What is weight of 40x10mm gi flat per meter?

The weight of a 40x10 mm galvanized iron (GI) flat bar can be calculated using the formula: weight (kg/m) = (width × thickness × length × density) / 1,000,000. For a 40 mm width and 10 mm thickness, the weight per meter is approximately 3.1 kg/m, assuming a density of around 7,850 kg/m³ for steel. Therefore, a 40x10 mm GI flat bar weighs roughly 3.1 kg per meter.
