S.V. Metals & Extrusions Pvt. Ltd. (located in Greater Noida, Uttar Pradesh) is an ISO 9001-certified manufacturer, exporter, and supplier of electrical earthing equipment, cable trays, and structural steel accessories. Among its core portfolio, Galvanized Iron (GI) Earthing Strips stand out as a fundamental safety asset across commercial, industrial, and power infrastructure projects.
What is a GI Earthing Strip?
A GI Earthing Strip (or GI Earth Flat) is a flat strip of mild steel processed with a protective zinc coating via hot-dip galvanization. It forms a low-resistance path between an electrical system and the earth ground grid, safely dissipating fault currents, surge voltages, and lightning strikes into the ground.
Technical Specifications & Features SV Metals & Extrusions manufactures GI earthing strips designed in compliance with industry standards like IS 3043 (Code of Practice for Earthing) and IS 2629.
Key Specifications Feature Details Base Material High-Grade Mild Steel (MS) / Stainless Steel Surface Coating Hot-Dip Galvanized Zinc Finish Coating Thickness70 to 100+ Microns (Uniform, corrosion-resistant)Frequency Range50 Hz to 60 Hz Common Dimensions25x3 mm, 25x6 mm, 32x6 mm, 50x6 mm, 75x6 mm Length Options3 m, 6 m standard running strips or custom coils Tensile Strength370–520 MP a Key Benefits of GI Earthing Strips High Corrosion Resistance.
The hot-dip galvanizing process forms a metallurgical bond with the base metal. This protective zinc layer shields the steel against moisture, aggressive soil chemistry, and oxidation for long-term durability. High Fault Current Capacity Designed with flat surface profiles to maximize thermal surface area, GI strips quickly conduct heavy fault currents without overheating or compromising mechanical integrity.
Cost-Effective Grounding GI earthing strips deliver robust electrical performance at a fraction of the material cost of pure copper or copper-bonded strips, making them an economical choice for large-scale grounding grids. Robust Structural Strength Unlike soft copper, galvanized steel offers structural rigidity, resisting mechanical stress during subterranean burial, earth compaction, or physical impact.
Common Applications Substations & Power Distribution: Forms main earth mat grids, transformer grounding loops, and switchgear bonding rings. Industrial & Commercial Infrastructure: Connects heavy machinery, main distribution boards (MDBs), and cable tray networks. Solar Energy Parks: Grounding solar module mounting structures, central inverters, and array junction boxes against lightning strikes. Building Lightning Protection: Acts as down-conductors and perimeter earthing rings for high-rise buildings and commercial complexes.
