ERICO copper-bonded ground rods are the highest quality ground rods available today. We use a unique manufacturing process, which includes drawing the steel rod to size before the copper bonding process begins. This results in a straighter, harder steel core, making installation easier. ERICO uses a continuous electro-plating process over the steel core that results in a permanent molecular bond that provides decades of reliable performance. Our state-of-the-art ISO registered manufacturing facility provides a consistent, high-quality finished product that is used in millions of installations around the world.
