GFN Liner

GFN Liners are polymer-based railway fastening components used in compatible rail-seat assemblies. They are fitted between designated components to provide the required interface within the fastening system. Depending on the specified design, they can contribute to electrical insulation, wear management, and protection of mating surfaces. Their material composition and dimensions must match the intended rail fastening arrangement. We manufacture and supply GFN liners according to applicable railway specifications.
