Rockshield Mesh is a heavy-duty plastic mesh designed to protect pipeline coatings from rocky backfills. When pipelines are buried, the surrounding soil often contains sharp rocks, stones, and debris that can puncture or scrape the protective anti-corrosion coating of the pipe. By wrapping the pipe with Rockshield Mesh, operators create a robust cushioning layer that absorbs the impact and pressure of these rocks during the backfilling process and subsequent soil movement. This ensures the long-term integrity of the pipeline infrastructure by preventing direct physical damage to the underlying pipe fusion bonded epoxy or bitumen coating.
Beyond standard pipeline installations, Rockshield Mesh is frequently used in challenging terrains like rocky mountainsides, river crossings, and offshore landfalls where mechanical protection is critical. The mesh is highly flexible, allowing it to conform easily to various pipe diameters, bends, and irregular joint shapes without cracking. Its open mesh structure allows water to pass through freely, which is essential for the proper functioning of cathodic protection systems that prevent electrochemical corrosion. Because it is chemically inert, the mesh does not rot or degrade when buried underground, ensuring continuous protection over decades of pipeline operation.
