A safe electrical system starts below the ground. Every switchboard, transformer, solar plant, telecom tower and lightning protection system depends on an earthing path that can carry fault current away quickly and safely. GI Earth Rods are one of the most widely used and cost-effective ways to build that path. At SG Power Products Pvt. Ltd., we design and manufacture galvanized iron earthing rods that combine mechanical strength, corrosion resistance and dependable conductivity, so your installation stays protected for years.
As one of the trusted GI Earth Rods Manufacturers and Suppliers in India, SG Power supplies ready-to-install rods with palm and clamp terminations for residential, commercial, industrial, railway, metro, DISCOM and renewable energy projects across the country.
GI Earth Rods (also called GI earthing rods, galvanized iron earth rods or GI grounding rods) are solid steel rods coated with a protective layer of zinc through hot-dip galvanizing. The rod is driven or placed vertically into the soil and connected to the electrical installation through an earthing conductor, such as a GI strip or wire.
When a fault occurs, for example when a live conductor touches a metal enclosure, the fault current flows through the earthing conductor into the rod and dissipates into the surrounding soil. This keeps the voltage on exposed metal parts at a safe level, helps protective devices such as MCBs, RCCBs and fuses trip quickly, and protects people and equipment from electric shock, fire and surge damage.
The zinc coating is what makes a GI rod practical for underground use. Zinc corrodes far more slowly than bare steel, and it also protects the steel core sacrificially, so the rod keeps working even if the surface gets scratched during installation.
SG Power is a leading manufacturer of earthing electrodes, GI electrodes, backfill compounds, earth pit covers, lightning protection equipment, welding powder, servo voltage stabilizers and rectifier plants. Our head office is in Sector 62, Noida (Uttar Pradesh), and we supply earthing solutions to customers throughout India.
What separates SG Power from many other GI Earth Rods manufacturers and suppliers is that we offer a complete, single-source earthing solution. You can source the rod, the terminal, the backfill compound, the earth pit cover and the lightning arrester from one company, with matched specifications and one point of accountability. This is why our products are trusted by railway, metro, DISCOM, renewable energy and engineering service projects.
Our GI earthing rods are marketed under the TRUESAFE™ brand and are designed in line with IS 3043 (the Indian Standard Code of Practice for Earthing). They are tested and verified under UL and CPRI certification standards for consistent quality and safety.
We manufacture GI Earth Rods in two main termination styles, so you can choose the connection method that suits your site and earthing conductor.
The palm-type GI earth rod has a flat palm terminal at the top with pre-drilled holes (10 mm × 4 holes). The flat surface gives a large contact area for bolting GI strips, copper flats or cable lugs, which results in a low-resistance, tight joint. Palm-type rods are ideal for substations, panels, DG sets, transformers and any installation where several conductors need to be connected to one electrode.

The clamp-type GI earth rod is supplied with a T-Type welded terminal clamp for a secure and vibration-resistant electrical connection. Because the terminal is welded to the rod, there is no risk of the clamp slipping or loosening over time. This version is well suited to building earthing, lightning protection down-conductor terminations, telecom shelters and solar structures.

Quality earthing depends on quality materials. Every SG Power GI earth rod goes through a controlled manufacturing process:
Raw material selection: E250 grade structural steel is used for the core for good strength and drivability.
Cutting and terminal fabrication: Rods are cut to length, and the palm or T-type clamp is fabricated and welded with consistent weld quality.
Surface preparation: Rods are degreased, pickled and fluxed so the zinc bonds evenly to the steel.
Hot-dip galvanizing: The rod is dipped in molten zinc to form a metallurgically bonded, uniform protective coating.
Inspection and testing: Coating thickness, adhesion, uniformity, dimensions and weld strength are checked before dispatch.
This disciplined process is the reason customers looking for reliable GI Earth Rods manufacturers and suppliers keep returning to SG Power for repeat orders.
Excellent corrosion resistance: The hot-dip zinc coating protects the steel core from moisture and soil chemicals, giving the rod a long service life.
High mechanical strength: The steel core resists bending during installation, even in hard or gravelly soil.
Cost-effective: GI rods cost significantly less than solid copper or copper-bonded rods, which makes them practical for large projects with many earth pits.
Ready-to-connect terminals: Factory-fitted palm or welded clamp terminals save site time and give reliable joints.
Standards-based design: Designed according to IS 3043 and verified under UL & CPRI standards.
Compatible with backfill compounds: Works with SG Power earth enhancement compounds to lower and stabilize earth resistance.
Low maintenance: Once installed correctly, GI rods need only periodic resistance checks.

| Factor | GI Earth Rods | Copper Bonded Earth Rods |
|---|---|---|
| Core material | Steel with zinc coating | Steel with copper coating |
| Cost | Lower – budget-friendly | Higher |
| Corrosion resistance | Good in normal soil | Very high, better in highly corrosive soil |
| Mechanical strength | High | High |
| Best suited for | Buildings, industries, utilities, large multi-pit projects | Critical installations and very aggressive soils |
For most residential, commercial and industrial projects with normal soil conditions, GI earth rods offer the best balance of performance and price. Our engineers can help you decide between GI and copper bonded earth rods based on soil resistivity and fault current.
Test the soil: Measure soil resistivity to decide the number and length of rods required.
Prepare the pit: Auger or dig a pit of the recommended size and depth.
Place the rod: Drive or place the GI earth rod vertically so the terminal stays accessible at the top.
Add backfill: Fill around the rod with earth enhancement compound to improve conductivity and retain moisture.
Connect the conductor: Bolt the GI strip or cable to the palm or clamp terminal and tighten securely.
Fit an earth pit cover: Protect the connection with a durable earth pit cover for easy inspection.
Measure resistance: Test earth resistance with an earth tester and record it for future maintenance.
