TMT Re-bars

JSPL is proud to announce commencement of production of TMT Rebars from its 1 MTPA re-bar mill at PATRATU, JHARKHAND.

JSPL has commenced its 2nd unit at Patratu; state-of-the-art Morgan Rebar Mill of 1.0 million tons per annum capacity, which produces TMT rebars with latest on-line HYQST (High Yield Quenching & Self Tempering technology. The modern mill equipped with METS (Morgan Enhanced Temperature Control System) produces TMT rebars in 8 mm to 40 mm diameter (45mm, 50mm rebars can be supplied subject prior agreement) suitable for high strength applications.

Thermomechanically treated rebars (TMT) involved a combination of plastic deformation of steel in austenitic stage followed by quenching and further tempering. The process controls at each critical operation ensure uniform properties in each rebar and provides the TMT rebar with a soft ferrite & pearlite fine garined core and a strong and tough tempered martensite layer imparting it with high ductility as well as strength thus making it ideal for high rises, dams, bridges, individual houses and any critical structures where high yield strength is required without compromising on the elongation properties. JSPL rebars are made to the latest BIS-1786: 2008 specifications are available in FE Fe 500 / Fe 500D/ Fe 550/ Fe 550 D grades, with Fe 500D grade being highly suitable for seismic prone areas.

JSPL ensures quality in its TMT Rebars at every step, from the input of raw material to the final product delivered on site. With a high automated plant and continuous checks at every level, JSPL is able to produce the best quality rebars in the country. The quality team is equipped with modern testing facilities which ensure that the products meet stringent norms and quality standards.

JSPL is committed to providing complete customer satisfaction with respect to quality, delivery and services. Feedback from the customers acts as inputs for continuous improvement on products and services.
