Rolling Margin is the deviation of actual unit weight to
that of Standard unit weight as per IS Standards.
Rolling Margin is calculated as :
Sectional weight = Weight of Steel Bars dia wise / length
of the bars.
As per IS Standards unit weight of the Bars is calculated
as dia x dia / 162
Rolling Margin is deviation of actual sectional weight to
that of IS Standard unit weight.
Standard Rolling Margin for different dia reinforcement
bars used for construction purposes:
8mm to 10mm +- 7%
12mm to 16mm +- 5%
20mm & Above +- 3%
