As a new dawn ignited the financial development of India, intermingled reform ideas were presented in the policy framework of the government. This year, the infrastructure development was being put greater emphasis which in return, wilhncrease the demand for steel. We, at Kamdhenu Limited carry innovation in our veins and stand high to produce products which can fulfill the diverse demands of the masses. In our country, the most challenging task for us is to create something technologically advanced within the affordability of our customers. Constructing a building is like constructing the dream of a new future and innovation is the key towards that. That is when our highly ambitious product Kamdhenu Nxt originated.
Today, there is a lot of population pressure and the cost of land is high. These demographics surely affect the growth in construction sector. Kamdhenu Limited looks forward to receive advantage from the present scenario and the envisaged future construction boom by ensuring the supply of high-end construction products at competitive prices. Mr. Sunil Agarwal. Director, Kamdhenu Limited says. "Our country is foreseeing a record allocation of Rs. 3.96 trillion to infrastructure sector. Therefore, the spotlight on reinforcement structures like ports, roads and other areas like affordable housing, physical infrastructure will provide necessary momentum to the steel sector to meet its growth targets."
The company has planned to utilize every opportunity in the new financial year so as to achieve the set targets and create new demands in the market for innovational steel products like Kamdhenu Nxt. Keeping the pace matched with developmental process with the tactful management of products is the motto of the company in the new world of unlimited possibilities.
Two decades ago, the sun rose with some extra shine, when Kamdhenu Limited laid its first stone. Since then, we have established ourselves on the pinnacle of success, being into the compelling business of building concrete foundations of development. We have put forth our effort to shape the dynamism of Indian infrastructure and have become the first company to offer branded steel products in India. We have stringently followed all the prerequisite parameters for excellence to succeed on the tough path of self establishment.
The company has grown speedily with diversifying business interests like Steel & Paints etc. Keeping our head high on the skies of trust, transparency and integrity; we are ambitious to add much broader section for
Kamdhenu Nxt is manufactured with the cutting edge technology which is at par with the futuristic national and international quality standards. That is why it bears the privilege of being called the ' Next Generation Interlock Steel. It is going to change the definition of modern architectural patterns and designs meant for newly engineered structures. Behind this fact, a profound as well as pragmatic research and development approach resides. A huge team of engineers, contemporary architects and industry experts sat together to derive the distinguished excellence of the product based upon the need of the industry,
Kamdhenu Nxt has got the angular double rib design having obtained all the rights to manufacture, market and sell the exceptionally created double rib TMT bar. With this product, Kamdhenu Limited has reached the zenith of the double rib steel industry.
Kamdhenu Nxt passes through a stringent process to turn into the best double rib TMT bar of the next generation. The strength of this revolutionary product is cautiously controlled by optimizing the water pressure for their core and surface providing an optimum strength, ductility and robustness. The three passing stages in the making of this interlock steel are quenching, tempering and cooling, resultantly, this high end product gets stronger to give impeccable strength to whatsoever application it goes through. The unique design of this TMT which has 'double rib' pattern engraved sets a benchmark of better interlock with concrete mix, giving more power to the structure.
Though steel and concrete are two different materials yet they behave as a single unit in reinforcement structures. It happens when concrete grips the steel rebar to form the strongest bond through the unique double rib pattern of the bar. The CNC notch cutting m/c ensure uniform rib pattern which allows uniform bonding with concrete for the whole structure. Due to uniformity and critically designed ribs, fatigue strength and ductility of Kamdhenu Nxt is much supenor to ordinary steel bars

Kamdhenu Nxt is called the product of the next generation because it has the characteristics to meet the requirements of the new engineered reinforcement structures and smart architectural concepts. The vital features of this high end interlock steel bar are as follows:
In addition to the strength and ductility requirements, reinforce concrete needs adequate bonding between steel and concrete to ensure the composite works efficiently. This perfect bonding is essential for those applications where structures are subject to unexpected forces like seismic, dynamic, impact etc. Therefore, these are widely used in concrete reinforcement structures like bridges, flyovers, dams, thermal and hydel plants, industrial towers, skyline buildings, underground platforms etc. Throughout the making of this next generation double rib TMT bar, each process is highly focused upon so as to not compromise on its quality at any cost, at any stage.
