In order to connect the equipments like Diesel Generators, Transformers and equipment to Earthing Electrodes which are likely to carry fault current above 3kA, Galvanised Iron Strip ( also called GI Strip) Conductors are used to connect equipment to earthing to be able to carry safely the fault current till the time interrupting device like MCB, MCCB or Air Circuit Breaker operate and isolate the faulty equipment.

GI strip weight Calculator -Or GI strip Weight Calculation Formula
To calculate wieght per Kg of a GI strip, pl use this folrmula:
Weight in Kg/meter = Width (mm)x Thickness X 0.0084 ( with allowances for error 7.5% )
How to Calculate gi strip 25×3 mm price ?
Step 1 – Calculate weight in Kg/meter of the 25×3 mm GI strip
weight in Kg/meter = 25x3x0.0084 = 0.630 kg /meter
The prices of GI strip in per kg = say Rs 100/kg ( Rate changes day to day being a commodity, so pl check prices of the day)
So the GI strip 25×3 mm price per meter = 0.630 x100 = Rs 63/meter
