Volume x lbs/volume
Anybody know the formula to calculate the steel weight?

Hello there
If you steel shape is simple their answers are right but are your shape is not as a geometric shape I suggest you model it in SolidWorks software and go to the evaluate and find its weight with a high accuracy
First calculate the volume of the steel sheet. Note: If you are calculating the weight of circular steel reinforcement bar than calculate its volume by using this formula (πD^2/4) and then just multiply by the density of steel which is 7850 kg/m^3 and you will get the final weight of the steel.
Calculate Weight of Steel Bars
1. Estimation of Steel Reinforcement for slab,beam and column.
2. Weight of steel Flat bar = (Length x width x thickness) x 7850.
3. Example 1: Determine the unit weight of MS Flat bar of width 40mm and Thickness of 20mm.
4. Weight of steel bar = Volume of steel Bar x Density of steel.
- Weight of bar in kg/meter should be calculated as (d2 ÷ 162) where‘d’ is the diameter of bar in mm.
- ‘L’ for column main steel in footing should be considered as minimum 30cm/as specified.
- For bent up bar add 0.42d in straight length of bar where‘d’ is the clear depth of beam/slab.
- For cantilever, beam anchorage length for main steel should be 69D or length of cantilever whichever is greater.
Weight per meter of different dia of steel bar.
- 6 = 0.222 kg per meter
- 8 = 0.395 kg per meter
- 10 = 0.617 kg per meter
- 12 = 0.888 kg per meter
- 16 = 1.58 kg per meter
- 20 = 2.469 kg per meter
With help of this formula you can find any type of dia bar weight
(d2 ÷ 162)
Where
D = diameter of bar in mm.
Weight is a measure of the force of gravity pulling down on an object. It depends on the object's mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object's weight in Newtons (N) and m is the object's mass in kilograms.
