❓ Frequently Asked Questions About TMT Calculator
What is a TMT bar?
TMT (Thermo-Mechanically Treated) bars are high-strength reinforcement steel bars used in construction. They have a tough outer core and a softer inner core, providing excellent strength and ductility.
How is TMT bar weight calculated?
The standard formula is Weight (kg) = (Diameter² / 162) × Length (meters). For example, a 12mm bar weighs 0.888 kg per meter.
What is the standard length of TMT bars?
Standard TMT bars come in lengths of 12 meters, though custom lengths are available upon request.
Why is the formula D²/162 used?
This formula is derived from steel density (7850 kg/m³). The constant 162 comes from (π/4 × 7850) / 1,000,000 = 0.006165, and its reciprocal is approximately 162.
What is the difference between TMT and normal steel?
TMT bars undergo a special thermo-mechanical treatment process that gives them higher yield strength, better ductility, and superior corrosion resistance compared to normal mild steel bars.
