1.At Shanghai Suyu Railway Material Co., Ltd, we specialize in the production and supply of superior elastic rail clips specifically designed for the railway industry. Crafted from premium raw materials, these rail clips boast exceptional tensile strength and unparalleled corrosion resistance. Precision-engineered for excellence, our products can be tailored to meet the specific demands of our clients, all at a competitive price point.
Renowned across the railway industry, our elastic rail clips offer outstanding clamping performance for rails, ensuring both efficiency and ease of installation.
With the expiration of patents from leading manufacturers like Pandrol and Vossloh, SUYU has partnered with esteemed quality manufacturers to deliver a cost-effective variety of elastic rail clips. These clips are suitable for various rail sections and applications, including the specialized SKL tension clamp.
Through stringent dimensional control and the utilization of premium spring steel, SUYU ensures that each elastic rail clip and other railway fastenings meet exacting customer specifications.
Our expertise allows us to produce elastic rail clips suitable for any toe load and axle load requirements, compatible with wooden, steel, or concrete sleepers. We offer clips in steel bar diameters ranging from 12mm to 20mm. For broad gauge lines, our flat-toe rail clips provide toe loads from 850kgf to 1100kgf. Additionally, we can meet any specific toe load and axle load needs for different types of sleepers.
Technical Specifications of the Elastic Rail Clip| Diameter | Weight (Kg) | Toe Load |
| 12mm | 0.18 | 200-400 |
| 14mm | 0.30 | 400-600 |
| 16mm | 044 | 500-700 |
| 18mm | 0.60 | 800-1000 |
| 20mm | 0.78 | 1100-1400 |
Our spring steel rail clips exhibit remarkable durability, enduring up to 5 million cycles of 9.1mm deflection without breaking.

2.As a leading manufacturer and exporter of SKL tension clamps, we ensure electric insulation of the rail on its support. Our tension clamps maintain the rail elastically in both vertical and transverse directions. The comprehensive fixing and supporting device includes a support table, projecting shoulders, a pad between the rail and support table, an insulating clip body, a bearing nose portion, at least one elastically yieldable strip, and the necessary fixing equipment.
Our boltable elastic rail clip provides robust and enduring clip strength. Ideal for rail construction with concrete sleepers, these clips range in diameter from 13mm to 15mm, including the SKL1, SKL2, SKL3, SKL12, SKL14, SKL21, SKL30 models, among others.
| Diameter | Type | Weight (Kg) |
| 13mm | SKL1 | 0.49 |
| 13mm | SKL3 | 0.53 |
| 13mm | SKL12 | 0.53 |
| 13mm | SKL14 | 0.505 |
