Features: 1. Resist corrosion better than galvanized rods. It has at least 30-year service life 2. Unique manufacturing process ensures uniform plating thickness 3. Reliable-the product is applicable in various soil moisture, temperature, ph value and varying earth resistivity construction condition. 4. Easy installation and low construction cost. 5. The special way of connecting adopted can deep-drive the rods up to 35 meters underground to meet low-resistance requirements in special occasions. 6. In comparison with the traditional way of using pure copper ground electrode, the cost of copper bond ground rods is much cheaper. 100 pcs/bundle, 500 pcs/pallet
