SAIL TMT (Thermo-Mechanically Treated) bars are the quality reinforcement steel manufactured by SAIL, which is the leading public-sector steel manufacturer in India. These rebars are designed to be used in modern infrastructure and building and have superior strength, ductility, weldability, and bond properties. Produced in SAIL integrated steel plants as per Grade IS 1786 specifications, SAIL TMT bars are available nationwide and can be used in a wide range of structural applications, including earthquake-resistant housing, medium- and heavy-industrial projects, etc.

SAIL TMT Q&A: Top 10 FAQs

1. What is SAIL TMT?
SAIL TMT is the SAIL brand of thermo-mechanically treated reinforcement bars. These bars are manufactured using quenching and self-tempering processes and comply with IS 1786 specification of high-strength reinforcement steels. SAIL sells standard TMT rebars as well as high-end ones called SeQR, which are aimed at high flexibility and structural performance.

2. How did SAIL TMT come into being?
SAIL has been associated with the Indian steel industry since its inception in 1973 and with steelmaking since the inception of Hindustan Steel in 1954. TMT bars of high grade have been produced in different integrated plants (Bhilai, Bokaro, Durgapur, Rourkela, Burnpur) over several decades. The SeQR line was developed to improve seismic performance and flexibility of residential buildings.

3. What is the ownership of SAIL TMT?
SAIL TMT is a government-owned steel company owned and operated by SAIL, a Maharatna steel company under the Ministry of Steel of India. SAIL has its headquarters in New Delhi and is the second-largest steel manufacturer in the country, with five integrated steel plants and specialized plants across the country.

4. Which products are provided under SAIL TMT?
There are two primary product lines that SAIL provides:
SAIL TMT Bars: The common reinforcement bars (rebars) that meet the requirements of IS 1786 Grade Fe 500D.
SAIL SeQR TMT Bars: High-tech rebars that have improved tensile and flexibility characteristics and are suitable in earthquake-prone areas. First introduced in 8 mm-20 mm diameter, 12 m length.
Other SAIL products supplement these, such as wire rods, galvanized sheets, plates, railway wheels, and automotive-grade steel, but the TMT brands are separate.

5. How much do SAIL TMT bars cost?
SAIL usually sells TMT bars to dealers and stockyards at prices that are tied to market forces and are supplied to the city limits. Although precise real-time prices will depend on the location and the size of the bar, the standardized uniformity of SAIL guarantees transparency and consistency across regions (local rates can be obtained through authorized dealers).

6. Where can I find SAIL TMT bars?
SAIL has a distribution network across the country with integrated plants and marketing offices at Bhilai, Bokaro, Durgapur, Rourkela, Burnpur, Salem, Bhadravathi, and others. This coverage guarantees the availability of products in India and support of regional stock points.

7. What are the grades?
SAIL TMT products are IS 1786 standard.
Standard TMT—Grade Fe 500D
SeQR TMT—Seismic Resilient Grade (Fe 500D or more)
These grades guarantee good tensile strength, ductility, and bonding, which are important in safe and durable construction.

8. What are the mechanical and physical properties?
The SAIL TMT bars are manufactured by thermo-mechanical control processing to obtain a tri-layered microstructure:
High-strength outer martensitic layer
Toughness intermediate bainitic core
Elasticity and ductility of the inner ferrite-pearlite core

Important characteristic features:
Yield Strength: 500 MPa (Fe 500D)
Ultimate Tensile Strength: SeQR performance observed
Ductility: It is high and makes it seismically compliant and welds well.
These bars can be used in earthquake-resistant buildings and have better weldability and bond strength.

9. What are the sizes available?
TMT bars of SAIL are available in a broad range of diameters.
Coil form: 6 mm, 8 mm, 10 mm (wire rod mill)
Straight lengths: 8, 10, 12, 16, 20, 22, 25, 28, 32, 36, and 40 mm (bar mill)
Normal lengths are usually 12 m.
The SeQR bars were originally 8 mm to 20 mm in diameter and 12 m in standard length.

10. In what way can one reach SAIL TMT?
SAIL provides a number of ways of contact:
1. New Delhi Corporate Headquarters
2. Plant offices integrated in Bhilai, Durgapur, Bokaro, Rourkela, and Burnpur
3. Special steel plants at Salem and Bhadravathi
4. Marketing offices and dealer networks that receive inquiries, make purchases, and distribute to all parts of the country
5. The SAIL website has a dealer locator and inquiry forms to communicate directly.
