650,000-800,000 TONS PER YEAR WIRE ROD MILL (USED)

During regular operation before April 2016, the mill had undergone upgradation adopting modern technologies and practices. The mill had capacity more than 800 KTPA with different grades of steel from 5.5 mm to 25 mm including rebar. Grades included free cutting, forging, cold heading, welding electrodes apart from high carbon, low carbon & mesh.

All equipment was lubricated by auto lubrication system. Lubricating Oil and hydraulic oil handling facilities were designed in a safe manner.
