The SNS Passive Protection System is a flexible interception system composed of steel columns and supporting mesh structures. It absorbs rockfall impact energy to safeguard highways, railways, and buildings from falling rock hazards. The SNS Passive Protection System features a modular design that enables rapid on-site assembly, reducing construction complexity. Its open structure allows natural vegetation growth, minimizing ecological disruption while maintaining effective protection. With advanced anti-corrosion treatment, the system delivers long-term performance and reliability.

Product Advantages
Compared with rigid concrete retaining walls, the system eliminates large-scale foundation excavation, reducing material usage and construction volume by up to 60%.
Modular prefabricated components cut on-site construction time by 40%, lowering labor and equipment rental costs significantly.
The 30+ year anti-corrosion lifespan reduces the need for frequent replacements. For a 100-meter slope project, the total replacement and maintenance costs over 30 years are 50% lower than traditional rigid structures.
The open design avoids blocking natural drainage, eliminating additional drainage system construction expenses required for rigid retaining walls.
Application Scenarios
Highway and railway slope rockfall protection
Construction site safety barriers near mountainous areas
Mining area slope stabilization and debris flow interception
Mountain residential and tourist facility protection against falling rocks
FAQ
Q1: How does the system perform under extreme impact conditions?
A1: mesh structure absorbed the impact through controlled deformation, with only minor, repairable damage to individual components, avoiding complete system failure and costly replacement.
Q2: Does the system affect vegetation growth on slopes?
A2: The open mesh structure allows sunlight and water penetration. In a 5-year monitoring case in southwest China, native vegetation coverage on protected slopes increased by 35%, compared to a 70% vegetation loss rate on slopes protected by concrete retaining walls.
