Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in railway fastening components. With over two decades of experience, we have supplied high-quality W-type elastic rail clip fixing assemblies to metro and urban rail transit projects worldwide. Our product is engineered to provide reliable rail fixation, excellent vibration damping, and long service life, meeting the demanding requirements of modern urban transit systems. As a factory-direct supplier, we offer competitive pricing and strict quality control, ensuring your project benefits from both performance and cost-effectiveness.
Product Features & Benefits
- Optimized W-Type Design: The unique W-shaped clip provides consistent clamping force, reducing rail displacement and ensuring stable track gauge.
- High Elasticity & Fatigue Resistance: Made from premium spring steel, the clip maintains elasticity over millions of cycles, minimizing maintenance frequency.
- Excellent Vibration & Noise Reduction: The elastic structure absorbs dynamic loads, lowering noise levels by up to 5-10 dB compared to rigid fastening systems.
- Corrosion Protection: Available with multiple anti-corrosion coatings (e.g., Dacromet, zinc flake, or black oxide) to withstand harsh environments, including tunnels and outdoor sections.
- Easy Installation & Replacement: Pre-assembled components simplify on-site installation, reducing labor time and costs. No special tools required.
- Compatibility: Designed to fit standard UIC60, 54E1, or 50kg/m rails and can be customized for other rail profiles upon request.
