RD TMT is a TMT bar and MS billet manufacturer in Mandya, Karnataka. One plant. Every heat tested.

RDTMT Steels India Private Limited was set up in 2013. The plant is at Somanahalli Industrial Area, Maddur Taluk, Mandya district, between Bengaluru and Mysuru. We melt, cast, roll and test on one site. Our office is at HSR Layout, Bengaluru.

We make Fe 500, Fe 550 and Fe 550D TMT steel bars from 8 mm to 32 mm, rolled on German TEMPCORE lines, and MS billets in 100 mm to 150 mm sections. Both carry the ISI mark under BIS licences to IS 1786:2008 and IS 14650:1999. Every heat is tested in our own NABL accredited lab before it is dispatched.

RD TMT Fe 550 bars are GreenPro certified by CII, and rated 5-star Green Steel by the Ministry of Steel. The bars are approved by Tamil Nadu PWD, KPCL, BDA, Chennai Metro and Karnataka PWD. We supply contractors, developers and government housing programmes through KRIDL, DRDA and APSHCL tenders.

Our journey

From 2013 to today,
in five chapters.

Every date here comes from a certificate, an approval letter or a tender award. You can open each one on the certifications page.

  1. 2013

    Chapter 01 · Founded

    One mill in Mandya, Karnataka

    RDTMT Steels India Private Limited is set up in Karnataka. Work starts on an integrated steel plant at Somanahalli Industrial Area, Maddur Taluk, Mandya. Melting, casting, rolling and testing are planned for one site, so the steel never leaves our hands before it is checked.

  2. 2015

    Chapter 02 · Technology

    German TEMPCORE rolling lines go live

    The rolling mill starts on German TEMPCORE technology. Each bar is water-quenched on the surface while the core stays hot. The result is a hard outer layer over a soft, bendable core. That is what makes a TMT bar both strong and easy to bend on site.

  3. 2024

How we make TMT bars

Made, tested and delivered from one plant.

Three things you can walk up to and check at Somanahalli: the rolling line, the testing lab and the dispatch yard.

The rolling line at the Somanahalli plant01
How the bar is made

German TEMPCORE rolling

Billets are cast in our own furnaces and rolled on German TEMPCORE lines. The surface is quenched hard and the core stays ductile. Every bar carries the RD TMT name and the ISI mark.

How the bar is checked

Every heat tested in our NABL lab

Our in-house lab is NABL accredited to ISO/IEC 17025:2017. Every heat is tested for chemistry, yield strength, elongation and bend before it is cleared. The test certificate goes out with every dispatch.

Delivered across South India

We supply TMT bars from the plant in Mandya and the office in HSR Layout, Bengaluru. Sites in Karnataka, Tamil Nadu and Andhra Pradesh are served by our own dispatch team. A late lorry stops a whole crew, so we plan the delivery date with you.

How we work

Four things we hold ourselves to.

Trust

We only ship steel that has passed our tests. If a heat is in doubt, it does not leave the plant.

Transparency

You get the test certificate with every load, not on request. Our prices, test results and delivery dates are stated plainly.

Loyalty

The person who quoted your order is the person who answers your call after it. We stay with you before, during and after delivery.

Professionalism

We run the plant on certified ISO systems and a NABL accredited lab. Repeat orders from contractors and government bodies are how we measure our work.

Health and safety

Everyone goes home safe. Every shift.

A steel plant is a hard place to work. Our safety system is certified to ISO 45001:2018 since July 2025. PPE is mandatory on the floor. Hazards are marked where they are. Every shift gets safety training, and it is repeated, not filed away.
