Since we are in integrated plant, we manufacture 550D grade quality billets in-house which are low in Sulphur and Phosphorous with high Manganese. These properties always provide higher strength and ductility of our SBF RAPID 550D TMT bars. As per ISI standards, Fe-550D grade TMT bars have ultimate tensile strength of 600 N/mm2 so finally this strength is suitable for any construction.
