Application Function

Protection | Warning / Detection

ProtectaMesh™ HD rockshield mesh, manufactured by TYPAR, is a heavy duty pipeline mesh that protects pipeline coatings from rock backfill. ProtectaMesh HD rocksheild is essential for projects installed in rocky terrain, offering high compression strength and resistance to destruction during and after the backfill process.

ProtectaMesh HD rockshield is manufactured to a consistent thickness that provides full width protection, minimizing pipeline coating damange (holidays) and the resulting corrosion. The mesh is a three-dimensional bi-planar extruded diamond structured mesh made from a high-density polyethylene.

The open design allows for free movement of water around the pipe for cathodic protection. It is flexible, allowing for ease of installation at low temperatures and it is chemically inert, resisting rot.

ProtectaMesh HD rockshield offers better impact resistance, greater tensile strength and higher compression strength and is half the weight of the competition.

• Supplied in pads (cut pieces) or rolls for ease of installation
• Supplied in five or six foot widths

ProtectaMesh HD rockshield pipe protection mesh can be installed in three methods using either ‘Longitudinal wrapping’, ‘Latitudinal wrapping’ or ‘Spiral wrapping’ and secured by means of polypropylene strapping.
