The Importance of the Correct Bending Method and Choosing the Proper Mandrel Size for Rebar Bending

Why Are TMT Bars Important in Construction?

TMT bars, or Thermo-Mechanically Treated bars, are the backbone of modern construction. Known for their high yield strength, ductility, and earthquake resistance, they ensure long-lasting durability of structures. The process of bending these bars must be done precisely to maintain their mechanical properties.

Why Is the Correct Bending Method Important?

Bending TMT bars requires utmost precision. If done improperly, it can lead to cracks, weakening the structure.

• AMBA Shakti SD TMT Bars are produced using no twist straight mill rolling, ensuring no distortion and uniform bonding with cement.

• CNC notching enhances uniformity, while controlled raw material ensures consistent performance.

  
  

Thus, correct bending helps retain the super ductility of the bars, essential for earthquake-resistant structures.

Why Is Choosing the Proper Mandrel Size Critical?

The mandrel size determines the inner diameter of the bend. Using the wrong size can damage the bar and compromise its load-bearing capacity.

• For AMBA Shakti SD TMT Bars, the right mandrel size ensures smooth bending without cracks.

• Their high-pass life HSS rolls and fully automated mill production deliver better finish, durability, and uniformity post-bending.
