DEEP EARTH GROUNDING

Installing ground rods beyond 10 foot deep presents several problems. Sectional rods must be used (typically 10-12 foot long) and coupled together to achieve the desired depth. The coupler is a larger diameter than the rod and therefore forms a hole bigger than the rod itself.Design and Development of Automatic Bending Machine Our Bending machine is typically used for making I-Bolts to support various truss structures as well as electric rods and cell towers and it is also used to bend stirrups for fabrication purpose.
