Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998 with an annual export value of US$5 million to US$10 million. Our Passive SNS Flexible Protection System (12mm wire rope, 200x200mm mesh, hot dip galvanized, 100kN load capacity) is specifically engineered for debris flow mitigation. Combining decades of metal wire expertise with advanced engineering, this system offers reliable, long-lasting protection for slopes, highways, and infrastructure. Its flexible design absorbs high-energy impacts while maintaining structural integrity, making it a cost-effective solution for challenging terrains.
Product Highlights
- High Load Capacity: Rated at 100 kN, ideal for severe debris flow events.
- Robust Wire Rope: 12 mm diameter, hot dip galvanized for superior corrosion resistance.
- Standard Mesh Opening: 200 x 200 mm – balances retention and drainage.
- Flexible System: Energy dissipation components reduce peak forces.
- Passive Design: No moving parts, minimal maintenance required.
Technical Specifications
| Component | Parameter |
| Wire Rope Diameter | 12 mm |
| Mesh Opening (nominal) | 200 x 200 mm |
| Load Capacity | 100 kN |
| Surface Treatment | Hot Dip Galvanized (HDG) |
| Steel Grade | High-tensile steel (optional) |
| Energy Dissipation | Brake rings or friction brakes (customizable) |
| Installation Type | Ground anchors, posts, and support cables |
Detailed Features & Benefits
- Enhanced Durability: Hot dip galvanized coating (≥85 μm) ensures 20+ years of service in harsh environments, including coastal or acidic soil conditions.
- Optimal Debris Retention: The 200x200mm mesh opening traps large debris while allowing water and fine sediment to pass through, reducing hydrostatic pressure behind the barrier.
- Flexible yet Strong: The 12mm wire rope, combined with energy absorbers, can deform under impact to dissipate energy without rupturing. This passive system remains effective even after multiple small events.
- Quick Installation: Pre-assembled panels and standard components reduce on-site labor and time. Our factory supports customization to match specific topography.
- Low Maintenance: No hydraulic or mechanical parts – only periodic visual inspection recommended. The galvanized finish resists rust and corrosion.
- Scalable Design: Available in various heights and lengths. The 100kN load capacity can be upgraded by adding extra support ropes or using thicker mesh (customizable).
Ideal Applications
- Debris flow barriers along mountain roads and railways
- Slope protection for mining sites and quarries
- Riverbank erosion control
- Protection of residential areas in landslide-prone zones
- Infrastructure projects (bridges, pipelines, power lines)
Why Choose Anping Boli?
With over 25 years of manufacturing experience, we export to markets across North America, South America, Europe, Asia, Africa, and Oceania. Our factory in Hengshui, Hebei, uses advanced wire drawing and weaving machinery, ensuring consistent quality. We have shipped hundreds of passive protection systems globally, with many clients reordering after successful installations. Our team provides technical drawings, load calculations, and installation guidance upon request.
Trust & Reliability
Every system undergoes strict quality control: wire rope tensile testing, galvanizing thickness measurement, and assembly inspection. We can provide sample panels for testing. Our annual export value of US$5-10 million reflects our commitment to quality and customer satisfaction. Contact us today for a quotation or technical consultation.
Frequently Asked Questions
1. What is the lifespan of this passive SNS system?
Under normal conditions, the hot dip galvanized coating provides 20+ years of corrosion protection. The steel rope core can last even longer if inspected regularly.
2. Can the mesh size be customized?
Yes, we offer custom mesh openings (e.g., 150x150mm, 250x250mm) and wire rope diameters. Please contact us with your requirements.
3. Is the 100kN load capacity sufficient for heavy debris flows?
The 100kN rating is the nominal working load. For extreme events, you can specify a higher capacity (e.g., 150kN) by adding extra ropes or using thicker mesh. Our engineers can help design accordingly.
4. How is the system delivered?
Typically shipped in bundles: wire rope panels, support cables, anchors, and energy absorbers. We pack them in containers for FOB Tianjin/Qingdao/Shanghai ports.
5. What tools are needed for installation?
Basic tools: tensioning equipment, wrenches, and possibly a small crane or excavator for lifting. Detailed installation manual is provided.
6. Do you provide samples?
Yes, sample panels (e.g., 1m x 1m) are available upon request. Freight charges apply.
7. Is this system suitable for rockfall as well?
Yes, it can be used for rockfall protection. However, for very high-energy rockfalls, consider our heavy-duty SNS series with thicker ropes or double layers.
8. How do I choose the right height and length?
Please provide the slope angle, debris flow volume, and site photos. We can then recommend a standard or custom design.
