The 4Hi Cold Rolling Mills are used for rolling of coils, sheets and plates of all types of metals and alloys like Stainless Steel, Mild Steel, Brass, Copper, Cupro-Nickel, Aluminum etc. We have manufactured more than 400 such rolling mills running successfully all over India and abroad in countries like Brazil, Turkey, Malaysia, Nigeria, Kenya, Zambia, Tanzania etc. We can manufacture mills upto 800 mm width for harder metals like Stainless Steel and upto 1800 mm width for softer metals like Copper/ Brass/ Aluminum etc. Optimum design and raw materials machined to high accuracy help us achieve close thickness tolerance, flatness and high surface finish on rolled products.
