Enhancing Structural Integrity with NR TMT and NRTMT SUPER Rebars

When it comes to reinforcing concrete and masonry structures, ensuring their strength and durability is of paramount importance. That's where our NR TMT and NRTMT SUPER (thermo-mechanically-treated) rebars come into play. These remarkable steel bars are designed to fortify and support structures under tension, elevating their tensile strength to new heights. To give you a visual insight into their robustness, we've included some enticing ribbed bar images.

Our Manufacturing Excellence

At the heart of our TMT production lies an integrated manufacturing process that begins with ironmaking. We meticulously process high-grade iron ore and pellets in our state-of-the-art facilities, transforming them into top-tier sponge iron. Subsequently, this sponge iron undergoes conversion into crude steel within our steel melting shop. This rigorous process ensures the exceptional quality of our TMT bars.

The Fe 550 Advantage

Our flagship offering in the TMT bar category is the Fe 550 variant. This type of TMT bar is specially crafted for structures that bear substantial weight, making it an ideal choice for high-rise buildings and other demanding construction projects. The 'Fe' denotes the iron content within the bar, while '550' signifies the minimum yield strength it possesses. Fe 550 TMT bars exhibit superior tensile strength compared to their predecessors, making them a reliable choice for structural enhancement.
