What are the grades of TMT bars?
TMT bar manufacturers in India manufacture four different grades of TMT bars – Fe-415, Fe-500, Fe-550, and Fe-600. The numbers indicate the level of stress that must be applied to deform it and higher the grade, the stronger and superior the bar is. The grades are given according to their strength and rigidity.
Which grade TMT bar is best?
Fe 600 grade is the strongest and ultimate grade of TMT steel that you will get from any steel manufacturer.
What is rate of 8 mm steel?
8mm TMT BAR at Rs 40/kilogram | TMT Bars | ID: 14911365512.
What is meant by Fe 415 steel?
The abbreviation Fe represents ferrous material for example iron, from which the reinforcement steel bars are fabricated. The number 415 shows that the yield strength of steel is 415 N/mm². Fe 415 is fundamentally one of the numerous accessible levels of TMT bars/rebars utilized for the development of RCC structures.
What is TMT full form?
TMT stands for Thermo Mechanically Treated steel. QUOTE. Thermo mechanically treated steel known as TMT steel can be described as a new-generation-high-strength steel having superior properties such as weldability, strength, ductility and bendability meeting highest quality standards at international level.
What is the weight of 1 bar?
Round Bar Weight Table
| Diameter (inch) | Lbs Per Inch | Lbs Per 12 Ft. Bar |
|---|---|---|
| 1 | 0.220 | 32.040 |
| 1/64 | 0.230 | 33.000 |
| 1/16 | 0.250 | 36.170 |
| 3/32 | 0.270 | 38.330 |
Which mm rod is used for roof?
bars or 8 mm or 10 mm tor-steel bars are generally used. They are provided at the bottom of the slab allowing minimum cover of 25 mm of concrete.
How do you calculate rods?
If we put 1 meter length for each diameter of steel bar in the formula then we will get the unit weight.
- 6 mm ø bar = 6² x 1/162 = 0.222 kg/m.
- 8 mm ø bar = 8² x 1/162 = 0.395 kg/m.
- 10mm ø bar = 10² x 1/162 = 0.617 kg/m.
- 12mm ø bar = 12² x 1/162 = 0.888 kg/m.
- 16mm ø bar = 16² x 1/162 = 1.580 kg/m.
What is Fe415 and fe500?
– Fe-415 denotes that a force of 415 N/sq.mm. is required to deform the TMT bar, whereas Fe-500 denotes that a force of 500 N/sq.mm is required to deform the TMT bar. – The difference in the strength between Fe-415 and Fe-500 grades therefore is 20%.
What is Fe 410 grade steel?
Grade 410 stainless steels are general-purpose martensitic stainless steels containing 11.5% chromium, which provide good corrosion resistance properties. However, the corrosion resistance of grade 410 steels can be further enhanced by a series of processes such as hardening, tempering and polishing.
What is Fe500 in steel?
In the Fe 500 & Fe 500D the term “Fe” denotes Iron,”500” stands for the minimum yield stress in N/mm2 and the letter “D” denotes that such bars have higher values of ductility (higher UTS/YS & % Elongation). These bars have lower percentages of sulphur and phosphorus which are harmful for steels used in construction.
Which steel bar is best?
Top 10 best TMT bars brand in India are – 1) Tata tmt bar grade Fe500, 2) Tata tiscon SD TMT bar, 3) Jindal Panther TMT bar, 4) Sail TMT bar, 5) Kamdhenu TMT bar, 6) SAIL and ViZag CRM TMT bar, 7) Tata TMT bar, 8) SRMB steel tmt bar, 9) JSW steel tmt, 10) Shyam Steel tmt bar, etc.
How many 12mm iron rods make a ton?
Mathematical calculation such as number of pieces of 12mm Rods in one ton = 1000kg/weight of one piece of 12mm Rod, 1000kg ÷ 10.667kg = 94 pieces. Therefore 94 No’s of 12 meter of 12mm Rod or steel bar makes a ton.
