Bajrang TMT – Bajrang Steel

Overview

It is a square cross-sectional metal that is created directly by the process of continuous casting where the liquid steel flows from a furnace to the caster through a copper mold tube. The surface of MS Billets is clear without any scabs or laps due to the smooth copper mold surface. The impure gases in the liquid steel escapes during the solidification process and the chemical alloys are uniformly spread because of the continuous casting technology. TMT bars produced from continuous casting MS Billets show a remarkable consistency of properties because of the high tensile strength and elongation.
