China Fiberglass GRP Glassfiber Glassfibre Composite Electirc Pole Cross Arm, Find details about China Fiberglass Crossarm, Glassfibre Crossarm from Fiberglass GRP Glassfiber Glassfibre Composite Electirc Pole Cross Arm
EDAO fiberglass composite cross arm is making by fiberglass material.
Our fiberglass composite crossarms. crossarms weigh significantly less than wood crossarms-with up to six times the strength. A closed-cell polyurethane foam fill provides lightweight, field drillable stability that also prevents moisture and contamination ingress. From impact-resistant endcaps to patented internal bushings.
