Gnee Steel (Tianjin) Co., Ltd. is one of the most reliable manufacturers and suppliers of type ii fastenering system in China, also supports customized service with low price. Please feel free to buy cheap type ii fastenering system made in China here from our factory.
Product Introduction
The type II rail fastening system consists of nuts, flat washers, type II elastic rail clamps, gauge baffles, rail plastic insulators, spikes, and rail pads.
In order to improve the strength and clamping force of the spring clip, high-quality spring steel 60SiCrVA is selected as the material of the type II spring clip, and the yield strength and tensile strength are increased by 42% and 36% respectively. The diameter of the spring clip is the same as that of the type I fastener, which is 13mm.

Type II Elastic Clip Fastening System Working Principle
- Each set of fasteners buckle pressure ≥ 20 kN;
- The longitudinal resistance of rails for each set of fasteners is not less than 9kN;
- The fastener system shall not be damaged after 3 million load cycles, and the gauge length shall be less than 6 mm;
- The left and right position adjustment of single steel rail: -8 ~ +6 mm, gauge adjustment: -16 ~ +12 mm; rail height adjustment: 10mm;
Rail Clip production process
- Select spring steels such as 60Si2CrA; ensure that the materials meet the standards through spectral analysis, tensile testing and metallographic testing.
- After heating, the mold is formed to control the size; after quenching and hardening, the performance is optimized by tempering to improve elasticity and fatigue resistance.
- Anti-corrosion such as hot-dip galvanizing is used; some are coated with anti-slip glue or anti-slip patterns to enhance the anti-corrosion and anti-loosening capabilities.
- Dimensional appearance and mechanical properties are tested; after passing the test, they are classified and packaged and stored in a suitable environment.
Product Application
Type II fasteners have the advantages of large buckle pressure, large strength and safety reserves, and small residual deformation, and are suitable for 60 kg/m rails and type II or III concrete sleepers. The elastic clip is an important component of the type II fastener system.
Conventional Main Line Railway
The trains on this type of line have high running density and heavy loads. The high-strength spring bars (made of 60Si2CrA) of the Type II fastener system can provide stable buckling pressure, ensure reliable connection between the rails and sleepers, and ensure safe and smooth operation of the train.
Heavy-duty freight railway
The Type II fastener system has a high strength safety reserve and can withstand the frequent rolling and huge impact force of heavy-loaded trains, reduce damage to track components, and extend the line maintenance cycle.
Special sections with high stability requirements
The Type II fastener system can effectively resist the vibration and lateral force generated by the passing of trains through precise structural design and reliable component performance, maintain the stability of the track geometry, and ensure driving safety.

Product Application
Protection first: ensure that the packaging can withstand vibration, impact and environmental erosion during transportation, and avoid damage to component performance (such as deformation of spring bars leading to attenuation of buckle pressure);
Convenient loading and unloading: unified packaging specifications facilitate mechanized loading and unloading, and improve logistics efficiency.
Packaging can also be customized according to customer requirements.
