0.62 kg/m is the unit weight of 10 mm dia, and you use the thumb rule for all other dia
unit weight per metre = d*d/162
where- d is dia of bar/rod in mm
TMT steel bars are produce from Carbon steel material(BILLETs/,INGOTS)Finish steel bar coming out of finishing stage of rolling mill is passed through devise where it is being passed through high pressure water jets to give the steel bars desire quality's 500/550Kg per cms.squre
the density of TMT R/F steel is 7850
TMT means Thermo mechanically treated steel its a new-generation-high-strength steel having superior properties such as weldability, strength, ductility and bendability meeting highest quality standards at international level..thanks Aarif
The standard length of TMT (Thermo-Mechanically Treated) bars can vary depending on the country and the applicable standards. In general, TMT bars are commonly available in standard lengths ranging from 12 meters (39.37 feet) to 15 meters (49.21 feet). However, it's important to note that TMT bars can also be custom-cut to specific lengths as per the requirements of a construction project. This allows for flexibility in adapting the bars to different structural designs and dimensions. When using TMT bars for construction purposes, it is recommended to refer to the applicable local standards and consult with suppliers or manufacturers to determine the specific standard lengths available in your region.
Lap Length is the length overlap of two rebars tied to extend the reinforcement length. Lap Length of about 50 times the diameter of the bar is considered safe. Let us understand the term “lap length” with an example: suppose there is a need to build a 200ft tall structure, say column. We know that for convenience of transportation, standard length manufactured are upto 12 metre only, hence to strengthen the structure overlapping of two or more bars are done side by side upto the design length. Reason for doing so is the required tension forces that is needed to transferred from one bar to the other. So if diameter of tmt is A then lap length will be 50A. If both diameter is same. Now coming to question, lap length of tmt 550 grade is usually done where minimum bending stress is encountered. We at Shree Ji Steel offer wide range of sizes and grade for various product range which can be checked from our website Shree Ji Steel Corporation.

Density = mass/volumeThe unit weight of steel is 7850 kg/m3volume of bar = (πd2/4)*Lhence mass = ((πd2/4)*L)*7850= ((3.14 *d2/4)*1)*7850 for unit length= 0.785*d2*7850= 6162.25 d2 if d is in metersor d2 /162 if d is in mm.By putting the value of diameter of rod, you can calculate the unit weight of any size tmt bar.

Formula for steel bar weight per meter = D2/162 where D is diameter of bar
meaning of 500 D in TMT bar
the weight should be change by the diameter of the rod.one rod length is thirteen meter and it should be measured in meter only. The formulae to find the weight of rod is d square /162 and you wil get unit weight then multiply it in length then u got a weight of the rod.
quenched and self temperedsame as TMT bars
diameter square of the bar. Divided by 162. gives W/1m length
The weight of a TMT (Thermo-Mechanically Treated) rod can be calculated using the formula: Weight (kg) = (Diameter² × Length × 0.00617). For a 20mm diameter rod that is 12 meters long, the weight would be approximately 15 kg per meter. Therefore, the total weight of a 12-meter length of 20mm TMT rod is about 180 kg.
