Grid Guard Rock Shield – Standard Duty

Description

The Grid Guard Rock Shield is an extruded polyethylene mesh material engineered to provide superior protection for coated metal pipelines during trenching, backfilling, and long-term operation. Designed to act as a durable barrier, Grid Guard prevents damage from rocks, soil movement, and other sharp objects while ensuring coatings remain intact and pipelines maintain long-term integrity. Unlike rigid protection systems, this flexible and lightweight shield is easy to install, adapts to irregular trench conditions, and maintains its cushioning performance even in cold temperatures. Importantly, it has no dielectric properties, ensuring that cathodic protection systems remain fully effective.

Product Benefits

• Ultimate Pipeline Protection – Safeguards coated pipe surfaces during backfilling and against shifting soils.
• Impact Resistance – Tested to ASTM G-14 standards, providing superior protection against coating damage on fusion bond epoxy, coal tar enamel, and extruded polyethylene coatings.
• Flexible & Lightweight – Easy to handle and install in the field, while conforming to trench shapes and irregular surfaces.
• Durability in Harsh Environments – Retains performance in low temperatures without loss of flexibility or cushioning.
• Compatible with CP Systems – No dielectric interference ensures cathodic protection remains effective.
• Cost-Effective Protection – Reduces the risk of costly coating repairs or premature pipeline failures.

Typical Applications

• The Grid Guard Rock Shield is ideally suited for:
• Protecting coated pipelines during trenching and backfilling
• Shielding coatings from soil movement and shifting loads
• Acting as a barrier against rocks, debris, and sharp objects in buried environments
• Long-term integrity protection for underground pipelines, fittings, flanges, and girth welds

Technical Specifications

• Material: Extruded Polyethylene
• Thickness: 0.16 inch (ASTM D-1777)
• Compressive Strength: 25,000 psf (ASTM D-1621)

Why Choose Grid Guard Rock Shield?

When pipeline coating integrity is critical, the Grid Guard Rock Shield provides proven, ASTM-tested protection against impact, abrasion, and soil-related hazards.
