Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998 – introduces our Passive SNS Flexible Protection System, specifically engineered for railway and highway cutting slope protection. This system combines high-strength steel wire mesh with a robust support structure to effectively intercept falling rocks, debris, and landslides, ensuring safety on critical transportation corridors. With easy installation and time-saving design, our passive flexible protection solution reduces labor costs and project duration while delivering reliable performance. Backed by our annual export value of US$5-10 million, we serve global markets including North America, South America, Europe, and Asia, providing OEM/ODM customization to meet diverse project requirements.
Key Features & Technical Specifications
- High-Tensile Steel Wire: Made from Q235/Q345 steel with tensile strength ≥1770 MPa, ensuring excellent impact resistance and durability.
- Flexible Mesh Structure: Diamond or square mesh openings (typically 100mm x 100mm to 200mm x 200mm) allow for deformation during impact, absorbing energy without fracturing.
- Corrosion Protection: Hot-dip galvanized or PVC coated finish provides long-term resistance to harsh weather, UV radiation, and chemical corrosion.
- Easy Installation: Pre-assembled panels with anchor bolts and support cables minimize on-site cutting and welding, reducing installation time by up to 40% compared to traditional rigid barriers.
- Customizable Dimensions: Panel sizes from 2m x 3m to 3m x 4m (or custom), wire diameter 2.0mm-4.0mm, with optional color coating (green, gray, etc.).
- Lightweight & Modular: Simple modular design allows quick transportation and assembly even in remote mountainous areas.

Advantages & Customer Benefits
- Time-Saving Installation: Pre-engineered components and simple anchoring system cut labor hours by 30-40% compared to conventional rigid barriers. No specialized equipment required.
- Low Maintenance: Flexible design accommodates ground movement and minor rockfalls without damage, reducing repair frequency and cost over the product lifecycle.
- Environmental Friendliness: The open mesh structure allows vegetation growth and water drainage, preserving natural slope stability and reducing ecological impact.
- High Impact Energy Absorption: Capable of absorbing up to 2000 kJ impact energy depending on system configuration, tested to meet international standards.
- Versatile Application: Suitable for both railway and highway cutting slopes, as well as mining areas, mountain roads, and construction sites.
- Long Service Life: With proper galvanization and coating, the system can last 15-20 years in moderate environments, with minimal degradation.

Frequently Asked Questions
1. How does the “passive” protection system differ from “active” systems?
Passive systems are installed at the slope base or along the slope to intercept falling rocks after they start moving, while active systems are attached to the slope surface to prevent detachment. Our passive SNS system is ideal for catch fences and rockfall barriers.
2. What is the maximum impact energy your system can handle?
Depending on the mesh size, wire diameter, and support structure, the system can absorb between 500 kJ and 2000 kJ. We can customize the design for higher energy levels upon request.
3. Can the system be installed on steep slopes (e.g., >60°)?
Yes, our anchor bolt and cable support system can be adapted to steep slopes. We provide detailed installation drawings and on-site technical support to ensure proper anchoring.
4. How long does installation typically take for a 100m length of protection?
With a standard crew of 5 workers, installation of a 100m-long, 3m-high system takes approximately 2-3 days, depending on ground conditions. This is 30-40% faster than traditional rigid concrete barriers.
5. What maintenance is required after installation?
Visual inspection every 6 months is recommended to check for any broken wires, loose anchors, or accumulated debris. The system is designed to be low maintenance; any damaged panels can be replaced individually.
6. Do you offer samples for testing?
Yes, we can provide small sample panels (e.g., 1m x 1m) for you to test tensile strength, corrosion resistance, and installation ease. Shipping cost is negotiable.
7. Are your products certified to international standards?
Our products comply with Chinese railway and highway standards (TB/T 3079-2016, JT/T 1130-2017). We can also produce according to EN 13438 or ASTM standards upon request. Certificates are available for review.
8. What is the typical lead time for a 500m² order?
For standard specifications, lead time is 15-20 working days. Custom orders may take 25-30 working days. We offer partial shipments to meet urgent project deadlines.
