Railway fasteners are primarily categorized into rigid fasteners and elastic fasteners, which differ in structural characteristics, performance, and application scenarios.
Rigid fasteners represent traditional railway fastening devices, typically composed of fishplates, bolts/nuts, spikes, and rail pads. They secure rails to sleepers or track slabs through rigid connections, featuring simple structures and low manufacturing costs. Commonly used in low-speed railways, industrial/mining lines, and some aging tracks, rigid fasteners lack elastic buffering capacity. Under high-speed train operations or heavy-load impacts, they tend to cause accelerated wear between rails/sleepers and fatigue damage to track structures, leading to their gradual replacement by elastic fasteners in modern railways.
Elastic fasteners utilize elastic components (such as SKL clips, KPO clips, Nabla fasteners, Fast Clip, and E Clip) to simultaneously provide clamping force and absorb impacts/vibrations. They effectively extend track lifespan, reduce noise, and maintain gauge stability under train loads. These fasteners are widely applied in high-speed railways, heavy-haul lines, and urban rail transit systems, compatible with various sleeper materials and track structures including both ballasted and ballastless tracks. GNEE RAIL also supplies typical elastic fastener components like screw spikes, bolts, insulated gauge blocks , and spring washers.
Beyond offering complete rigid and elastic fastener products, GNEE RAIL provides diverse railway fasteners including fishplates, screw spikes, dog spikes, gauge rods, pads, and insulating pads compliant with various national standards.
