This formula can be used for calculating the weight of any TMT bar, provided you know its diameter and length, and it follows the steel used is of the specified standards. Let us calculate the weight of another bar whose diameter is 25 mm and length is 12 metres. This weight can be different by ± 7% when you actually get TMT bars. Now, let us calculate the weight of an 8 mm standard bar. Where W is the weight of the bar in kg, D is the diameter of the bar in mm, and L in the length of the bar in metres. The weight of 1 TMT bar can be calculated using the following formula. Then the mass of the bar per square metre will be. D is the diameter of the bar in metres and the mass will be calculated in kilograms.įor example, if the weight of the bar is 8 mm. To find out the mass of steel per metre square, the formula is D*D/162. it is the following for different sizes of bars. This variation is called weight tolerance, and it has to adhere to IS:1786-2008 standard law. In each bundle, the weight of the bars has to be consistent and only slight variations are permissible. The diameter can be 8 mm, 10 mm, 12 mm, 16 mm, 20 mm, 25 mm or 32 mm. Generally, the length of a standard TMT bar is 12 metres it is the diameter that varies. The number of TMT bars in your bundle will depend on the size of the TMT bars you are getting. He or she will also specify the size of the TMT bar. When you decide to buy TMT bars for the construction of your house, your architect or construction engineer will ask you to buy “bundles” of TMT bars. All reputable companies follow this standard for producing high-quality TMT bars. The BIS Standard IS-1786 from Bureau of Indian Standards (BIS) delineates specifications for high strength deformed steel bars and wires for concrete reinforcement. They lend structural integrity to buildings and help in preventing them from collapsing in the event of earthquakes. The construction of modern houses in India cannot be thought of without steel TMT bars.
