We can explain what you should look at when buying:
b) GL-00085inserted joint rods are connected by driving into each other: one end of the rod has a blind hole and the other rod is inserted into it with its tapered end forward. A sealing sleeve is included to proved the reliability of the connection. It is not required to buy additional sleeves, tip or guide heads to prepare the inserted joint ground rod for connection.
a) Due to the fact that ZZ-001-065 threaded ground rods do not have a tapered end, a special component — a steel starting tip - is used to simplify the process of driving the rod into the soil.
Threaded ground rods are mounted using a vibratory jackhammer. An SDS-max steel driving head adapted for jackhammers is available in our catalog for this purpose. Using the vibratory jackhammer and the reliable threaded connection you can drive the ground electrode into the soil to a depth of 40 meters (read more about the quality of materials).
b) As indicated above, inserted joint rods have a tapered end that allows an electrode to be driven in the soil without using any additional components.
Typically, inserted joint rod-based ground electrodes are assembled using a hand sledgehammer. Use a driving head installed in the blind hole of the inserted joint rod during assembly.
However, you can also assemble inserted joint rods with a vibratory jackhammer. For this purpose, you will need a tip for the hammer driving head.
And these are all the differences. It should be noted that both threaded and inserted joint rods have high performance, allowing ground electrodes on their basis to be used virtually in all types of soil *.
