Product Description
Passive Rockfall Barrier System Overview
The passive rockfall barrier system is installed at the base of mountains or slopes to effectively reduce and block falling rocks, stones, and debris. This protective system minimizes the impact of rockfalls and safeguards people, infrastructure, and property from potential damage.
System Types and Specifications
Steel Wire Rope Net System
Constructed with high-tensile steel wire rope nets, decompression rings, support ropes, sewing ropes, and steel columns. This system provides exceptional strength with energy absorption capacity up to 750 kJ, making it suitable for both active and passive rockfall protection applications.
Steel Ring Net System
Manufactured from high-quality hot-dipped galvanized wire formed into interlocking circles. The steel ring net system offers superior energy absorption capacity up to 2000 kJ, with configurations including steel ring nets, support ropes, anchor ropes, sewing ropes, and metal columns.
