What is weight of 100x25mm ms box?

To calculate the weight of a 100x25 mm mild steel (MS) box section, you need the volume and the density of mild steel. The density of mild steel is approximately 7850 kg/m³. The weight can be calculated using the formula: weight = volume × density. For precise weight, the wall thickness of the box section is also needed; however, a rough estimate for a standard hollow section can be obtained by calculating the volume of the material used.
