Our Precis. Founded in the year 2011, we, Bajrang Tools And Rolls Pvt. Ltd., are a distinguished Manufacturer, Supplier and Exporter of a broad range of Cold Rolling Mill Rolls and Hot Rolling Mill Rolls used in mills. These products are widely used in the metal forming industry owing to their robust design, outstanding performance and minimal maintenance.
Meticulous care is taken in grinding the surfaces of coldrolling mill rolls and in carrying out annealing and pickling operations of the products so as to provide attractive surface finishes inherent to stainless steel. Products requiring finishes ranging from No. 3 to Buffing polished and hairline finishes can also be produced to order.
There is also an inbetween finishing hot rolling process called "P O" (Pickled and Oiled). In this case, the hot rolled steel is pickled in acid to remove the mill scale and then oiled to keep it from rusting. The cost is somewhere in between that of regular hot rolled and cold rolled.
