The controlled TMT quenching process ensures the standard grade and strength in the rebar. The bar is accompanied by a controlled chemistry & alloys addition to produce the superior grade. Tested and guaranteed Fe 550 D grade ensures safety and helps to save cost because less steel is consumed in this grade. Using SHIVANGI TMT Fe 550D re-bars instead of the regular Fe 415 untested grade available in the market, can save up to 15 – 18% in the total cost of construction.
