TMT Bars

Primegold International Limited is one of India’s most renowned steel manufacturers, producing high-quality TMT bars. Primegold best TMT bars are reinforced with unique and innovative rib patterns that ensure high strength, ductility, and bendability while meeting international quality standards. These are commonly used to build bridges, flyovers, dams, industrial structures, high-rise buildings, and underground platforms, among other things.


TMT steel bars of exceptional quality are manufactured through a hot rolling process in which heated iron billets are continuously passed through rollers of decreasing diameters. These TMT Saria are passed through a water cooling system for thermomechanical treatment after they exit the last rolling mill. The technology is known as TEMPCORE technology, and it produces a hard yet ductile bar. The cooling system makes their outer surface cooler and harder, while the inner core remains warm and soft.


Prime Gold TMT steel bars (saria) are made using the same manufacturing process which provides a higher tensile strength. Higher elongation is one of the most significant characteristics of the Prime Gold TMT Saria. This improves the bend/re-bend properties, making them more resistant to natural disasters like earthquakes. Prime Gold steel bars have high thermal stability, making them safe in the event of a fire. The Prime Gold TMT bars’ unique ribbed design creates a powerful bond with the concrete or cement, providing additional stability and support to the building structure while also increasing its longevity and durability.


Our dedicated and skilled engineering and technical team, as well as metallurgists, are always searching for innovative ways to enable good, cost-effective steel bars and other products such as Structural steel, Cement, Stainless steel pipes and Stainless Steel doors.

Features and Applications

Primegold provides four grades of these steel bars: Fe-415, Fe-500, Fe-550, and Fe-600 (numbers represents the yield stress). TMT bars with a higher grade provide better quality and higher strength, making them suitable for large RCC structures such as roofs and floors. Balconies, fencing, and other decorative structures can all benefit from lower grade steel bars.


TMT bars are usually available in four grades in India. The yield stress is represented by the numbers Fe-450, Fe-500, Fe-550, and Fe-600. TMT steel bars manufactured with the best quality steel with higher yield stress (the highest grade) provide better quality and strength, resulting in a longer-lasting structure.

Lower-grade TMT bars are suitable for balconies, fencing, and other decorative structures, while higher-grade TMT steel bars (TMT Saria) are suitable for large RCC constructions such as roofs and floors.

Prime Gold steel bars are extremely flexible and bendable throughout their entire length. They can be moulded into any shape during construction by bending them up to a certain extent due to their flexibility, ensuring a modern living style.

TMT bars contain a lower percentage of carbon, which aids in achieving a high bending capacity. These bars are constructed in such a way that they have increased elasticity, allowing them to bend and re-bend with ease. They can be moulded into different shapes by bending them up to any extent due to their flexibility, ensuring a modern living style.

Our TMT bars provide high flexibility and earthquake resistance due to their favourable elongation and consistent property with much higher limits. These steel bars can actually elongate up to 18% longer than their original length without compromising the measurements, which saves money on construction making them the best TMT bar for construction.


Because of its elongation property, these best quality construction rods are completely earthquake resistant. There is a hard outer layer and a soft inner core to these steel bars. The outer layers of these bars are hard, with a softer inner core that helps to strengthen the structure and protect it from all types of natural disasters. This also means that these bars can absorb a lot of the energy that is released during disasters such as earthquakes. In fact, it can elongate up to 50% longer than its original length without compromising the measurements, saving time and money in the process.

Our TMT bars can be used in constructions where they will come into contact with water, such as plumbing areas, sanitary ware, salinity in groundwater, sewage drains, and so on, due to their corrosion resistance and moisture-resistant properties.


As our steel rods are treated with a corrosion-resistant chemical during the manufacturing process, these TMT Bars are also corrosion-resistant. This is one of the most important properties to have because these steel bars may be exposed to water for long periods of time during construction and will not rust due to its non-corrosive property.

Our TMT bars’ thermal resistance properties allow them to withstand any type of fire hazard while maintaining their strength due to their ability to withstand high temperatures.


TMT bars’ thermal resistance properties allow them to withstand any type of fire hazard because they can withstand a high degree of heat. These steel bars are known for their high thermal stability, which allows them to withstand high temperatures. These TMT steel bars can withstand temperatures of up to 600 degrees Celsius, which can be very useful in the event of a disaster, as fire safety is one of the main concerns for engineers and residents alike.

TMT Bars are more ductile in nature and are come in a choice of grades. TMT steel bars are stronger and more resilient than other types of reinforcement bars. The higher the grade, the more power they possess. One of the reasons why large construction projects look for high-grade TMT steel bars for building structures is this.

TMT Bars are distinguished by their delicate and soft ferrite-pearlite core, which allows them to withstand extreme weight loads.

Steel has the highest proportion of recycling of any material, with over 88 per cent. Without sacrificing quality, TMT steel bars can be recycled. Prime Gold is a proud steel (TMT Saria) manufacturer and distributor across India, and the steel industry is considered an eco-friendly industry.

TMT Bars Grades

In many construction projects, the Fe500 grade is considered a market standard for the best TMT bar. Fe500D and Fe 500S, two variations of Fe500, are also likely options that provide greater seismic consistency and durability.

  • Fe 500 bars can be used in a variety of residential, commercial, and multi-story construction projects.
  • They have higher ductility and toughness than Fe 415, which is specifically designed to provide stabilisation and load resistance in high-rise projects.
  • These steel bars are used in areas where there is a lot of seismic activity and there are a lot of sudden loads.

Fe 550 grade steel bars can be used in a variety of large-scale projects due to their increased tensile strength.


  • These are used in the development of industrial and massive infrastructure projects, such as brides, industrial projects, and structures with high load-bearing capacities.
  • These bars have a particularly strong impact in the coastline, marine, and underground environments.

Fe 600 is one of the most durable TMT steel bar grades used in the construction of heavy-duty infrastructure projects such as bridges and marine facilities. They provide higher tensile strength, generally lower consumption, and reduce steel congestion in the reinforcement.


  • Expressways, metro projects, plants, towers, commercial properties, and industrial zones are all built with Fe 600.
  • Widely used in large-scale projects where load bearing, durability, and corrosion resistance are more important.


Steel reinforcement bars (TMT Saria) are an excellent choice for today’s construction projects. TMT Steel Bar has a variety of properties, including Yield Strength, Highly Ductile, Earthquake Resistance, Corrosion Resistance, and Fire Resistance.


Thermex Cooling Technology is used to create high-quality TMT rods. These bars are made using two processes: curing and self tempering. As a result, the cores become ferrite and crystalline, with a martensite outer surface that is highly flexible and solid. This is not a parallel pairing. TMT steel bars become extremely bendable due to their exceptional Yield Tensile properties.


These rods are ribbed for added strength. It evenly distributes the weight across the TMT bar. The ribs improve the grip on the concrete. During the construction process, it reduces the risk of sliding. The use of the TMT Bar helps a structure last longer. Maintenance requirements are slightly reduced due to the high weldability and adhesion, resulting in cost reduction.

Reinforced Ribbed Bars

Double rows of crossing ribs are used in Reinforced Steel Bars. It is evenly dispersed along the length and enables efficient concrete bonding.


Nominal Cross-sectional Area 

A cross-sectional zone that is similar in size to the area of a round bar of the same nominal diameter.


Longitudinal Rib

It has a constant and regular distension that corresponds to the steel-reinforced bars vertical.


Rib Transverse

It is a rib on the TMT steel bars exterior that isn’t a longitudinal rib.
