Question
What is mean by Rolling Margin Of Steel????
 Question Submitted By :: Civil-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
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%

# 2
Rolling margin is the difference between the theoretical
and actual weight of steel. This is because of the die
which is used for casting of rebars. Over a period of time
the shape of die changes and as a result the diameter of
the steel bar also changes which results in difference in
unit weight of steel.
The size of the die is kept small and as a result rolling
margin is negative in the initial stage of production,
there after it is more of less close to theoretical weight
and then the size of die increases which results in rolling
margin on positive side.
If you purchase steel from same supplier over a period of
time the rolling margin would be adjusted and you are not
at a loss.
