In this blog post from Sree Metaliks Limited, we will be discussing the seven factors that make Fe-550 TMT Bars the best bet for any construction project. 

We will explore how these factors make Fe-550 TMT Bars a reliable, cost-effective, and safe choice for all of your reinforcing needs. With this information, you can make an informed decision about the type of steel bar that is right for you.


Fe-550 TMT bars are known for their superior strength and ability to withstand heavy loads. They are produced using a unique quenching and tempering process which gives them an even and uniform strength across the entire bar. 

This process also helps to increase their tensile strength, making them ideal for structures that require strong support such as bridges, high-rises, and dams. With superior resistance to bending and cracking, Fe-550 TMT bars are the perfect choice for building structures that require a high level of durability and dependability.


TMT steel bars offer excellent ductility, making them an ideal choice for construction projects. These bars are capable of being bent or stretched without breaking or cracking. 

Their ductility also allows them to be used in seismic zones and areas prone to earthquakes, as they can absorb the shocks without breaking. 

The TMT steel bars have an excellent bending radius, making them suitable for use in curved structures. As they are not brittle, they can be handled easily, further reducing the risk of damage during the installation process. Their excellent ductility also ensures that their dimensions remain constant over time, even when subjected to varying loads or stresses.

Tensile strength

The tensile strength of Fe-550 TMT bars is a measure of the maximum stress that can be applied before it fails or breaks. This strength is important for construction applications, as it determines the ability of a material to withstand external forces. Fe-550 TMT bars have excellent tensile strength, with a range between 500N/mm2 and 550N/mm2.

The increased strength makes them ideal for buildings that require higher seismic resistance. Fe-550 TMT bars also have superior elongation properties, meaning they are capable of withstanding large amounts of deformation before failure. These TMT steel bars allow them to absorb the energy generated by seismic waves and reduce the risk of structural collapse in the event of an earthquake.

Yield Strength

The yield strength of Fe-550 TMT bars from Sree Metaliks Limited is significantly high. This means that the bars can bear heavy loads and pressures without yielding. When compared to other similar products, the yield strength of Fe-550 TMT bars is considerably higher. 

This is a major factor that makes these bars the best choice for construction and building purposes. The high-strength steel bars have high fatigue strength and provide exceptional strength even after sustaining repeated impacts. 

Their yield strength also ensures that they are less susceptible to bending or breaking even under pressure. This makes them an ideal choice for use in earthquake-prone areas.


  1. Elongation is a measure of ductility and describes the amount of stretch or strain that a material can endure before it breaks.
  2. Fe 500D Grade TMT Bars from Sree Metaliks Limited have excellent elongation properties and can take on more stress before failure.
  3. With a minimum elongation of 16%, these bars have higher ductility compared to most other TMT bars in the market. 
  4. This elongation ability of the Fe 500D Grade TMT Bars helps in providing superior strength and durability during extreme temperatures and stressful situations. 
  5. The superior elongation properties of Fe-550 TMT bars provide flexibility and greater safety margins while using them in construction projects. 
  6. This high-strength steel helps reduce the risk of catastrophic failure which can cause immense damage and losses.
  7. The Fe-550 TMT bars also have better energy absorption capacity due to their excellent elongation properties. 

Thermal Stability

Thermal Stability

Fe-550 TMT bars from Sree Metaliks Limited are known for their excellent thermal stability. This makes them highly resistant to fire, heat, and other extreme temperature changes. These high-strength steel bars can handle higher temperatures without losing their strength or shape. 

They are also more resistant to cracking and other damages due to fire or extreme temperatures. This makes them a reliable choice when it comes to constructing buildings or structures that require protection from fires and other thermal shocks.


When it comes to the construction industry, it is essential to ensure that the materials used are strong, durable, and of the highest quality. Fe 500D Grade TMT Bars have been gaining popularity in recent times, thanks to their many advantages over other building materials.  From their strength and durability to their cost-effectiveness and eco-friendliness, Fe 500D Grade TMT Bars offer a multitude of benefits that make them the ideal choice for construction.


1. What is the maximum percentage of carbon allowed in fe500d bars?

The maximum percentage of carbon content allowed in fe500d bars is 0.25%, lower than the 0.30% in fe500 bars. This ensures greater strength, durability, and thermal stability for fe500d bars.

2. What does 550D stand for?

550D stands for the minimum yield stress in MPa, with ‘D’ denoting ductility – the amount of deformation a material can undergo before fracturing.

3. What is FE 550D grade steel?

FE 550D grade steel is a type of TMT steel bar that offers higher minimum yield strength and tensile strength than the 550 variant. It is a high-grade reinforced steel, designed to withstand greater stress while providing greater strength and durability.
