At Jai Raj Ispat, innovation meets precision in the production of our Fe 550 D TMT bars, branded as ATOOT 550 D. These bars are manufactured using cutting-edge Endless Casting and Rolling (ECR) technology, developed in collaboration with global metallurgical leader Danieli S.p.A, Italy. Unlike conventional methods, ECR seamlessly integrates the casting and rolling processes into a continuous, uninterrupted flow. This eliminates temperature fluctuations and material inconsistencies, resulting in TMT bars with exceptional uniformity, superior mechanical properties, and unmatched reliability.

This advanced production technique ensures every ATOOT 550 D bar delivers higher tensile strength, enhanced ductility, and excellent weldability, making it the ideal choice for a wide range of construction needs—from residential buildings to high-load infrastructure projects.

For projects requiring even greater strength, Fe 600 grade TMT bars can also be produced on special order, offering maximum performance where it matters most.

KEY FEATURES

UNIFORM STRENGTH
AND FLEXIBILITY

ECR technology creates a refined microstructure in the steel, resulting in uniform strength and flexibility throughout the bar, essential for high-stress applications.

ENERGY EFFICIENCY

Endless casting and rolling reduces energy consumption compared to conventional methods, aligning with Jai Raj Ispat’s commitment to sustainability.

SUPERIOR SURFACE FINISH

This process reduces impurities and scales, producing a smooth, corrosion-resistant surface that enhances the longevity of the bar.

ENHANCED MECHANICAL PROPERTIES

ECR technology improves the bar’s tensile strength, ductility, and seismic resistance, meeting stringent industry standards for Fe 550 D grade steel.

ECO-FRIENDLY PRODUCTION

The process minimizes COâ‚‚ emissions, making it a more environmentally responsible choice in the steel industry.
