Small,dense mesh effectively blocks thrown objects like stones and debris.High structural strength withstands impact.High wind load resistance is critical due to exposure on bridges.Demanding corrosion resistance needed for damp,vibrating environments,requiring heavy-duty treatment.Neat,aesthetic appearance harmonizes with the bridge structure.
Height is designed based on bridge height and protection needs,commonly 2.0m to 3.5m.Mesh is typically≤50mm or smaller.Material can be expanded metal(3.0mm-5.0mm thick)or small welded mesh.Frame and posts use large SHS or H-beam for rigidity.Connections use high-strength bolts with anti-loosening measures.
Used on urban viaducts,river/cross-sea bridges,railway bridges,overpasses.Prevents falling objects from injuring people or damaging vehicles/vessels below,especially critical on navigable waterways.Essential for public safety and social文明,also called"Bridge Safety Net"or"Debris Fence".
