Why Choose 75×6 mm GI Earthing Strip for Earthing?
The 75×6 mm GI earthing strip manufactured through hot dip galvanization offers significantly better durability than electroplated alternatives.
Electroplated strips typically have a thin zinc coating (5–25 microns), which can peel or degrade under soil pressure and environmental conditions.
In contrast, hot dip galvanization involves immersing steel in molten zinc at high temperatures, forming a strong metallurgical bond. This results in a thicker, more durable coating that resists corrosion for decades, even in harsh soil environments.
IS 3043 Compliance of 75×6 mm GI Earthing Strip
The 75×6 mm GI earthing strip is designed in accordance with IS 3043, ensuring it meets the required standards for earthing conductors in India.
Its 450 sq. mm cross-section allows it to safely carry fault currents without overheating or causing voltage instability. This makes it suitable for inspection approvals, consultant specifications, and insurance compliance.
