What is rolling margin in reinforcement steel | structural steel Rolling margin in reinforcement steel is percentage of deviation in Sectional weight of Reinforcement steel allowable as per IS codes. Reinforcement steel is extruded from a mould which is made for a particular size eg 8mm Dia. When the mould is brand new, the sectional weight of 8mm steel extruded through mould would exact as per IS standard of lower than that. ie 0.395Kg per Metre or lesser. Mould gets little bigger after certain period of time or after certain quantity of production is taken from a particular mould. Now same 8mm dia bars extruded from the same mould will have more weight per Metre say 0.400Kg per Metre instead of 0.395 as per IS. That is more mass per Metre/Length is required for same length. This deviation in weight is defined in IS codes for different dia which is as under :- Allowable deviation in rolling margin in reinforcement steel as per Indian standards 8mm to 10mm +/- 7% 12mm to 16mm+/- 5%. 20mm and above+/-3%. Rolling Margin is calculated as under :- Total Weight of Bars (Dia wise ) / Total Running Metre of Bars = Actual Sectional Weight of bars. Compare sectional weight with Standard IS Weight.

What is rolling margin in reinforcement steel | structural steel

Rolling margin in reinforcement steel is percentage of deviation in Sectional weight of

Reinforcement steel allowable as per IS codes. Reinforcement steel is extruded from a mould

which is made for a particular size eg 8mm Dia. When the mould is brand new, the sectional

weight of 8mm steel extruded through mould would exact as per IS standard of lower than that.

ie 0.395Kg per Metre or lesser. Mould gets little bigger after certain period of time or after certain

quantity of production is taken from a particular mould. Now same 8mm dia bars extruded from

the same mould will have more weight per Metre say 0.400Kg per Metre instead of 0.395 as per

IS. That is more mass per Metre/Length is required for same length. This deviation in weight is

defined in IS codes for different dia which is as under :-

Allowable deviation in rolling margin in reinforcement steel as per Indian standards8mm to 10mm +/- 7%

12mm to 16mm+/- 5%.

20mm and above+/-3%.

Rolling Margin is calculated as under :-

Total Weight of Bars (Dia wise ) / Total Running Metre of Bars = Actual Sectional Weight of bars.

Compare sectional weight with Standard IS Weight.
