Fatigue property is no less than 5 million times .

Loading property : under pressure 8-12KN , the displacement is between 9-12mm .

?

We? produce PR series Elastic clip , such as PR309.PR401.PR601

?

The Nabla clips are also within our range ,the hardness is HRC51-55 and they have excellent elastic property ,with load 2500DaN , after the first two tests , variation of the height after releasing is only 0.45mm and after the three more tests , there is only 0.1mm variation of height , the finished Nabla clip can be painted red or other colors according to the requirement of our client .

?

We also produce the special rail clip according to our customers& acute; requirement .

?

As a leading manufacturer of rail fastening in China , SUYU also can produce many other railway fasteners , such as track bolt . Sleeper screw . rail anchor .rail joint bar . tie plate .rail clips ,.rail shoulder and so on .
