There are a number of parameters which dictate the roll selection process providing the best balance between cost and performance. By going through a detailed pre-order process together with our clients, we are able to ensure that they select the right product every time.

Steel grade and roll hardness are two vital components in creating a reliable, high quality manufacturing process. We can provide rolls that offer optimal production output, strip quality and total cost effectiveness.
