Product Description
The rail clips for railway, also known as rail track clips, rail fastening clips, or elastic rail clips, is an indispensable part of the railway track system. Usually installed between the sleeper and the rail, it provides support and buffering. Through its bending and deformation, it applies pressure to the track, ensuring a reliable connection between the rails, maintaining track integrity and stability, preventing rail displacement and dislocation, and guaranteeing the safe and smooth operation of the train.
Gnee has professional production equipment and a proficient technical team, enabling us to design and manufacture both standard and non – standard elastic rail clips to meet diverse customer needs. From raw material procurement to production and finished product application, we have a comprehensive and strict quality control system.

Non-standard rail clips: You provide railroad clip drawings, and we will produce according to your customized requirements.
As a reliable elastic rail clip supplier, rail clip distributor and stockist, Gnee is committed to providing the best quality products and services. Whether you are a rail fastener supplier or a rail engineering contractor, we have the right products for you. If you are looking for elastic rail clip for sale, Gnee Rails can be your first choice.
The rail track clips is suitable for the connection between the straight section of the standard gauge railway line, the radius R ≥ 300m, 50, 60kg/m rails and prestressed concrete sleepers, prestressed wide concrete sleepers and the overall roadbed;
When assembling the rail fastening clips, the nut torque is controlled at 80~120N.m in the straight section and the curved section with R>650m; the nut torque is controlled at 120~150N.m in the section with radius R≤650m.
The rail top height is adjusted by inserting the height adjustment pad, and the maximum height adjustment is 10mm.
The gauge adjustment adopts different types of gauge baffles and baffle seats. The adjustment amount of 50kg/rail is -8~+16mm, and the adjustment amount of 60kg/m rail is -8~+12mm.

Quality Control Of Gnee Rail Clips
Why Choose Our Rail Fastening Clips?
Qualifications and Systems
Gnee has always regarded “quality certainty” as the lifeline of the company. In the development of railway equipment, we deeply implement the ISO9001-2015 international quality management standard and have officially obtained a railway product manufacturing license.
Strict Quality Control
To ensure that every fastener delivered to our customers meets contractual requirements, Gnee has established a three-pronged quality assurance system:
Supplier Traceability System: A strict entry mechanism is implemented. All raw materials must be accompanied by chemical composition and mechanical performance reports and undergo sampling verification by our laboratory. Those that do not meet the standards are resolutely rejected.
Standardized Production Process: We possess advanced production lines for automated casting, rolling, and spring clip forming. From physical performance testing to salt spray corrosion testing, data is monitored in real time to ensure consistent quality.
Due to our deep understanding of multiple international standards such as ASTM, DIN, BS, and JIS, Gnee Rails products are capable of operating in the global railway market. We regularly undergo inspections by internationally recognized testing organizations such as SGS, BV, and ABS to ensure that every order accurately meets local route requirements.

Gnee Railway Track Clips Production Steps
The production process of Gnee railway track clips goes through the following steps:
Raw material preparation and testing: The main raw material of the railroad clip is spring steel, and sufficient spring steel material is prepared before production begins. Gnee usually tests whether the spring steel material has high strength, good elasticity and wear resistance.
Bending and cutting: The initial steel will go through the bending and cutting process, the steel will be cut into appropriate lengths according to the design requirements, and bent to form the basic shape of the railroad clip.
Heat treatment: After cutting and bending, the steel will be heat treated, mainly by heating to a high temperature and then cooling rapidly to improve the strength and elasticity of the steel.
Forming: The heat-treated steel will be fed into the forming equipment, and through mechanical processing and cold bending processes, it will eventually form a rail fastening clips with the desired shape and size.
Surface treatment: The rail track clip after forming may be surface treated, such as spraying anti-rust paint or hot-dip galvanizing, etc., to increase the corrosion resistance of the rail track clips.
Quality inspection: During the production process, the rail fastening clip will be regularly inspected for quality, including size, strength, elasticity, etc., to ensure that it meets the design and standard requirements.
Packaging and delivery: The elastic rail clips for railway that has passed the quality inspection will be packaged and prepared for delivery. Packaging usually takes into account the protection of the product during transportation and storage.
Environment: high cold | coastal salt spray | desert high temperature | other environments
