Sheets
Cross-rolled sheets, strips and circles are available and can be delivered. Sheets are manufactured in thickness measurements of approximately 0.8 mm to a maximum of 32.5 mm; strips and cuttings are sheared or sawn with company-owned installations to the narrowest tolerances. Circles are laser cut and if requested, they are also equipped with centre- and/or additional holes.
