Rolling Margin of Steel Test Procedure
Now, to test the rolling margin of steel, we need to get a cut-length of 1 meter of a specific diameter of steel. The length of the samples should be at least 0.5 m or 500 mm. For example, let us take the cut-length of 16 mm diameter TMT bar and weigh it. We get actual weight of the cut-length steel as 1.56 Kg.

Create Long-lasting Landmarks with Ribbed TMT Bars
These machine crafted ribbed TMT bars allow for superior bonding with concrete that is essential for making landmarks last longer. ET TMT Bar rib geometry has the greatest effect in terms of bonding of reinforcement bar to the concrete. Proper geometrical configuration of ET TMT Bar ribs can prevent failure due to cyclic loadings (fatigue).

Understanding Rolling Process in Long Product Rolling Mill
If a mill rolls 80 % of the calendar year, that is 365 x 24 x 0.80 = 7008 hours. If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour. If the utilization can be improved by 1 %, the available rolling hours is 365 x 24 x 0.81 = 7096.6, creating 87.6 extra rolling hours.
