Corrosion Resistant Steel (CRS) Bars
ET TMT CRS bars are an example of ‘Innovation meets product excellence’. Striking a fine balance between the life of the structure and its cost, these corrosion-resistant bars help in reducing the rate of corrosion from the time of construction and thus enhances the life span of the structure.
CRS TMT bars are produced with an addition of corrosion resistance elements such as copper, chromium, and phosphorus. Thus, are considered to be more advanced and have a longer life than ordinary TMT bars. ET TMT CRS comprises CRS Fe 500 and CRS Fe 500 D grades. The high corrosion resistant feature makes them an ideal choice for projects near coastal areas and structures such as bridges and dams.

Advantages of ET CRS Bars:
- Made from high quality BIS certified billets produced in-house
- Longer life due to superior pitting corrosion resistance
- Can be bent and re-bent around very small mandrels
- High yield strength coupled with ductility and bendability
- Stringent quality control through NABL accredited in-house physical and chemical laboratories
- Suitable for application in seismic zones
- Single largest production capacity of TMT bars in Gujarat 5.0 LTPA
The process of making ET TMT CRS Bars
Captively produced billets ensure that high quality input is available for production of CRS bars. Even these captive billets are produced using high quality sponge iron produced in-house. The steel is made to an accurate chemical composition. Spectrometer testing ensures that the chemistry is precisely controlled in every heat of billets produced. Corrosion resistance elements like copper, phosphorus, and chromium are added in the correct proportion to make the steel resistant to corrosion.
The quenching technology used after rolling ensures that there is a presence of selftempered layer over martensitic layer. This ensures high strength with high ductility. The distribution of corrosion resistance elements is homogeneous from the core to the surface. The high strength enables the steel to resist applied forces. The high ductility ensures the steel can undergo permanent changes in shape without rupturing.
