They are highly resistant to corrosion, and because the steel used has a very high tensile strength, they can be driven by power hammers to great depths. One common misconception is that the dia of the rod has a drastic effect on lowering earth resistance.
This is not true! Use the most economical rod that soil conditions will allow you to drive. Coupling threads are formed by a rolling process to ensure thread strength and to maintain the durability. The university used thread rolling process raises the surface of the rod. Thus thread dia is greater than rod dia.

'M-Flex' Solid Copper Grounding Rods are made from
pure EC Copper. These rods are designed for use where extremely
high corrosion resistance and exceptionally long life is required.
They are ideally used in application where soil condition are very
aggressive, such as soil with high salt content.
