Mesh™ PE 11

Is an extruded carbon black polyethylene air-cushioned mesh.

Allter-Mesh™ PE 11 is a 11mm. thick extruded air-cushioned diamond shaped PE mesh for protecting coated pipelines from rock backfill when a thick sand collar is no option. Allter-Mesh™ PE 11 is also offering protection to coated pipelines from other abrasive sources caused by soil settlement and other geological movements. The material is absorbing high impact forces because of its air-cushioned properties and is, depending on the pipe diameter, longitudinally, spirally or circumferentially wrapped around the pipeline and secured by polymeric strapping.
