Copper Earthing Materials - Rods, Tapes & Bars

Austral Wright Metals supplies a comprehensive range of copper earthing materials designed to provide safe, reliable grounding for electrical installations across Australia.

Copper is the industry’s preferred choice for earthing because it delivers exceptional electrical conductivity, superior corrosion resistance, and outstanding durability. These properties ensure dependable performance and long service life, even in demanding environments.

Effective earthing systems protect people, equipment, and infrastructure by safely dissipating fault currents and lightning energy into the ground. Austral Wright Metals supports projects across industrial, commercial, and renewable sectors with quality copper products that meet Australian and International standards.

Copper’s physical and electrical properties make it the most effective and economical material for grounding systems:

• Low resistivity (1.68 × 10?? ?·m) for excellent current flow.
• High conductivity up to 101% IACS  (? 5.96 × 10? S/m) ensures low resistance and stable earthing performance.
• Excellent corrosion resistance in most soil conditions.
• Strength and ductility for easy installation and long-term reliability.  Easy to bend.
• Fully recyclable and sustainable for modern infrastructure.

Austral Wright Metals sources copper earthing materials manufactured to strict quality standards, ensuring consistent performance and compliance.

When the higher strengths are needed for your earthing solutions, marine grade 316 stainless steel can be used.

Stainless steels physical and electrical properties make it an economical replacement for copper in these situations.

• Resistivity (? 0.76 × 10?? ?·m)
• High conductivity (? 1.28 × 106 S/m)

Solid Copper Earth Rods

• Made entirely of high-purity copper (C11000).
• Provides the lowest possible resistance and long service life.
• Recommended for areas requiring maximum corrosion resistance.

Copper Earthing Tape

Q. What are copper earthing materials used for?

A: Copper earthing rods and tape keep people safe, protect equipment, and ensure electrical systems work correctly by sending excess electricity into the ground.

Which is better copper or aluminium for earthing?

A: Copper is preferred because it has superior electrical conductivity and corrosion resistance in soil, leading to a longer service life.

Q: How long do copper earthing systems last?
A: Properly installed copper earthing systems can last for 40 to 80 years or more, depending on soil conditions and maintenance practices.

Q: What’s the difference between a copper-bonded and a solid copper rod?
A: Copper-bonded rods feature a steel core coated with copper for strength and cost efficiency, while solid copper rods are pure copper for maximum conductivity and corrosion resistance.

Q: Are copper earthing materials compliant with Australian standards?
A: Yes. Austral Wright Metals supplies materials compliant with AS/NZS 1566 and AS/NZS 1567, and relevant international standards.

Is there an alternate to copper for earthing systems needing high strength?
A: Yes. Austral Wright Metals can supply earthing material in marine grade 316 stainless steel.
