1. Ground Rod copper thickness: >=0.254mm 2. Resistivity: <=0.05ohm/mm 3. Tensile strength: >=500N/mm 4. Material: Q235 Professional manufacture of copper ground rod, and using high-quality low-carbon steel core Q235, with plated 99.9% pure copper production process, thus ensuring the copper layer and steel core molecular link between the permanent. With good conductivity, corrosion resistance and higher tensile strength.Our main specification as follow:
