The ET Corrosion Resistant Steel Gold Bar is an innovative offering from ET TMT. CRS – or Corrosion resistant steel bars are highly corrosion resistant construction Best TMT Bars. They reduce the rate of corrosion due to their properties and hence greatly enhance the life span of the structure.

The ET CRS Gold bars have been subjected to corrosion evaluation as per ASTM standards which include the Alternate Immersion test, Atmospheric Exposure Test, Sulphur Dioxide test, Potentio Dynamic Test and have proven resistance to corrosion

The ET CRS Gold bars are best suited for use in areas where the structure is likely to be constantly exposed to water or moisture, such as in a marine environment, in places with brackish ground water, for areas with saline sub-oil or high rainfall and humidity. They are also ideal for use in Seismic zones.

Advantages of ET CRS Gold bars:

  • ET TMT CRS Gold bars are Made from High quality BIS certified produced in-house.
  • They have a longer life due to superior pitting corrosion resistance.
  • These bars can be bent and rebent around very small mandrels.
  • The bars also possess High yield strength coupled with ductility and bendability.
  • Each of these bars passes through stringent quality control through NABL accredited in-house physical and chemical laboratories
  • ET TMT boasts of the single largest production capacity of the Best TMT Bars for construction in Gujarat.

Making of the ET TMT CRS Gold bar.

At ET TMT, captively produced billets safeguard that only high-quality input is available for production of CRS bars. The captive billets are produced using high quality sponge iron which is also produced in-house at ET TMT. 

The steel made here is produced with an accurately calibrated chemical composition. The chemistry of each billet is precisely controlled by using Spectrometer testing. To increase the corrosion resistance property of the ET TMT CRS Gold bars, elements like copper, phosphorus and chromium are added in the correct proportion to make the steel resistant to corrosion from inside i.e. at grain boundary. 

The quenching technology is also used after rolling to ensure that there is a presence of self-tempered layer over martensitic layer. This step imparts high strength and high ductility to the bars. The distribution of corrosion resistant elements is homogeneous from the core to the surface. The high strength of the bars ensures that they are highly resistant to applied force. The high ductility ensures that ET TMT CRS Gold bars can undergo permanent changes in shape without rupturing.

Method of producing ET TMT CRS Gold bars:

At ET steel, the method of building is of prime importance. We employ the world’s most advanced standards.

Steel produced from sponge iron is of the highest quality hence ET TMT bars are produced from iron ore at the ET TMT’S world class facility following a stringent and streamlined production process.

The iron ore is smelted in a blast furnace or a sponge iron kiln. The steel from the smelted iron ore is then sent to the steel melting shop from where it reaches the ladle refining furnace. In the ladle refining surface, impurities like phosphorus and sulphur are removed. The purified steel is then forwarded to the billet caster where the billets are shaped and these billets are sent to the rolling mill. 

Here the billets are rolled into bars to give them the grooves for superior bonding capacity with concrete and once the rolling is complete the next step is the Thermex quenching system. 

It is in the Thermex quenching system that the bars are finally tempered using temperature-controlled water systems.  Here the bars are cooled and tempered by the water flow and they develop the variable structure having a soft inner core and a hard-outer core. This leads to higher force resistance while maintaining ductility.

Once the bars have cooled, they are checked for defects and irregularities in the physical and chemical labs where both the physical structure as well as the chemical properties of the bars are examined to ensure that only the bars that meet all the quality checks reach the consumer.

Following the lab tests, the bars are certified and then moved on to the storage and dispatch where they are stored or distributed as per need.

ET TMT CRS Gold bars are available in two variants, ET TMT CRS Gold 500 and ET TMT CRS Gold 500 D.

ET TMT Cut Bend Bars

ET TMT CUT and BEND TMT Bars are customised TMT bars also known as ET TMT C&B TMT bars, using the revolutionary cut and bend technology. 

ET C&B TMT bars meet the specified standards, provide safety and longevity to concrete structures and ensure the complete safety of a structure. 

Advantages of ET CUT BEND BARS:

Made from the world’s finest machines, Electrotherm (India) Ltd. has the best 100% automatic machines procured from Italian manufacturer Schnell to manufacture all kinds of steel bar designs and variants from 8 mm to 36 mm bars.

-Eliminates the storage and Stock problems 

Material is ordered and supplied as per the need and is made available to the construction site for assembling thereby eliminating the shortage, overstocking and storage problems.

Making of the ET TMT CUT and BEND bars:

The ET TMT CUT and BEND bars are manufactured at the state-of-the-art facility of Electrotherm Steel using the Stirrup Technology.

