The GRANUFLEX-RAIL® product range is a result of decades’ worth of manufacturing experience and years of research and development. The development of every single product type and the testing of experimental products were carried out with the involvement of the faculties and laboratories of the Budapest University of Technology and Economics and the Széchenyi István University in Győr.

The GRANUFLEX-RAIL® noise and shock absorbing products have been installed throughout Europe and in other parts of the world.
