railway rubber pad manufacturers - GNEE RAIL
Railway rubber pad is an important part in rail structure, which is the connex of rails and concrete structure parts in order to protect from vibrating and impacting.
GNEE RAIL is equipped with rail pad production lines for 130sets of machines, for the whole process of injection, refining rubber, sulfuration, moulding and inspection, etc. We own the most engineers for rail pad development, design, production and inspection, with annual production capacity reaching up to 2000, 000 pieces. What's more, rail pads for high speed rail lines are our featured products, including both the elastic rubber plates and height adjustment pads.
Our EVA/HDPE/rubber rail pads are with high elasticity, applying to types for rails such as rail UIC54, UIC60, BS80lbs,BS100lbs, and sizes as ordered. The pads can be customized with or without grooves, in various possible designs, depending on customers' requirements.

Features of Rubber Rail Pad from GNEE RAIL
Shock absorption, ageing resistance, abrasion resistance, stability, thermal stress resistibility. Rubber rail pads are made of natural rubber, butadiene-styrene rubber, chloroprene rubber adhesive, HDPE and EVA. The rubber rail pads made by GNEE RAIL has many features like high elasticity, non-deformation and non-breaking in a large range of temperatures.
Long service life, low maintenance and replacement costs.
We can produce various standards of rubber rail pads with different materials, the rubber rail pads are suitable for wooden railway sleepers, concrete railway sleepers and steel railway sleepers.
