WHY ARE TMT BARS DESIGNED WITH RIBS

The modern-day construction industry requires steel reinforcement bars, also known as TMT bars, to form the foundation of structures.

Have you ever seen those circular bumps on the surface of a TMT bar and are curious what that is all about? Thermo-Mechanically Treated steel bars (TMT bars) are an essential reinforcement element for concrete structures. These TMT steel bars have a ringed cross-section and can only give reinforcement when there is ample anchor between the concrete and the steel. To better this bonding, modern-day TMT bars along with limbs are known as Ribs.

Types of RIBS in TMT Bars –

  • Reinforced steel Bars Ribs

Reinforced steel bars have double rows of crosswise ribs distributed uniformly and the entire length is covered. It ensures efficient bonding with the concrete. Steel bars that are circular or usually have semi-circular cross-sections can be used in RCC (reinforcement of cement concrete). Steel-reinforced cement concrete structures (RCC) are commonly called ‘rebars’.

The Reinforced steel Bar is mainly of 4 types – 

  1. Hot Rolled Deformed Steel Bars
  2. Cold Worked Steel Bars
  3. Mild Steel Plain Bars
  4. Prestressing Steel Bars
  • Ribbed reinforced Bars

A ribbed steel bar is a type of deformed, high-strength steel that is made by controlled cold-twisting of the hot-rolled bar. This bar has projections on its outer edge known as ribs that’s why the name Ribbed Steel Bar.

  • Transverse Rib

Transverse ribs are distances running corresponding to one another and at a certain predefined point to the bar pivot which add support or make the holding solid. It is present on the outer surface of the TMT bar other than a longitudinal rib to strengthen it.  

  • Longitudinal Rib

Longitudinal ribs help in balance during the moving action of TMT steel bars. Inside each line, cross-over ribs are likewise equally circulated all over the TMT Bar to provide structure and balance to it. Basically, A similar protrusion that runs parallel to the vertical axis of the TMT steel bar is known as the longitudinal rib.   

Why are Ribs Important in TMT Bars?

  • MAKES TMT BARS EARTHQUAKE RESISTANCE

Ribs give extra strength between TMT Bars and Concrete. The structures become strong and for its yield strength work with bond concrete more that helps to withstand the structure during an earthquake or flood. That is why JBG HEXA TMT bars are Earthquake-resistant.

  • BETTER GRIP WITH RIBS

Ribs give a better grip on concrete. It reduces the possibility of slipping during construction. The Ribs in TMT Bar make the construction structure longer-lasting. The maintenance turns out to be very cost-effective for JBG HEXA premium TMT bars Because of their excellent grip.

  • INCREASES BONDING

Ribs give great strength to the structures. JBG HEXA TMT Bars are specially designed bars to help in excellent bonding as well as fighting against natural disasters. It strengthens the bonding between TMT bars and concrete for a better result.

JBG HEXA TMT Bars are Highly Ductile, Earthquake Resistant, Corrosion Resistant, and Fire Resistant.  This combination is considered exemplary. TMT Bars are highly ductile with extreme Yield Strength and Elongation. JBG HEXA premium TMT bars are manufactured by using Thermax Technology and are considered the best choice for construction.
