Jacket rolls with a multi-tube structure are manufactured through various processes such as material arrangement, heat treatment, machining, welding, grinding, hard chrome plating, and mirror finishing.
We strive to maintain high quality roll production by conducting welding and non-destructive inspection by qualified personnel.
We will guide you through the process from ordering to product completion.
When an order comes, we take the design drawing from the custmer and then arrange necessary materials.