Cut and Bend bars are prefabricated bars customised as per requirement and exact specifications. This ensures that only the required quantity and size of the bars are provided to the customer. The ET TMT CUT and BEND bars are ready to use bars.

In order to manufacture the bar at ET TMT, captively produced billets are used to ensure that only high-quality input is available for production of CUT and BEND bars. The captive billets are produced using steel from the best quality Iron Ore. This steel is also produced in-house at ET TMT. The steel made here is produced with a precisely calibrated chemical composition. 

The chemistry of each billet is precision controlled by using Spectrometer testing. To increase the corrosion resistance property of the ET TMT C&B bars, elements like copper, phosphorus and chromium are added in the desired proportion to ensure a high corrosion resistance property in the steel bars right from inside i.e. at grain boundary. 

The quenching technology of tempering steel bars is also used after running the bars through the rolling mill to ensure that there is a presence of self-tempered layer over martensitic layer. The application of this process imparts high force resistant strength and high ductility to the bars. 

The distribution of corrosion resistant elements is also homogeneous from the core to the surface. The superior strength of the bars ensures that they offer high resistance to applied force. The high ductility ensures that ET TMT CUT and BEND bars can easily be cut and modified to precision to suit the specific needs of a structure without displaying wear and tear.

Method of producing steel for ET TMT C&B bars

ET TMT C&B Steel bars at Electrotherm are made using high quality sponge iron or iron ore. Good quality of iron ore is used in Blast Furnace of 128 m3 and 63 m3, directly reduced Iron (DRI) kiln of 250 and 350 TPD. 100% iron ore is used and no scrap is used in the melting process. After melting the DRI from kilns and hot metal from the Blast Furnace in Induction Furnaces, a unique and patented ERF-ELdFOSTM metallurgical process is applied to dephosphorus the steel in the ladle and desulphurised the steel in Electrotherm Ladle Refining Furnace (ERF) specially to meet the stringent phosphorus and sulphur requirement of FE 500 D grade of TMT bars. Multistage testing of steel chemistry using the spectrometer ensures adherence to chemistry in close tolerance.

In the Ladle Refining Furnace, metal is also homogenised, alloying elements are added and controlled in a very controlled range, dissolved gases in the steel are lowered through mild purging of inert gases and any undesirable inclusions are removed or altered chemically to ensure the high quality of steel for manufacturing ET TMT C&B bars. 

This refined steel is cast into billets of required sizes in a closed environment to have further control of gases and other inclusions. Molten pig iron (hot metal) from the Blast Furnace and Direct Reduced Iron (DRI) from the kiln is the key to make superior quality ET TMT C&B bars.

TMT bars are free from tramp elements like Cu, V, Ni, Cr etc. unlike steel used at other conventional manufacturing units where scrap is used and there is no control on impurities.

After refining the steel in LRF, it is rolled according to the required size in a state-of-the-art Rolling Mill and thermomechanically treated in a Standard Quenching Box. Highly atomised quenching, self-tempering and atmospheric cooling ensures that TMT bars have superior mechanical properties in strength, weldability, ductility and bendability meeting or exceeding quality standards. Quality control is highly stringent through NABL accredited labs and equipment.

ET TMT Epoxy Coated Bars

Epoxy coated TMT bar, one of the best TMT bars in India, are a highly corrosion resistant variant of steel bars which are protected by Fusion Bonded Epoxy coating. Commonly referred to as FBE coating it is widely used to protect concrete reinforcement bars, steel pipes, piping connections etc. used in construction.

FBE coatings are in the form of dry powder at normal atmospheric temperature. The powder is applied electrostatically to the surface of cleaned hot steel bars and cured to form a protective film after undergoing various chemical processes. 

The epoxy coated bars last longer due to the protective film which prevents corrosive elements from coming into contact with the surface of the steel and thereby contribute to raising the quality of construction.

Advantages of Epoxy Coated bars:

The superior anti-corrosive property of epoxy coating extends the life of TMT bars and leads to much lower lifecycle costs over time.

The epoxy coated bar needs very low maintenance which helps to lower the labour costs significantly. These bars are also highly flexible and may be bent on a special mandrel during production to avoid causing damage to the epoxy coating.

One of the primary concerns of highway construction companies at present is to make environment friendly structures. Epoxy causes no harm to the environment and is a sustainable solution in this direction.

As per studies, structures built with epoxy last longer than similar structures made with black steel.

This is also a cost-effective solution as a very little is added to the overall cost of the structure to add epoxy coated bars.

This is a factory-based technique and therefore a greater degree of stringent quality checks may be applied to the process. The thickness of the coating also remains uniform through-out.

The epoxy coating has excellent adhesion and it form a lasting bond with the surface of the steel TMT bars.

The Fusion bonded Epoxy Coating acts as an insulator for electrochemical cells and creates a barrier of protection, sealing off the steel, preventing entry of chloride ions through it, which can cause further corrosion. 

Process of manufacturing Epoxy TMT Steel Bars:

 The epoxy coating is added to the steel bar under a rigorous procedure to ensure the best results with the following steps. 

First the Surface of the TMT bar is cleaned to remove oil and grease using shot blast cleaning method.  This type of cleaning technique is highly effective in removing rust, scales, slats and other undesirable elements from the surface of the steel. The resulting industrial grade surface is clean and a rough surface finish, ideal for application of the epoxy.

The TMT bars are then pre-heated using different methods. Of these the most efficient heating method is that of induction heating. For induction heating TMT bars are passed through a high frequency alternating current along with a magnetic field which heats according to the required FBE coating application temperature which is usually 225°C to 245°C.

Next the FBE powder is placed on the fluidisation bed and the heated TMT bar is passed through the coating booth fitted with electrostatic epoxy spray guns and the dry powder is sprayed on the heated TMT bars. 

When the epoxy powder particles are released into a stream of electrically charged air, they are attracted to the grounded TMT bar. As soon as the epoxy particles are attracted to the grounded TMT bar they melt and flow into the anchor profile of the bar. At this point the heat also initiates a chemical reaction helping the epoxy powder molecules to form cross linked polymers which gives the coating its beneficial properties.

The final step to make the best TMT Bars in India consists of curing and cooling wherein the epoxy coated TMT bars are treated thermally at 225°C for a duration sufficient for fully cured coating.

The coated bars are then passed through a cooling tunnel and sprayed with water to cool them from where they are sent to the inspection rack for testing and inspection and quality checks to provide the best TMT Bars in India.

Method of manufacturing Epoxy TMT bars:

At Electrotherm steel, the method of manufacturing various grades of steel bars is of prime importance. We employ the world’s most advanced standards and state-of-the-art machinery to manufacture all our products and variants.

It is well known that steel produced from sponge iron is of the highest quality, hence ET TMT bars are produced from iron ore at the ET TMT’S world class facility following a stringent and streamlined production process.

For this purpose, iron ore is smelted in a blast furnace or a sponge iron kiln. The steel produced from the smelted iron ore is then processed in a steel melting shop from where it reaches the ladle refining furnace. The primary purpose of the ladle refining surface is to remove impurities like phosphorus and sulphur. 

The purified steel is then forwarded to the billet caster where the billets are shaped and these billets are sent for rolling to the rolling mill. Here the billets are rolled into bars to and to give them the grooves for superior bonding with concrete. Once the rolling is complete the next step is the Thermex quenching system. 

It is in the Thermex quenching system that the bars are finally tempered using temperature-controlled water systems.  Here the bars are cooled and tempered by the water flow and they develop the variable structure which has a soft inner core and a hard-outer core. This leads to higher force resistance while maintaining ductility.

Once the bars have cooled, they are checked to ensure that they are free of defects and irregularities. This is done in the physical and chemical labs where both the physical structure as well as the chemical properties of the bars are examined to ensure that only the bars that meet all the quality checks reach the consumer.

Following the lab tests, the bars are certified and then moved on to storage and dispatch where they are stored or distributed.

ET-TMT Refined Steel

All variants of ET TMT bars are made using 100% iron ore and a patented ERF-ELdFOSTM metallurgical process which ensures the elimination of all impurities from iron. This is done to produce refined steel, without impurities. LRF Refined Steel is ideally suited for the production of high-grade TMT bars. 

Unlike some other manufacturers ET TMT only uses in house produced refined steel of the highest quality to ensure that the TMT bars produced at our facilities are the best in quality, longevity and safety.

The main reason for using in-house refined steel instead of scrap steel is that scrap steel contains many impurities and leads to lowering the quality of TMT bars. 

Sulphur and phosphorus (S & P) are impurities in steel which lower its quality significantly. High levels of phosphorus can lead to ‘cold shortness’ in steel which makes it brittle under

extreme cold conditions while high levels of sulphur can

lead to ‘hot shortness’ in steel, a condition in which the

melting point of steel gets lowered thereby reducing its

strength under high temperature.

However, lower levels of the S & P can be achieved only through advanced steel making technology, especially the use of the Ladle Refining Process (LRF).

