### What is rolling margin for reinforced steel and how it is calculated?

Rolling margin is percentage of diviation 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 e.g 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.i.e. 0.395Kg per Metre or lessor.Mould gets little bigger after certain period of time or after certain quantity of production…

### Rolling margin of steel rod which is used for construction?

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…

### What is the unit weight of rebar 8mm?

0.395 kgs = unit wt of 8 mm dia rebar There is another way of calculating the specific weight (or unit weight) of a rebar. Especially for those who are interested of rebars less than 10mm of dia. the way is to calculate it mathematically knowing that the density of steel rebars is 7851 Kg/m3. 8mm rebar ==> Unit weight [Kg/m] = Cross-Sectional Area [m2] x Density [kg/m3] = (Pi)x(radios)2 x 7851 kg/m3 = 0.395…

### What is the unit weight of TOR STEEL bar 28mm dia?

I have a method to unit weights of tor steel bars, 28mm Diameter- 4.835kg/m it does not matter size of bar, if bars diameter say X then square it, X2 then divide by 162.163, X2 162.163 Example , 28mm 282 162.163 (162.162162162- 162 recurring decimal)/162.162 bar =4.834641688kg/m approximate to 3 decimal =4.835kg/m try other examples,for 8mm, 10mm,12mm,16mm,20mm,24mm u will answer 8mm dia : 0.395 kg/m ,10mm dia : 0.617 kg/m ,12mm dia : 0.888 kg/m…

### Formula to find weight of a steel rod whose dimension are 8mm diameter 1meter length?

Calculation for weight of steel. Volume of Steel Rod(Vs)= (pi*d*d)/4*l.where pi= 3.14 d Diameter of bra= 8 mm in this case l length of bar = 1 m so, Volume of steel = ((3.14*0.008*0.008)/4)*1 =0.00005024 m3 Weight of steel = volume of steel * unit weight of steel Unit weight of steel = 7850 kg/m3 Weight of steel = 0.00005024* 7850 = 0.394 kg/m

### What is the unit weight of 8mm dia tor steel bar kg per ft?

8mm - 0.120 kg/ft 10mm - 0.189 kg/ft 12mm - 0.269 kg/ft 16mm - 0.483 kg/ft 20mm - 0.755 kg/ft 25mm - 1.173 kg/ft ++++ I'm glad I don't buy steel from you! I don't know what "tor steel" is, but no reputable materials stockist or engineering designer would mix two totally different scales like that. If diameter is in millimetres and mass in kilogrammes, lengths should be in metres, not feet. The question assumes…
