The most economical choice is to replace dead soft annealed (DSA) copper with DSA copper clad steel for grounding applications (down-pole and mats). Below are a few of the major advantages:
Life Equivalent to copper in corrosion resistance
Fatigue Resistance Superior to annealed copper
Handling Flexible and manageable like copper, yet more robust and durable than dead soft annealed copper
Mechanical Higher mechanical strengths minimize physical damage during installation and service
Weight Lighter than copper by 8.5% for equivalent sizes
Theft Resistance Zero scrap value