Our ET TMT bars have superior mechanical properties in strength, weldability, ductility and bendability that exceeds quality standards due to highly stringent quality control process using NABL accredited labs and equipment.

Advantages of Refined Steel in manufacturing TMT bars:

-Lower phosphorus in refined steel improves ductility.

-Lower sulphur in refined steel improves transverse ductility and weldability of the steel.

-Lower carbon level results in excellent ductility and weldability of the refines steel imparting better force resistance to the TMT bars.

-This grade is ideal for construction in areas prone to earthquakes due to better shock resistant properties of the steel.

-Stringent quality control through in-house NABL approved physical and chemical laboratories ensures that only the best products make it to the hands of the consumer.

-This high-quality steel is very suitable for high-rise buildings, bridges, flyovers, dams and industrial structures.

-Since most of the issues causing wear are already avoided there is a higher resistance to failure in the bars.

-The steel helps avoid localised shear failure as well.

Process of manufacturing refined steel:

Steel at Electrotherm is made using high quality raw material. The best quality iron ore is used in a Blast Furnace of 128 m3 and 63 m3, Direct Reduced Iron (DRI) kiln of 250 and 350 TPD. 

For this 100% iron ore is used. Steel scrap is not used in the melting process as it usually contains a high level of impurities. After melting the DRI from kilns and hot metal from Blast Furnace in Induction Furnaces, a unique and patented ERF-ELdFOSTM metallurgical process is used to dephosphorus the steel in the ladle and desulphurised the steel in Electrotherm Ladle Refining Furnace (LRF) specially to meet the stringent phosphorus and sulphur requirement of all grades of TMT bars. 

Multistage testing of steel chemistry on the spectrometer ensures adherence to the desired chemistry in close tolerance.

In the LRF, metal is also homogenised, alloying elements are added and controlled in a very narrow range, dissolved gases in the steel are lowered through mild purging of inert gases and inclusions are removed or altered chemically to ensure high quality of steel. 

This refined steel is cast into billets of required sizes in closed environment to have further control of gases and other inclusions. Molten pig iron (hot metal) from Blast Furnace and Direct Reduced Iron (DRI) from kiln is the key to making superior quality refined steel.

ET TMT bars are free from tramp elements like Cu, V, Ni, Cr etc. because they are manufactured from refined steel, unlike other conventional manufacturers where scrap is used and there is no control on impurities.

After refining the steel in LRF, it is rolled according to the required size in a state-of-the-art Rolling Mill and thermomechanically treated in a Standard Quenching Box. Highly atomised quenching, self-tempering and atmospheric cooling ensures that refined steel TMT bars have superior mechanical properties in strength, weldability, ductility and bendability meeting or exceeding quality standards. Quality control is highly stringent through NABL accredited labs and equipment.

Method of Steel refining:

At ET steel, the method of manufacturing refined steel is the key to our range of high-quality products with unmatched finesse. We employ the world’s most advanced standards and techniques to achieve this.

As steel produced from sponge iron is of the highest quality hence ET TMT bars are produced only from freshly smelted iron ore at the ET TMT’S world class facility following a stringent and streamlined production process.

The iron ore is smelted in a blast furnace or a sponge iron kiln. The steel from the smelted iron ore is then sent to the steel melting shop from where it reaches the ladle refining furnace. In the ladle refining surface, impurities like phosphorus and sulphur are removed. The purified steel is then forwarded to the billet caster and further processing of the billets is done to produce steel bars.

To ensure that the best quality steel is used in our products we refine steel at our own manufacturing facility to ensure that 

The refined steel is cast into billets of required sizes in closed environment to have further control of gases and other inclusions. 

Molten pig iron (hot metal) from Blast Furnace and Direct Reduced Iron (DRI) from kiln is the key to make superior quality refined steel.

Method of manufacturing superior quality steel bars:

Once the billets are ready, they are sent to the rolling mills for being rolled into bars. Here the billets are rolled into their final shape as bars. The rolling also gives them grooves for superior bonding with concrete. After the rolling is done the bars are sent to Thermex quenching system. 

In the Thermex quenching system the bars are tempered using temperature-controlled water systems. Here the bars are cooled and tempered by the water flow and they develop the variable structure with a soft inner core and a hard-outer core. This leads to higher force resistance while maintaining ductility in the bar.

Once the bars have been cooled, they are checked to ensure that they are free of defects and irregularities. This is done in the physical and chemical labs where both the physical structure as well as the chemical properties of the superior quality bars are examined to ensure that only the bars that meet all the quality checks reach the consumer.
