Copperbond Earth Rods, deep driven, usually provide the most cost effective earth system.
They are made from a low carbon, high tensile strength (600n/mm² minimum) steel core with a coating of molecular bonded 99.9% pure electrolytic copper.
Extendable type rods have a rolled thread (UNC2A) at each end.
Material: Pure copper molecularly bonded on to a steel core.
Made from austenitic steel to British standards.
The stainless steel rod is similar to copper rods but are more anodic than copper and are useful where galvanic corrosion is possible.
These rods have a tapped hole at each end which allows them to be joined together by means of a coupling dowel.
Can be supplied in different grades if required.
Material: Stainless Steel.
