for many years.Manufactured in a
variety of natural and synthetic elastomers, SUYU railpads are designed to withstand the most demanding
operating environments.
Zhongyue railpads offer the following benefits:
1. Dramatically Improved Impact
2. Attenuation Noise Suppression
3. Improved Passenger Comfort
4. Extended Track Life
5. Extended Ballast Life
Zhongyue in a joint initiative with a major world producer of rail track fastening systems analysed and
developed a resilient pad concept to protect concrete rail sleepers from damage caused by the dynamic
forces of passing trains. The result was the Patented Studded railpad.
Over 45 Million of these rail pads are now used successfully Worldwide, including the USA, Canada,
Australia, Norway, Sweden, Denmark, Belgium, France, Georgia, Lithuania, Hong Kong, Japan, Korea,
Czech Republic, Uzbekistan, Syria, Singapore, Sudan, Estonia, Finland and extensively within the UK.
The combination of studded design and specially formulated rubber compound, gives SUYU patented
rail pads a unique high resilience and abrasion resistance.
Their superiority to those manufactured from other materials has been proven by their ability to reduce
dynamic forces by up to 65%, which is a crucial consideration for railway systems worldwide as they adopt
higher speeds and greater axle loads.
