Introducing the SNS Flexible Slope Protection System – a robust solution engineered for mining and quarry operations to prevent rockfalls and mitigate slope instability. Manufactured by Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with an annual export value of US$5-10 million, this system combines 500kJ energy absorption, 16mm anchor diameter, and 10m drop height capacity to deliver reliable protection in the most demanding environments. Our flexible barriers are designed to absorb dynamic impact forces while maintaining structural integrity, significantly reducing downtime and repair costs for your operations.
With over 25 years of experience in wire mesh production, we have supplied thousands of slope protection systems to markets across North America, South America, Europe, Africa, Oceania, and Asia. Our products are tested for durability and performance, ensuring long service life even under harsh weather and geological conditions. The SNS system is customizable to fit various slope angles, rockfall risks, and site-specific requirements, making it a versatile choice for both open-pit mines and quarry faces.
Product Features & Technical Specifications
- High Energy Absorption (500kJ): The system can absorb up to 500 kilojoules of impact energy, effectively stopping falling rocks of significant mass and velocity. This capacity is ideal for deep open-pit mines and high-slope quarries.
- 16mm Anchor System: Heavy-duty anchors with 16mm diameter provide strong foundation support, ensuring the barrier remains stable even under repeated impacts. Anchors are hot-dip galvanized for corrosion resistance.
- 10m Drop Height Protection: Designed to intercept rocks falling from heights up to 10 meters, the flexible netting system dissipates energy through controlled deformation, minimizing damage to the barrier and underlying infrastructure.
- Flexible Structure: The SNS (Synthetic Netting System) uses high-tensile steel wire ropes and mesh panels that flex under load, distributing impact forces over a wide area. This reduces stress concentration and prevents rupture.
- Corrosion Resistance: All components are hot-dip galvanized or coated with anti-corrosion materials, suitable for acidic mine environments and coastal areas with high humidity.
- Easy Installation & Maintenance: Modular design allows quick assembly on-site without heavy machinery. Maintenance is minimal, with only periodic inspection of anchors and tensioning required.
- Customizable Dimensions: Available in various heights, widths, and mesh sizes to match specific slope configurations. Options include double-twisted mesh or ring net systems.

Key Benefits for Your Operations
- Enhanced Safety: Prevents falling rocks from reaching workers, equipment, and haul roads, reducing accident risks and insurance costs.
- Reduced Downtime: Quick installation and low maintenance mean less interruption to mining or quarrying activities.
- Cost-Effective: Compared to rigid rockfall barriers, flexible systems are more economical in material and installation, yet provide higher energy absorption.
- Environmental Compatibility: The flexible mesh allows vegetation growth through the net, blending with natural landscapes and reducing visual impact.
- Versatile Use: Suitable for both temporary and permanent slope protection, and can be integrated with other geotechnical measures like soil nails or shotcrete.

Frequently Asked Questions
-
What is the maximum rockfall energy the system can handle?
The system is rated for 500 kJ energy absorption, which is suitable for most mining and quarry applications. For higher energy requirements, we offer custom designs with additional capacity. -
How long does installation typically take?
Installation time depends on the slope area and complexity. A standard 100m² barrier can be installed by a 5-person crew within 2-3 days, including anchor drilling and tensioning. -
Can the system be used on steep slopes?
Yes, it is designed for slopes up to 70° (or steeper with special modifications). The flexible net conforms to irregular terrain, making it ideal for rugged mining sites. -
What maintenance is required?
Periodic visual inspections every 6 months are recommended. Check for loose anchors, tears in the mesh, or corrosion. Replacement of damaged sections is straightforward and does not require specialized tools. -
Is the system environmentally friendly?
Absolutely. The open mesh structure allows vegetation to grow through, promoting ecosystem restoration. The galvanized coating is non-toxic and safe for the surrounding environment. -
Do you offer custom sizes?
Yes, we can customize panel dimensions, wire diameter, mesh opening, and anchor spacing to meet your site-specific needs. Contact our sales team with your requirements. -
What is the warranty period?
We offer a standard 1-year warranty against manufacturing defects. Extended warranty options are available upon request.
