pinnacle sizes for roll shells

Over past 10 years as a professional Chinese manufacturer I have exported several kinds of roll sells to Europe and USA, However a buyer from Canada ask for me to process some pinnacle sizes for roll shells. I don’t know how it can be used to. Who tell me how? Thanks.
