Hot Dip Galvanized Earthing Strip

What is a Hot Dip Galvanized Earthing Strip?

A Hot Dip Galvanized Earthing Strip is a steel strip coated with a thick layer of zinc by immersing it in molten zinc. The galvanization process creates a protective coating that prevents rust and corrosion, making the strip suitable for underground and outdoor grounding applications.

HDG earthing strips are used to connect earth electrodes, earthing pits, equipment, structures, and grounding grids, ensuring effective dissipation of electrical fault currents into the earth.
