Flat Bar Weight Per Meter, How To Calculate Flat Bar Weight, Flat Bar Weight Calculator
Flat bar weight calculation
The acknowledged density of mild steel is 7.85 g/cm3 (0.284 lbs/in3). Depending on the alloy elements added to manufactured specifications this can vary between 7.75 and 8.05 g/cm3 (0.280 and 0.291 lbs/in3)
The weight of flat bar is easily calculated. Simply multiply the appropriate alloy density by the length, width, and thickness of the required part (see worked examples below).
L / 1000
1 m / 1000
For an accurate calculation it is also important to allow for the rolling/drawn tolerances on section defined by the manufacturing specification.
The following charts are samples of some of the common thicknesses and sizes that are available.
