The document provides an overview of Thermo Mechanical Treatment (TMT) of steel bars, detailing its manufacturing process, usage in reinforced cement concrete (RCC), benefits, and cost-effectiveness compared to traditional steel. TMT bars are highly ductile, come in various grades like Fe 500D, and are essential for earthquake-resistant construction. Shyam Steel is highlighted as a leading manufacturer, emphasizing quality management and customer service.

1. Frequently Asked Questions on
Reinforcement Bar
(FAQ’s on TMT ReBar)

2. What is Thermo mechanical Treatment?
Once the molten iron passes through the basic oxygen
furnace and convert into steel. Thermo mechanical
Treatment (TMT) or Thermo mechanical processing is an
architectural process that unifies hardening and heat
treatment into a single process.
The quenching process makes the low carbon steel bars
softer in core and outer surface becomes hard with
prominent ribs. This process make the steel bar highly
ductile and make them ready for all type of construction
purpose.

3. What are the Usage of TMT Bar?
TMT bar is the main component in Reinforced Cement
Concrete (RCC). For all type of structures RCC ensures the
strength and longevity.
Be it your Home | Multi Storied Building | Commercial
Building | Power Plant | Bridges etc. TMT bars are highly
ductile therefore it can bend upto 180 degree without any
damage.
In order to secure all type of construction from natural
disaster such as earthquake you need to choose the best
quality TMT bar that provides the right combination of
Strength and Flexibility and protect your structure during an
earthquake.

4. What are the steps for Manufacturing TMT Bar?
TMT Bar Manufacturing has essential 3 steps:
Step 1 Step 2 Step 3
The hot rolled bar leaves
the finishing mill and
rapidly quenched by the
Thermex/Tempcore
process. The quenching
process converts the billets
layer into martensite and
shrink. Shrinkage process
pressurize the core and
helps to form the accurate
structure, the core remains
hot.
The bar leaves the quench
box with temperature
gradient. Gradually as the
temperature goes down
heat flows from bars centre
to its surface. Bars heat and
pressure correctly tempers
an intermediate ring of
martensite and bainite.
The final step is known as
Atmospheric cooling. Right
after the quenching
automatically tempers the
austenitic core to ferrite
and Pearlite on the cooling
bed which is having strong,
tough, tempered martensite
in the surface layer of the
bar, an intermediate layer of
martensite and bainite, and
a refined, tough and ductile
ferrite and pearlite core.

5. Benefit of using Corrosion Resistant Steel Bar?
Benefits of Corrosion Resistant Steel bars (CRS)are listed below
High Yield Strength
Highly Ductile and easily weldable
Longevity
Material Handling cost is nominal. No extra care needed.
Fabrication is easy with this corrosion resistant TMT bar
It can bend easily
No extra maintenance precaution needed
Highly recommended to use in Seismic Zones
In Seaside, highly humid areas, industrial use where saline
water/gaseous emission will come in contact only
Corrosion Resistant steel can be used

6. What is an Integrated Steel Plant?
A State of the Art Integrated Steel plant means it has the ability to
perform every step for manufacturing the steel. From processing the
raw material to final product that include:
 Raw Material Processing
 Iron Making with Blast Furnace
 Steel Making
 Continuous casting
 Producing Rolling Mills, Bars, wires etc.
An Integrated Steel plant must have DRI Unit, Electric Arc Furnace,
Continuous Billet Casting Unit, Rolling Mill.

7. Is TMT steel Bars are Cost Effective?
TMT Steel bars weight are lesser than Traditional Steel Bar. It is
essentially for it's tensile strength. Heavy weight products are stiff in
nature and easily cannot move or exchange the energy. Be it steel
bar or any other kind of material.
Steel TMT rods save upto 17% of steel over other steel rods. Steel
requirement idea for Fe 500D TMT Bar

Type of Structure
Steel requirement for
Fe 415
Steel requirement for
Fe 500D
Saving in Steel by
using Fe 500D
RCC Foundation 1 metric ton 0.83 metric ton 1.70 kg p/mt
Basically Higher Tensile Strength = Lesser Consumption of Steel

8. Why Fe 500D TMT Bar is best?
Fe 500d TMT bar are considered to be best because D = Elongation. As per
Indian Standard 1786 in 2008 this new standard has been introduced.
BIS (Bureau of Indian Standard) brought down the amount of Carbon,
Sulphur and Phosphorus values to increase its ductility.
In Reinforced Cement Concrete (RCC) Fe 500d provide high compressive
force. That is why it widely accepted for all type of construction
purposes.
Fe 500D TMT bar comes with the combination of Strength and Flexibility
that helps to protect your home during an earthquake.

9. Why Shyam Steel TMT Rebar is best for your Home?
Shyam Steel is the pioneer steel manufacturer and supplier in India. Over
60 years they are contributing to India’s growth. Shyam Steel’s
flexiSTRONG TMT Rebar is widely accepted nationwide. They adhere 5
main factors that helps to differentiate from others.
