Quality

Quality is our foremost priority, and it naturally reflects in our output. Industry standards serve as our minimum benchmarks. We strive to maintain superior quality, consistently, and better value for money in our products. Our meticulous attention to detail, from raw material procurement to the delivery of finished goods, ensures customer delight.

Melting of Raw Materials

The initial step in processing raw materials involves melting. To ensure the correct chemical composition, samples of the molten metal are tested in the lab using a spectrometer. Required elements are added as necessary until the desired composition is achieved. This step is critical as it directly affects the quality of the final product.

Finished Goods

The billets are maintained at a controlled temperature to ensure the desired quality of the final product. Our in-house Rolling Mill Laboratory is equipped with a Universal Testing Machine to measure UTS, yield strength, elongation. calibrated weighing scales to determine weight per meter, calibrated vernier calipers determine rod diameter, all in accordance with ISI standards. Only after passing these tests and clearing the lab reports are the TMT Bars approved for delivery and dispatch.

German Thermex Technology

Our KOTHARI TMT Bars, produced using German Thermex Technology (TMX), are of superior quality due to their high tensile strength compared to conventional options. The German Thermex thermo-processing treatment enables the production of exceptionally strong rebars with a yield strength ranging from 550 N/mm² and above. This process enhances robustness, flexibility, weldability, and yieldability. The German Thermex Technology involves a brief but precise in-line cooling of the rolled bar, resulting in a hardened outer layer. Subsequent cooling facilitates thermal exchange (THERMEX) between the inner and outer surfaces of the bar. This process creates a distinct tempered martensite layer on the outer surface and a fine-grained ferrite-pearlite structure in the core, ensuring optimal performance and durability.

German Thermex TMT Reinforced Bars

The patented Thermex cooling technology has significantly benefited the Civil Industry by reducing costs and contributing to the global economy. Here are several reasons why Thermex technology TMT bars are highly preferred and widely accepted:
