| Protectamesh HD ( pipeline rock guard shield is a |
|
thick diamond mesh extruded from
low density polyethylene designed to protect pipeline coatings. It cushions against the impact of rocks which could puncture the coating during backfilling and cause corrosion. • Low-temperature flexibility for ease of handling |
| • Chemically inert |
| • Apertures allow water flow |
|
• High impact resistance to ASTM
G*3 MOD • High tensile strength |
|
• Up to half the weight of
alternatives • Can be supplied in rolls or in pads (cut pieces) for easy installation |
