How to Calculate Structural Steel Weights
- 1). Measure the length of the steel beam with the tape measure and note the measurement, such as 20 feet.
- 2). Measure the height of the steel beam and note the measurement, such as 6 inches or 0.5 feet.
- 3). Measure the width of the steel beam and note the measurement, such as 6 inches or 0.5 feet.
- 4). Multiply the length by the height by the width to calculate the volume of the beam. In this example, this equation looks like (20 x 0.5 x 0.5), for a result of 5 cubic feet.
- 5). Multiply the cubic feet of the steel beam by the density of steel. This equation looks like (5 x 490) for a result of 2,450 lbs. This is the weight of the structural steel beam.
