Utilizes Φ2.5-3.5mm hot-dip galvanized low-carbon steel wire (zinc coating thickness ≥80μm, compliant with GB/T 3081), with tensile strength of 300-500MPa and elongation ≥12%. Diamond hook braiding (mesh 50×50mm, angle 90°±3°), mesh thickness 14-20mm, width 0.8-2.0m, single sheet weight 15-30kg. The mesh body has no welding points, and local wire breakage does not affect overall stability. Salt spray test >1000 hours without red rust, suitable for mine environments with pH 4-10. Employs chromium-free passivation process (silane system), with galvanized wastewater reuse rate ≥90%. The mine-use galvanized iron wire protective diamond hook mesh provides reliable protection for coal mine tunnels through scientific material design and strict construction management. Under complex geological conditions, it can be combined with polymer materials and joint support techniques to further optimize support effectiveness and ensure safe mine production.
