The twin helixs earth screw anchor is welded to two spiral plate square poles.
The dimensions of the axis are 1-3/8 inches, while the size of the plate is 6 "8", and 10 "12" depends on the soft or hard surface soil.
On hard soil, we have to use 6 "8", so it's easy to nail the soil in.But for soft soil, we need to choose a larger spiral plate size.
The surface of the earth's driving screw is painting.
