At Hi-Hard Corporation we produce steel rolls for a variety of applications; these non-heat treated rolls are designed and manufactured specifically as rubber roller cores. Offering rolls with outside diameters up to 36″, and lengths to 200″, all while maintaining tolerances of ±0.0002″. Composed of carbon, alloy, and stainless steel, as well as aluminum and iron, all are manufactured on state of the art precision CNC machining equipment. Quality control is maintained through a variety of testing including dimensional testing, hardness testing, NDT testing, and surface finish testing. All orders can be produced with a minimum of four weeks lead time to customers across the US, Canada, and Mexico.

Hi-Hard Corporation produces a line of products in solid and fabricated construction that requires no heat treatment. These rolls are made from a variety of different materials such as stainless steel, alloy steel, or aluminum.
