RockArmour™ Mesh
ROCKARMOUR™ MESH is a pipeline protection material composed of extruded mesh manufactured from a proprietary polyethylene formulation. RockArmour Mesh is inert to biological degradation and resists naturally encountered chemicals, alkalis, and acids. It protects pipeline coatings during installation and backfill operations without interfering with cathodic protection.
